Normalize the g(eom,cache,part,...) build.
Rather then combining hardlink creation for the geom(8) binary with shared library build, move libraries to src/lib/geom so they are built and installed normally. Create a common Makefile.classes which is included by both lib/geom/Makefile and sbin/geom/Makefile so the symlink and libraries stay in sync. The relocation of libraries allows libraries to be build for 32-bit compat. This also reduces the number of non-standard builds in the system. This commit is not sufficent to run a 32-bit /sbin/geom on a 64-bit system out of the box as it will look in the wrong place for libraries unless GEOM_LIBRARY_PATH is set appropriatly in the environment.

-.Op Fl v
-.Sh DESCRIPTION
-The
-.Nm
-utility is used to control GEOM cache, which can
-speed up read performance by sending fixed size
-read requests to its consumer. It has been developed to address
-the problem of a horrible read performance of a 64k blocksize FS
-residing on a RAID3 array with 8 data components, where a single
-disk component would only get 8k read requests, thus effectively
-killing disk performance under high load.
-.Pp
-Caching can be configured using two different methods:
-.Dq manual
-or
-.Dq automatic .
-When using the
-.Dq manual
-method, no metadata are stored on the devices, so the cached
-device has to be configured by hand every time it is needed.
-The
-.Dq automatic
-method uses on-disk metadata to detect devices.
-Once devices are labeled, they will be automatically detected and
-configured.
-.Pp
-The first argument to
-.Nm
-indicates an action to be performed:
-.Bl -tag -width ".Cm destroy"
-.It Cm create
-Cache the given devices with specified
-.Ar name .
-This is the
-.Dq manual
-method.
-The kernel module
-.Pa geom_cache.ko
-will be loaded if it is not loaded already.
-.It Cm label
-Cache the given devices with the specified
-.Ar name .
-This is the
-.Dq automatic
-method, where metadata are stored in every device's last sector.
-The kernel module
-.Pa geom_cache.ko
-will be loaded if it is not loaded already.
-.It Cm stop
-Turn off existing cache device by its
-.Ar name .
-This command does not touch on-disk metadata!
-.It Cm destroy
-Same as
-.Cm stop .
-.It Cm clear
-Clear metadata on the given devices.
-.It Cm dump
-Dump metadata stored on the given devices.
-.It Cm list
-See
-.Xr geom 8 .
-.It Cm status
-See
-.Xr geom 8 .
-.It Cm load
-See
-.Xr geom 8 .
-.It Cm unload
-See
-.Xr geom 8 .
-.El
-.Pp
-Additional options:
-.Bl -tag -width indent
-.It Fl f
-Force the removal of the specified cache device.
-.It Fl v
-Be more verbose.
-.El
-.Sh SYSCTL VARIABLES
-The following
-.Xr sysctl 8
-variables can be used to control the behavior of the
-.Nm CACHE
-GEOM class.
-The default value is shown next to each variable.
-.Bl -tag -width indent
-.It Va kern.geom.cache.used_hi : No 20
-.It Va kern.geom.cache.used_lo : No 5
-.It Va kern.geom.cache.idletime : No 5
-.It Va kern.geom.cache.timeout : No 10
-.It Va kern.geom.cache.enable : No 1
-.It Va kern.geom.cache.debug : No 0
-Debug level of the
-.Nm CACHE
-GEOM class.
-This can be set to a number between 0 and 3 inclusive.
-If set to 0 minimal debug information is printed, and if set to 3 the
-maximum amount of debug information is printed.
-.El
-.Sh EXIT STATUS
-Exit status is 0 on success, and 1 if the command fails.
-.Sh SEE ALSO
-.Xr geom 4 ,
-.Xr geom 8
-.Sh HISTORY
-The
-.Nm
-utility appeared in
-.Fx 7.0 .

-.Cm destroy
-.Op Fl fv
-.Ar name ...
-.Nm
-.Cm label
-.Op Fl hv

-.Nm
-.Cm list
-.Nm
-.Cm status
-.Nm
-.Cm load
-.Nm
-.Cm unload
-.Sh DESCRIPTION
-The
-.Nm
-utility is used for device concatenation configuration.
-The concatenation can be configured using two different methods:
-.Dq manual
-or
-.Dq automatic .
-When using the
-.Dq manual
-method, no metadata are stored on the devices, so the concatenated
-device has to be configured by hand every time it is needed.
-The
-.Dq automatic
-method uses on-disk metadata to detect devices.
-Once devices are labeled, they will be automatically detected and
-configured.
-.Pp
-The first argument to
-.Nm
-indicates an action to be performed:
-.Bl -tag -width ".Cm destroy"
-.It Cm create
-Concatenate the given devices with specified
-.Ar name .
-This is the
-.Dq manual
-method.
-The kernel module
-.Pa geom_concat.ko
-will be loaded if it is not loaded already.
-.It Cm label
-Concatenate the given devices with the specified
-.Ar name .
-This is the
-.Dq automatic
-method, where metadata are stored in every device's last sector.
-The kernel module
-.Pa geom_concat.ko
-will be loaded if it is not loaded already.
-.It Cm stop
-Turn off existing concatenate device by its
-.Ar name .
-This command does not touch on-disk metadata!
-.It Cm destroy
-Same as
-.Cm stop .
-.It Cm clear
-Clear metadata on the given devices.
-.It Cm dump
-Dump metadata stored on the given devices.
-.It Cm list
-See
-.Xr geom 8 .
-.It Cm status
-See
-.Xr geom 8 .
-.It Cm load
-See
-.Xr geom 8 .
-.It Cm unload
-See
-.Xr geom 8 .
-.El
-.Pp
-Additional options:
-.Bl -tag -width indent
-.It Fl f
-Force the removal of the specified concatenated device.
-.It Fl h
-Hardcode providers' names in metadata.
-.It Fl v
-Be more verbose.
-.El
-.Sh SYSCTL VARIABLES
-The following
-.Xr sysctl 8
-variables can be used to control the behavior of the
-.Nm CONCAT
-GEOM class.
-The default value is shown next to each variable.
-.Bl -tag -width indent
-.It Va kern.geom.concat.debug : No 0
-Debug level of the
-.Nm CONCAT
-GEOM class.
-This can be set to a number between 0 and 3 inclusive.
-If set to 0 minimal debug information is printed, and if set to 3 the
-maximum amount of debug information is printed.
-.El
-.Sh EXIT STATUS
-Exit status is 0 on success, and 1 if the command fails.
-.Sh EXAMPLES
-The following example shows how to configure four disks for automatic
-concatenation, create a file system on it, and mount it:
-.Bd -literal -offset indent
-gconcat label -v data /dev/da0 /dev/da1 /dev/da2 /dev/da3
-newfs /dev/concat/data
-mount /dev/concat/data /mnt
-[...]
-umount /mnt
-gconcat stop data
-gconcat unload
-.Ed
-.Pp
-Configure concatenated provider on one disk only.
-Create file system.
-Add two more disks and extend existing file system.
-.Bd -literal -offset indent
-gconcat label data /dev/da0
-newfs /dev/concat/data
-gconcat label data /dev/da0 /dev/da1 /dev/da2
-growfs /dev/concat/data

-.Sh DESCRIPTION
-The
-.Nm
-utility is used to configure encryption on GEOM providers.
-.Pp
-The following is a list of the most important features:
-.Pp
-.Bl -bullet -offset indent -compact
-.It
-Utilizes the
-.Xr crypto 9
-framework, so when there is crypto hardware available,
-.Nm
-will make use of it automatically.
-.It
-Supports many cryptographic algorithms (currently
-.Nm AES-XTS ,
-.Nm AES-CBC ,
-.Nm Blowfish-CBC ,
-.Nm Camellia-CBC
-and
-.Nm 3DES-CBC ) .
-.It
-Can optionally perform data authentication (integrity verification) utilizing
-one of the following algorithms:
-.Nm HMAC/MD5 ,
-.Nm HMAC/SHA1 ,
-.Nm HMAC/RIPEMD160 ,
-.Nm HMAC/SHA256 ,
-.Nm HMAC/SHA384
-or
-.Nm HMAC/SHA512 .
-.It
-Can create a User Key from up to two, piecewise components: a passphrase
-entered via prompt or read from one or more passfiles; a keyfile read from
-one or more files.
-.It
-Allows encryption of the root partition.
-The user will be asked for the
-passphrase before the root file system is mounted.
-.It
-Strengthens the passphrase component of the User Key with:
-.Rs
-.%A B. Kaliski
-.%T "PKCS #5: Password-Based Cryptography Specification, Version 2.0."
-.%R RFC
-.%N 2898
-.Re
-.It
-Allows the use of two independent User Keys (e.g., a
-.Qq "user key"
-and a
-.Qq "company key" ) .
-.It
-It is fast -
-.Nm
-performs simple sector-to-sector encryption.
-.It
-Allows the encrypted Master Key to be backed up and restored,
-so that if a user has to quickly destroy key material,
-it is possible to get the data back by restoring keys from
-backup.
-.It
-Providers can be configured to automatically detach on last close
-(so users do not have to remember to detach providers after unmounting
-the file systems).
-.It
-Allows attaching a provider with a random, one-time Master Key -
-useful for swap partitions and temporary file systems.
-.It
-Allows verification of data integrity (data authentication).
-.It
-Allows suspending and resuming encrypted devices.
-.El
-.Pp
-The first argument to
-.Nm
-indicates an action to be performed:
-.Bl -tag -width ".Cm configure"
-.It Cm init
-Initialize the provider which needs to be encrypted.
-Here you can set up the cryptographic algorithm to use, Data Key length,
-etc.
-The last sector of the provider is used to store metadata.
-The

-.Nm HMAC/SHA1 ,
-.Nm HMAC/RIPEMD160 ,
-.Nm HMAC/SHA256 ,
-.Nm HMAC/SHA384
-and
-.Nm HMAC/SHA512 .
-If the option is not given, there will be no authentication, only encryption.
-The recommended algorithm is
-.Nm HMAC/SHA256 .
-.It Fl b
-Try to decrypt this partition during boot, before the root partition is mounted.
-This makes it possible to use an encrypted root partition.
-One will still need bootable unencrypted storage with a

-after boot.
-.It Fl B Ar backupfile
-File name to use for metadata backup instead of the default

-.It Fl g
-Enable booting from this encrypted root filesystem.
-The boot loader prompts for the passphrase and loads
-.Xr loader 8
-from the encrypted partition.
-.It Fl i Ar iterations
-Number of iterations to use with PKCS#5v2 when processing User Key
-passphrase component.
-If this option is not specified,
-.Nm
-will find the number of iterations which is equal to 2 seconds of crypto work.
-If 0 is given, PKCS#5v2 will not be used.
-PKCS#5v2 processing is performed once, after all parts of the passphrase
-component have been read.
-.It Fl J Ar newpassfile
-Specifies a file which contains the passphrase component of the User Key
-(or part of it).
-If
-.Ar newpassfile
-is given as -, standard input will be used.
-Only the first line (excluding new-line character) is taken from the given file.
-This argument can be specified multiple times, which has the effect of
-reassembling a single passphrase split across multiple files.
-Cannot be combined with the
-.Fl P
-option.
-.It Fl K Ar newkeyfile
-Specifies a file which contains the keyfile component of the User Key
-(or part of it).
-If

-option.
-.It Fl s Ar sectorsize
-Change decrypted provider's sector size.
-Increasing the sector size allows increased performance,
-because encryption/decryption which requires an initialization vector
-is done per sector; fewer sectors means less computational work.
-.It Fl T
-Don't pass through
-.Dv BIO_DELETE
-calls (i.e., TRIM/UNMAP).
-This can prevent an attacker from knowing how much space you're actually
-using and which sectors contain live data, but will also prevent the
-backing store (SSD, etc) from reclaiming space you're not using, which
-may degrade its performance and lifespan.
-The underlying provider may or may not actually obliterate the deleted
-sectors when TRIM is enabled, so it should not be considered to add any
-security.
-.It Fl V Ar version
-Metadata version to use.
-This option is helpful when creating a provider that may be used by older
-.Nm FreeBSD/GELI
-versions.
-Consult the

-.It Fl C
-Do a dry-run decryption.
-This is useful to verify passphrase and keyfile without decrypting the device.
-.It Fl d
-If specified, a decrypted provider will be detached automatically on last close.
-This can help with scarce memory so the user does not have to remember to detach the
-provider after unmounting the file system.
-It only works when the provider was opened for writing, so it will not work if
-the file system on the provider is mounted read-only.
-Probably a better choice is the

-.El
-.It Cm kill
-This command should be used only in emergency situations.
-It will destroy all copies of the Master Key on a given provider and will
-detach it forcibly (if it is attached).
-This is absolutely a one-way command - if you do not have a metadata
-backup, your data is gone for good.
-In case the provider was attached with the
-.Fl r

-.It Cm suspend
-Suspend device by waiting for all inflight requests to finish, clearing all
-sensitive information (like the Master Key and Data Keys) from kernel memory,
-and blocking all further I/O requests until the
-.Cm resume
-subcommand is executed.
-This functionality is useful for laptops: when one wants to suspend a
-laptop, one does not want to leave an encrypted device attached.
-Instead of closing all files and directories opened from a file system located
-on an encrypted device, unmounting the file system, and detaching the device,
-the
-.Cm suspend
-subcommand can be used.
-Any access to the encrypted device will be blocked until the Master Key is
-reloaded through the
-.Cm resume
-subcommand.
-Thus there is no need to close nor unmount anything.
-The
-.Cm suspend
-subcommand does not work with devices created with the
-.Cm onetime
-subcommand.
-Please note that sensitive data might still be present in memory after
-suspending an encrypted device due to the file system cache, etc.

-.It Fl a
-Suspend all
-.Nm
-devices.
-.El
-.It Cm resume
-Resume previously suspended device.
-The caller must ensure that executing this subcommand does not access the

-.Sh KEY SUMMARY
-.Ss Master Key
-Upon
-.Cm init ,
-the
-.Nm
-utility generates a random Master Key for the provider.
-The Master Key never changes during the lifetime of the provider.
-Each copy of the provider metadata, active or backed up to a file, can store
-up to two, independently-encrypted copies of the Master Key.
-.Ss User Key
-Each stored copy of the Master Key is encrypted with a User Key, which
-is generated by the
-.Nm
-utility from a passphrase and/or a keyfile.
-The
-.Nm
-utility first reads all parts of the keyfile in the order specified on the
-command line, then reads all parts of the stored passphrase in the order
-specified on the command line.
-If no passphrase parts are specified, the system prompts the user to enter
-the passphrase.
-The passphrase is optionally strengthened by PKCS#5v2.
-The User Key is a digest computed over the concatenated keyfile and passphrase.
-.Ss Data Key
-During operation, one or more Data Keys are deterministically derived by
-the kernel from the Master Key and cached in memory.
-The number of Data Keys used by a given provider, and the way they are
-derived, depend on the GELI version and whether the provider is configured to
-use data authentication.
-.Sh SYSCTL VARIABLES
-The following
-.Xr sysctl 8
-variables can be used to control the behavior of the
-.Nm ELI
-GEOM class.
-The default value is shown next to each variable.
-Some variables can also be set in
-.Pa /boot/loader.conf .
-.Bl -tag -width indent
-.It Va kern.geom.eli.version
-Version number of the
-.Nm ELI
-GEOM class.
-.It Va kern.geom.eli.debug : No 0
-Debug level of the
-.Nm ELI
-GEOM class.
-This can be set to a number between 0 and 3 inclusive.
-If set to 0, minimal debug information is printed.
-If set to 3, the
-maximum amount of debug information is printed.
-.It Va kern.geom.eli.tries : No 3
-Number of times a user is asked for the passphrase.
-This is only used for providers which are attached on boot
-(before the root file system is mounted).
-If set to 0, attaching providers on boot will be disabled.
-This variable should be set in
-.Pa /boot/loader.conf .
-.It Va kern.geom.eli.overwrites : No 5
-Specifies how many times the Master Key will be overwritten
-with random values when it is destroyed.
-After this operation it is filled with zeros.
-.It Va kern.geom.eli.visible_passphrase : No 0
-If set to 1, the passphrase entered on boot (before the root
-file system is mounted) will be visible.
-This alternative should be used with caution as the entered
-passphrase can be logged and exposed via
-.Xr dmesg 8 .
-This variable should be set in
-.Pa /boot/loader.conf .
-.It Va kern.geom.eli.threads : No 0
-Specifies how many kernel threads should be used for doing software
-cryptography.
-Its purpose is to increase performance on SMP systems.
-If set to 0, a CPU-pinned thread will be started for every active CPU.
-.It Va kern.geom.eli.batch : No 0
-When set to 1, can speed-up crypto operations by using batching.
-Batching reduces the number of interrupts by responding to a group of
-crypto requests with one interrupt.
-The crypto card and the driver has to support this feature.
-.It Va kern.geom.eli.key_cache_limit : No 8192
-Specifies how many Data Keys to cache.
-The default limit
-(8192 keys) will allow caching of all keys for a 4TB provider with 512 byte
-sectors and will take around 1MB of memory.
-.It Va kern.geom.eli.key_cache_hits
-Reports how many times we were looking up a Data Key and it was already in
-cache.
-This sysctl is not updated for providers that need fewer Data Keys than
-the limit specified in
-.Va kern.geom.eli.key_cache_limit .
-.It Va kern.geom.eli.key_cache_misses
-Reports how many times we were looking up a Data Key and it was not in cache.
-This sysctl is not updated for providers that need fewer Data Keys than the limit
-specified in
-.Va kern.geom.eli.key_cache_limit .
-.El
-.Sh EXIT STATUS
-Exit status is 0 on success, and 1 if the command fails.

-Initialize provider with the passphrase split into two files.
-The provider can be attached using those two files or by entering
-.Dq foobar
-as the passphrase at the
-.Nm
-prompt:
-.Bd -literal -offset indent
-# echo foo > da0.pass0
-# echo bar > da0.pass1
-# geli init -J da0.pass0 -J da0.pass1 da0
-# geli attach -j da0.pass0 -j da0.pass1 da0
-# geli detach da0
-# geli attach da0
-Enter passphrase: foobar

-Suspend all
-.Nm
-devices on a laptop, suspend the laptop, then resume devices one by one after
-resuming the laptop:
-.Bd -literal -offset indent
-# geli suspend -a

-<resume your laptop>
-# geli resume -p -k keyfile gpt/secret

-Enter passphrase:

-.Sh ENCRYPTION MODES
-.Nm
-supports two encryption modes:
-.Nm XTS ,
-which was standardized as
-.Nm IEEE P1619
-and
-.Nm CBC
-with unpredictable IV.
-The
-.Nm CBC
-mode used by
-.Nm
-is very similar to the mode
-.Nm ESSIV .
-.Sh DATA AUTHENTICATION
-.Nm
-can verify data integrity when an authentication algorithm is specified.
-When data corruption/modification is detected,
-.Nm
-will not return any data, but instead will return an error
-.Pq Er EINVAL .
-The offset and size of the corrupted data will be printed on the console.
-It is important to know against which attacks
-.Nm
-provides protection for your data.
-If data is modified in-place or copied from one place on the disk
-to another even without modification,
-.Nm
-should be able to detect such a change.
-If an attacker can remember the encrypted data, he can overwrite any future
-changes with the data he owns without it being noticed.
-In other words
-.Nm
-will not protect your data against replay attacks.
-.Pp
-It is recommended to write to the whole provider before first use,
-in order to make sure that all sectors and their corresponding
-checksums are properly initialized into a consistent state.
-One can safely ignore data authentication errors that occur immediately
-after the first time a provider is attached and before it is
-initialized in this way.

-.Op Fl fv

-.Nm
-.Cm unload
-.Sh DESCRIPTION
-The
-.Nm
-utility is used for journal configuration on the given GEOM provider.
-The Journal and data may be stored on the same provider or on two separate
-providers.
-This is block level journaling, not file system level journaling, which means
-everything gets logged, e.g.\& for file systems, it journals both data and
-metadata.
-The
-.Nm
-GEOM class can talk to file systems, which allows the use of
-.Nm
-for file system journaling and to keep file systems in a consistent state.
-At this time, only UFS file system is supported.
-.Pp
-To configure journaling on the UFS file system using
-.Nm ,
-one should first create a
-.Nm
-provider using the
-.Nm
-utility, then run
-.Xr newfs 8
-or
-.Xr tunefs 8
-on it with the
-.Fl J
-flag which instructs UFS to cooperate with the
-.Nm
-provider below.
-There are important differences in how journaled UFS works.
-The most important one is that
-.Xr sync 2
-and
-.Xr fsync 2
-system calls do not work as expected anymore.
-To ensure that data is stored on the data provider, the
-.Nm Cm sync
-command should be used after calling
-.Xr sync 2 .
-For the best performance possible, soft-updates should be disabled when
-.Nm
-is used.
-It is also safe and recommended to use the
-.Cm async
-.Xr mount 8
-option.
-.Pp
-When
-.Nm
-is configured on top of
-.Xr gmirror 8
-or
-.Xr graid3 8
-providers, it also keeps them in a consistent state, thus
-automatic synchronization on power failure or system crash may be disabled
-on those providers.
-.Pp
-The
-.Nm
-utility uses on-disk metadata, stored in the provider's last sector,
-to store all needed information.
-This could be a problem when an existing file system is converted to use
-.Nm .
-.Pp
-The first argument to
-.Nm
-indicates an action to be performed:
-.Bl -tag -width ".Cm status"
-.It Cm label
-Configures
-.Nm
-on the given provider(s).
-If only one provider is given, both data and journal are stored on the same
-provider.
-If two providers are given, the first one will be used as data provider and the
-second will be used as the journal provider.
-.Pp
-Additional options include:
-.Bl -tag -width ".Fl s Ar jsize"
-.It Fl c
-Checksum journal records.
-.It Fl f
-May be used to convert an existing file system to use
-.Nm ,
-but only if the journal will be configured on a separate provider and if the
-last sector in the data provider is not used by the existing file system.
-If
-.Nm
-detects that the last sector is used, it will refuse to overwrite it
-and return an error.
-This behavior may be forced by using the
-.Fl f
-flag, which will force
-.Nm
-to overwrite the last sector.
-.It Fl h
-Hardcode provider names in metadata.
-.It Fl s Ar jsize
-Specifies size of the journal if only one provider is used for both data and
-journal.
-The default is one gigabyte.
-Size should be chosen based on provider's load, and not on its size;
-recommended minimum is twice the size of the physical memory installed.
-It is not recommended to use
-.Nm
-for small file systems (e.g.: only few gigabytes big).
-.El
-.It Cm clear
-Clear metadata on the given providers.
-.It Cm stop
-Stop the given provider.
-.Pp
-Additional options include:
-.Bl -tag -width ".Fl f"
-.It Fl f
-Stop the given provider even if it is opened.
-.El
-.It Cm sync
-Trigger journal switch and enforce sending data to the data provider.
-.It Cm dump
-Dump metadata stored on the given providers.
-.It Cm list
-See
-.Xr geom 8 .
-.It Cm status
-See
-.Xr geom 8 .
-.It Cm load
-See
-.Xr geom 8 .
-.It Cm unload
-See
-.Xr geom 8 .
-.El
-.Pp
-Additional options include:
-.Bl -tag -width ".Fl v"
-.It Fl v
-Be more verbose.
-.El
-.Sh EXIT STATUS
-Exit status is 0 on success, and 1 if the command fails.
-.Sh EXAMPLES
-Create a
-.Nm
-based UFS file system and mount it:
-.Bd -literal -offset indent
-gjournal load
-gjournal label da0
-newfs -J /dev/da0.journal
-mount -o async /dev/da0.journal /mnt
-.Ed
-.Pp
-Configure journaling on an existing file system, but only if
-.Nm
-allows this (i.e., if the last sector is not already used by the file system):
-.Bd -literal -offset indent
-umount /dev/da0s1d
-gjournal label da0s1d da0s1e && \e
- tunefs -J enable -n disable da0s1d.journal && \e
- mount -o async /dev/da0s1d.journal /mnt || \e
- mount /dev/da0s1d /mnt
-.Ed
-.Sh SYSCTLS
-Gjournal adds the sysctl level kern.geom.journal.
-The string and integer information available is detailed below.
-The changeable column shows whether a process with appropriate privilege may
-change the value.
-.Bl -column "accept_immediatelyXXXXXX" integerXXX -offset indent
-.It Sy "sysctl name Type Changeable"
-.It "debug integer yes"

-.It Li debug
-Setting a non-zero value enables debugging at various levels.
-Debug level 1 will record actions at a journal level, relating to journal
-switches, metadata updates, etc.
-Debug level 2 will record actions at a higher level, relating to the numbers of
-entries in journals, access requests, etc.
-Debug level 3 will record verbose detail, including insertion of I/Os to the
-journal.
-.It Li switch_time

-.Sh DESCRIPTION
-The
-.Nm
-utility is used for GEOM provider labelization.
-A label can be set up on a GEOM provider in two ways:
-.Dq manual
-or
-.Dq automatic .
-When using the
-.Dq manual
-method, no metadata are stored on the devices, so a label has to be configured
-by hand every time it is needed.
-The
-.Dq automatic
-method uses on-disk metadata to store the label and detect it automatically in
-the future.
-.Pp
-This GEOM class also provides volume label detection for file systems.
-Those labels cannot be set with
-.Nm ,
-but must be set with the appropriate file system utility, e.g.\& for UFS
-the file system label is set with
-.Xr tunefs 8 .
-Currently supported file systems are:
-.Pp
-.Bl -bullet -offset indent -compact
-.It
-UFS1 volume names (directory
-.Pa /dev/ufs/ ) .
-.It
-UFS2 volume names (directory
-.Pa /dev/ufs/ ) .
-.It
-UFS1 file system IDs (directory
-.Pa /dev/ufsid/ ) .
-.It
-UFS2 file system IDs (directory
-.Pa /dev/ufsid/ ) .
-.It
-MSDOSFS (FAT12, FAT16, FAT32) (directory
-.Pa /dev/msdosfs/ ) .
-.It
-CD ISO9660 (directory
-.Pa /dev/iso9660/ ) .
-.It
-EXT2FS (directory
-.Pa /dev/ext2fs/ ) .
-.It
-REISERFS (directory
-.Pa /dev/reiserfs/ ) .
-.It
-NTFS (directory
-.Pa /dev/ntfs/ ) .
-.El
-.Pp
-Support for partition metadata is implemented for:
-.Pp
-.Bl -bullet -offset indent -compact
-.It
-GPT labels (directory
-.Pa /dev/gpt/ ) .
-.It
-GPT UUIDs (directory
-.Pa /dev/gptid/ ) .
-.El
-.Pp
-Generic disk ID strings are exported as labels in the format
-.Pa /dev/diskid/GEOM_CLASS-ident
-e.g.
-.Pa /dev/diskid/DISK-6QG3Z026 .
-.Pp
-Generic labels created and managed solely by
-.Xr glabel 8
-are created in the
-.Pa /dev/label/
-directory.
-.Pp
-Note that for all label types, nested GEOM classes will cause additional
-device nodes to be created, with context-specific data appended to their
-names. E.g. for every node like
-.Pa /dev/label/bigdisk
-there will be additional entries for any partitions which the device
-contains, like
-.Pa /dev/label/bigdiskp1
-and
-.Pa /dev/label/bigdiskp1a .
-.Pp
-The first argument to
-.Nm
-indicates an action to be performed:
-.Bl -tag -width ".Cm destroy"
-.It Cm create
-Create temporary label
-.Ar name
-for the given provider.
-This is the
-.Dq manual
-method.
-The kernel module
-.Pa geom_label.ko
-will be loaded if it is not loaded already.
-.It Cm label
-Set up a label
-.Ar name
-for the given provider.
-This is the
-.Dq automatic
-method, where metadata is stored in a provider's last sector.
-The kernel module
-.Pa geom_label.ko
-will be loaded if it is not loaded already.
-.It Cm stop
-Turn off the given label by its
-.Ar name .
-This command does not touch on-disk metadata!
-.It Cm destroy
-Same as
-.Cm stop .
-.It Cm clear
-Clear metadata on the given devices.
-.It Cm dump
-Dump metadata stored on the given devices.
-.It Cm refresh
-Refresh / rediscover metadata from the given devices.
-.It Cm list
-See
-.Xr geom 8 .
-.It Cm status
-See
-.Xr geom 8 .
-.It Cm load
-See
-.Xr geom 8 .
-.It Cm unload
-See
-.Xr geom 8 .
-.El
-.Pp
-Additional options:
-.Bl -tag -width indent
-.It Fl f
-Force the removal of the specified labels.
-.It Fl v
-Be more verbose.
-.El
-.Sh SYSCTL VARIABLES
-The following
-.Xr sysctl 8
-variables can be used to control the behavior of the
-.Nm LABEL
-GEOM class.
-The default value is shown next to each variable.
-.Bl -tag -width indent
-.It Va kern.geom.label.debug : No 0
-Debug level of the
-.Nm LABEL
-GEOM class.
-This can be set to a number between 0 and 2 inclusive.
-If set to 0 minimal debug information is printed, and if set to 2 the
-maximum amount of debug information is printed.
-.El
-.Bl -tag -width indent
-.It Va kern.geom.label.*.enable : No 1
-Most
-.Nm LABEL
-providers implement a
-.Xr sysctl 8
-flag and a tunable variable named in the above format. This flag
-controls if the label provider will be active, tasting devices
-and creating label nodes in the
-.Xr devfs 5
-tree. It is sometimes desirable to disable certain label types if
-they conflict with other classes in complex GEOM topologies.
-.El
-.Sh EXIT STATUS
-Exit status is 0 on success, and 1 if the command fails.
-.Sh EXAMPLES
-The following example shows how to set up a label for disk
-.Dq Li da2 ,
-create a file system on it, and mount it:
-.Bd -literal -offset indent
-glabel label -v usr /dev/da2
-newfs /dev/label/usr
-mount /dev/label/usr /usr
-[...]
-umount /usr
-glabel stop usr
-glabel unload
-.Ed
-.Pp
-The next example shows how to set up a label for a UFS file system:
-.Bd -literal -offset indent
-tunefs -L data /dev/da4s1a
-mount /dev/ufs/data /mnt/data
-.Ed
-.Sh SEE ALSO

-.Xr loader.conf 5 ,
-.Xr geom 8 ,
-.Xr mount 8 ,
-.Xr newfs 8 ,
-.Xr sysctl 8 ,
-.Xr tunefs 8 ,

-.Nm
-utility appeared in

-.Sh DESCRIPTION
-The
-.Nm
-utility is used for mirror (RAID1) configurations.
-After a mirror's creation, all components are detected and configured
-automatically.
-All operations like failure detection, stale component detection, rebuild
-of stale components, etc.\& are also done automatically.
-The
-.Nm
-utility uses on-disk metadata (stored in the provider's last sector) to store all needed
-information.
-Since the last sector is used for this purpose, it is possible to place a root
-file system on a mirror.
-.Pp
-The first argument to
-.Nm
-indicates an action to be performed:
-.Bl -tag -width ".Cm deactivate"
-.It Cm label
-Create a mirror.
-The order of components is important, because a component's priority is based on its position
-(starting from 0 to 255).
-The component with the biggest priority is used by the
-.Cm prefer
-balance algorithm
-and is also used as a master component when resynchronization is needed,
-e.g.\& after a power failure when the device was open for writing.
-.Pp
-Additional options include:
-.Bl -tag -width ".Fl b Ar balance"
-.It Fl b Ar balance
-Specifies balance algorithm to use, one of:
-.Bl -tag -width ".Cm round-robin"
-.It Cm load
-Read from the component with the lowest load.
-This is the default balance algorithm.
-.It Cm prefer
-Read from the component with the biggest priority.
-.It Cm round-robin
-Use round-robin algorithm when choosing component to read.
-.It Cm split
-Split read requests, which are bigger than or equal to slice size on N pieces,
-where N is the number of active components.
-.El
-.It Fl F
-Do not synchronize after a power failure or system crash.
-Assumes device is in consistent state.
-.It Fl h
-Hardcode providers' names in metadata.
-.It Fl n
-Turn off autosynchronization of stale components.
-.It Fl s Ar slice
-When using the
-.Cm split
-balance algorithm and an I/O READ request is bigger than or equal to this value,
-the I/O request will be split into N pieces, where N is the number of active
-components.
-Defaults to 4096 bytes.
-.El
-.It Cm clear
-Clear metadata on the given providers.
-.It Cm create
-Similar to
-.Cm label ,
-but creates mirror without storing on-disk metadata in last sector.
-This special "manual" operation mode assumes some external control to manage
-mirror detection after reboot, device hot-plug and other external events.
-.It Cm configure
-Configure the given device.
-.Pp
-Additional options include:
-.Bl -tag -width ".Fl p Ar priority"
-.It Fl a
-Turn on autosynchronization of stale components.
-.It Fl b Ar balance
-Specifies balance algorithm to use.
-.It Fl d
-Do not hardcode providers' names in metadata.
-.It Fl f
-Synchronize device after a power failure or system crash.
-.It Fl F
-Do not synchronize after a power failure or system crash.
-Assumes device is in consistent state.
-.It Fl h
-Hardcode providers' names in metadata.
-.It Fl n
-Turn off autosynchronization of stale components.
-.It Fl p Ar priority
-Specifies priority for the given component
-.Ar prov .
-.It Fl s Ar slice
-Specifies slice size for
-.Cm split
-balance algorithm.
-.El
-.It Cm rebuild
-Rebuild the given mirror components forcibly.
-If autosynchronization was not turned off for the given device, this command
-should be unnecessary.
-.It Cm resize
-Change the size of the given mirror.
-.Pp
-Additional options include:
-.Bl -tag -width ".Fl s Ar size"
-.It Fl s Ar size
-New size of the mirror is expressed in logical block numbers.
-This option can be omitted, then it will be automatically calculated to
-maximum available size.
-.El
-.It Cm insert
-Add the given component(s) to the existing mirror.
-.Pp
-Additional options include:
-.Bl -tag -width ".Fl p Ar priority"
-.It Fl h
-Hardcode providers' names in metadata.
-.It Fl i
-Mark component(s) as inactive immediately after insertion.
-.It Fl p Ar priority
-Specifies priority of the given component(s).
-.El
-.It Cm remove
-Remove the given component(s) from the mirror and clear metadata on it.
-.It Cm activate
-Activate the given component(s), which were marked as inactive before.
-.It Cm deactivate
-Mark the given component(s) as inactive, so it will not be automatically
-connected to the mirror.
-.It Cm destroy
-Stop the given mirror and clear metadata on all its components.
-.Pp
-Additional options include:
-.Bl -tag -width ".Fl f"
-.It Fl f
-Stop the given mirror even if it is opened.
-.El
-.It Cm forget
-Forget about components which are not connected.
-This command is useful when a disk has failed and cannot be reconnected, preventing the
-.Cm remove
-command from being used to remove it.
-.It Cm stop
-Stop the given mirror.
-.Pp
-Additional options include:
-.Bl -tag -width ".Fl f"
-.It Fl f
-Stop the given mirror even if it is opened.
-.El
-.It Cm dump
-Dump metadata stored on the given providers.
-.It Cm list

-.El
-.Pp
-Additional options include:
-.Bl -tag -width ".Fl v"
-.It Fl v
-Be more verbose.
-.El
-.Sh EXIT STATUS
-Exit status is 0 on success, and 1 if the command fails.
-.Sh EXAMPLES
-Use 3 disks to setup a mirror.
-Choose split balance algorithm, split only
-requests which are bigger than or equal to 2kB.
-Create file system,
-mount it, then unmount it and stop device:
-.Bd -literal -offset indent
-gmirror label -v -b split -s 2048 data da0 da1 da2
-newfs /dev/mirror/data
-mount /dev/mirror/data /mnt
-\&...
-umount /mnt
-gmirror stop data
-gmirror unload
-.Ed
-.Pp
-Create a mirror on disk with valid data (note that the last sector of the disk
-will be overwritten).
-Add another disk to this mirror,
-so it will be synchronized with existing disk:
-.Bd -literal -offset indent
-gmirror label -v -b round-robin data da0
-gmirror insert data da1
-.Ed
-.Pp
-Create a mirror, but do not use automatic synchronization feature.
-Add another disk and rebuild it:
-.Bd -literal -offset indent
-gmirror label -v -n -b load data da0 da1
-gmirror insert data da2
-gmirror rebuild data da2
-.Ed
-.Pp
-One disk failed.
-Replace it with a brand new one:
-.Bd -literal -offset indent
-gmirror forget data
-gmirror insert data da1
-.Ed
-.Pp
-Create a mirror, deactivate one component, do the backup and connect it again.
-It will not be resynchronized, if there is no need to do so (there were no writes in
-the meantime):
-.Bd -literal -offset indent
-gmirror label data da0 da1
-gmirror deactivate data da1
-dd if=/dev/da1 of=/backup/data.img bs=1m
-gmirror activate data da1
-.Ed
-.Sh SYSCTL VARIABLES
-The following
-.Xr sysctl 8
-variables can be used to configure behavior for all mirrors.
-.Bl -tag -width indent
-.It Va kern.geom.mirror.debug
-Control the verbosity of kernel logging related to mirrors.
-A value larger than 0 will enable debug logging.
-.It Va kern.geom.mirror.timeout
-The amount of time, in seconds, to wait for all copies of a mirror to
-appear before starting the mirror.
-Disks that appear after the mirror has been started are not automatically
-added to the mirror.
-.It Va kern.geom.mirror.idletime
-The amount of time, in seconds, which must elapse after the last write to
-a mirror before that mirror is marked clean.
-Clean mirrors do not need to be synchronized after a power failure or
-system crash.
-A small value may result in frequent overwrites of the disks' metadata
-sectors, and thus may reduce the longevity of the disks.
-.It Va kern.geom.mirror.disconnect_on_failure
-Determine whether a disk is automatically removed from its mirror when an
-I/O request to that disk fails.
-.It Va kern.geom.mirror.sync_requests
-The number of parallel I/O requests used while synchronizing a mirror.
-This parameter may only be configured as a
-.Xr loader.conf 5
-tunable.
-.It Va kern.geom.mirror.sync_update_period
-The period, in seconds, at which a synchronizing mirror's metadata is
-updated.
-Periodic updates are used to record a synchronization's progress so that
-an interrupted synchronization may be resumed starting at the recorded
-offset, rather than at the beginning.
-A smaller value results in more accurate progress tracking, but also
-increases the number of non-sequential writes to the disk being synchronized.
-If the sysctl value is 0, no updates are performed until the synchronization
-is complete.
-.El
-.Sh NOTES
-Doing kernel dumps to
-.Nm
-providers is possible, but some conditions have to be met.
-First of all, a kernel dump will go only to one component and
-.Nm
-always chooses the component with the highest priority.
-Reading a dump from the mirror on boot will only work if the
-.Cm prefer
-balance algorithm is used (that way
-.Nm
-will read only from the component with the highest priority).
-If you use a different balance algorithm, you should add:
-.Bd -literal -offset indent
-gmirror configure -b prefer data
-.Ed
-.Pp
-to the
-.Pa /etc/rc.early
-script and:
-.Bd -literal -offset indent
-gmirror configure -b round-robin data
-.Ed
-.Pp
-to the
-.Pa /etc/rc.local
-script.
-The decision which component to choose for dumping is made when
-.Xr dumpon 8
-is called.
-If on the next boot a component with a higher priority will be available,
-the prefer algorithm will choose to read from it and
-.Xr savecore 8
-will find nothing.
-If on the next boot a component with the highest priority will be synchronized,
-the prefer balance algorithm will read from the next one, thus will find nothing
-there.

-.Sh DESCRIPTION
-The
-.Nm
-utility is used to control the mount verification GEOM class.
-When configured, it passes all the I/O requests to the underlying provider.
-When the underlying provider disappears - for example because the disk device
-got disconnected - it queues all the I/O requests and waits for the provider
-to reappear.
-When that happens, it attaches to it and sends the queued requests.
-.Pp
-The first argument to
-.Nm
-indicates an action to be performed:
-.Bl -tag -width ".Cm destroy"
-.It Cm create
-Enable mount verification for the given provider.
-If the operation succeeds, a new GEOM provider will be created using the
-given provider's name with a
-.Ql .mountver

-.Sh DESCRIPTION
-The
-.Nm
-utility is used for device multipath configuration.
-.Pp
-The multipath device can be configured using two different methods:
-.Dq manual
-or
-.Dq automatic .
-When using the
-.Dq manual
-method, no metadata are stored on the devices, so the multipath
-device has to be configured by hand every time it is needed.
-Additional device paths also will not be detected automatically.
-The
-.Dq automatic
-method uses on-disk metadata to detect device and all its paths.
-Metadata use the last sector of the underlying disk device and
-include device name and UUID.
-The UUID guarantees uniqueness in a shared storage environment
-but is in general too cumbersome to use.
-The name is what is exported via the device interface.
-.Pp
-The first argument to
-.Nm
-indicates an action to be performed:
-.Bl -tag -width ".Cm destroy"
-.It Cm create
-Create multipath device with
-.Dq manual
-method without writing any on-disk metadata.
-It is up to administrator, how to properly identify device paths.
-Kernel will only check that all given providers have same media and
-sector sizes.
-.Pp
-.Fl A
-option enables Active/Active mode,
-.Fl R
-option enables Active/Read mode, otherwise Active/Passive mode is used
-by default.
-.It Cm label
-Create multipath device with
-.Dq automatic
-method.
-Label the first given provider with on-disk metadata using the specified
-.Ar name .
-The rest of given providers will be retasted to detect these metadata.
-It reliably protects against specifying unrelated providers.
-Providers with no matching metadata detected will not be added to the device.
-.Pp
-.Fl A
-option enables Active/Active mode,
-.Fl R
-option enables Active/Read mode, otherwise Active/Passive mode is used
-by default.
-.It Cm configure
-Configure the given multipath device.
-.Pp
-.Fl A
-option enables Active/Active mode,
-.Fl P
-option enables Active/Passive mode,
-.Fl R
-option enables Active/Read mode.
-.It Cm add
-Add the given provider as a path to the given multipath device.
-Should normally be used only for devices created with
-.Dq manual
-method, unless you know what you are doing (you are sure that it is another
-device path, but tasting its metadata in regular
-.Dq automatic
-way is not possible).
-.It Cm remove
-Remove the given provider as a path from the given multipath device.
-If the last path removed, the multipath device will be destroyed.
-.It Cm fail
-Mark specified provider as a path of the specified multipath device as failed.
-If there are other paths present, new requests will be forwarded there.
-.It Cm restore
-Mark specified provider as a path of the specified multipath device as
-operational, allowing it to handle requests.
-.It Cm rotate
-Change the active provider/path to the next available provider in Active/Passive mode.
-.It Cm prefer
-Change the active provider/path to the specified provider in Active/Passive mode.
-.It Cm getactive
-Get the currently active provider(s)/path(s).
-.It Cm destroy
-Destroy the given multipath device clearing metadata.
-.It Cm stop
-Stop the given multipath device without clearing metadata.
-.It Cm clear
-Clear metadata on the given provider.

-.El
-.Sh SYSCTL VARIABLES
-The following
-.Xr sysctl 8
-variable can be used to control the behavior of the
-.Nm MULTIPATH
-GEOM class.
-.Bl -tag -width indent
-.It Va kern.geom.multipath.debug : No 0
-Debug level of the
-.Nm MULTIPATH
-GEOM class.
-This can be set to 0 (default) or 1 to disable or enable various
-forms of chattiness.
-.It Va kern.geom.multipath.exclusive : No 1
-Open underlying providers exclusively, preventing individual paths access.
-.El
-.Sh EXIT STATUS
-Exit status is 0 on success, and 1 if the command fails.
-.Sh MULTIPATH ARCHITECTURE
-This is a multiple path architecture with no device knowledge or
-presumptions other than size matching built in.
-Therefore the user must exercise some care
-in selecting providers that do indeed represent multiple paths to the
-same underlying disk device.
-The reason for this is that there are several
-criteria across multiple underlying transport types that can
-.Ar indicate
-identity, but in all respects such identity can rarely be considered
-.Ar definitive .
-.Pp
-For example, if you use the World Word Port Name of a Fibre Channel
-disk object you might believe that two disks that have the same WWPN
-on different paths (or even disjoint fabrics) might be considered
-the same disk.
-Nearly always this would be a safe assumption, until
-you realize that a WWPN, like an Ethernet MAC address, is a soft
-programmable entity, and that a misconfigured Director Class switch
-could lead you to believe incorrectly that you have found multiple
-paths to the same device.
-This is an extreme and theoretical case, but
-it is possible enough to indicate that the policy for deciding which
-of multiple pathnames refer to the same device should be left to the
-system operator who will use tools and knowledge of their own storage
-subsystem to make the correct configuration selection.
-.Pp
-There are Active/Passive, Active/Read and Active/Active operation modes
-supported.
-In Active/Passive mode only one path has I/O moving on it
-at any point in time.
-This I/O continues until an I/O is returned with
-a generic I/O error or a "Nonexistent Device" error.
-When this occurs, that path is marked FAIL, the next path
-in a list is selected as active and the failed I/O reissued.
-In Active/Active mode all paths not marked FAIL may handle I/O at the same time.
-Requests are distributed between paths to equalize load.
-For capable devices it allows the utilisation of the bandwidth available on all paths.
-In Active/Read mode all paths not marked FAIL may handle reads at the same time,
-but unlike in Active/Active mode only one path handles write requests at any
-point in time; closely following the original write request order if the layer
-above needs it for data consistency (not waiting for requisite write completion
-before sending dependent write).
-.Pp
-When new devices are added to the system the
-.Nm MULTIPATH
-GEOM class is given an opportunity to taste these new devices.
-If a new
-device has a
-.Nm MULTIPATH
-on-disk metadata label, the device is either used to create a new
-.Nm MULTIPATH
-GEOM, or added to the list of paths for an existing
-.Nm MULTIPATH
-GEOM.
-.Pp
-It is this mechanism that works reasonably with
-.Xr isp 4
-and
-.Xr mpt 4
-based Fibre Channel disk devices.
-For these devices, when a device disappears
-(due to e.g., a cable pull or power failure to a switch), the device is
-proactively marked as gone and I/O to it failed.
-This causes the
-.Nm MULTIPATH
-failure event just described.
-.Pp
-When Fibre Channel events inform either
-.Xr isp 4
-or
-.Xr mpt 4
-host bus adapters that new devices may have arrived (e.g., the arrival
-of an RSCN event from the Fabric Domain Controller), they can cause
-a rescan to occur and cause the attachment and configuration of any
-(now) new devices to occur, causing the taste event described above.
-.Pp
-This means that this multipath architecture is not a one-shot path
-failover, but can be considered to be steady state as long as failed
-paths are repaired (automatically or otherwise).
-.Pp
-Automatic rescanning is not a requirement.
-Nor is Fibre Channel.
-The
-same failover mechanisms work equally well for traditional "Parallel"
-SCSI but may require manual intervention with
-.Xr camcontrol 8
-to cause the reattachment of repaired device links.
-.Sh EXAMPLES
-The following example shows how to use
-.Xr camcontrol 8
-to find possible multiple path devices and to create a
-.Nm MULTIPATH
-GEOM class for them.
-.Bd -literal -offset indent
-mysys# camcontrol devlist
-<ECNCTX @WESTVILLE > at scbus0 target 0 lun 0 (da0,pass0)
-<ECNCTX @WESTVILLE > at scbus0 target 0 lun 1 (da1,pass1)
-<ECNCTX @WESTVILLE > at scbus1 target 0 lun 0 (da2,pass2)
-<ECNCTX @WESTVILLE > at scbus1 target 0 lun 1 (da3,pass3)

-ECNTX0LUN000000SER10ac0d01
-mysys# camcontrol inquiry da2 -S
-ECNTX0LUN000000SER10ac0d01
-.Ed
-.Pp
-Now that you have used the Serial Number to compare two disk paths
-it is not entirely unreasonable to conclude that these are multiple
-paths to the same device.
-However, only the user who is familiar
-with their storage is qualified to make this judgement.
-.Pp
-You can then use the
-.Nm
-command to label and create a
-.Nm MULTIPATH
-GEOM provider named
-.Ar FRED .
-.Bd -literal -offset indent
-gmultipath label -v FRED /dev/da0 /dev/da2
-disklabel -Brw /dev/multipath/FRED auto
-newfs /dev/multipath/FREDa
-mount /dev/multipath/FREDa /mnt....
-.Ed
-.Pp
-The resultant console output looks something like:
-.Bd -literal -offset indent
-GEOM_MULTIPATH: da0 added to FRED
-GEOM_MULTIPATH: da0 is now active path in FRED
-GEOM_MULTIPATH: da2 added to FRED
-.Ed
-.Pp
-To load the
-.Nm
-module at boot time, add this entry to
-.Pa /boot/loader.conf :
-.Bd -literal -offset ident
-geom_multipath_load="YES"

-.Nm
-.Cm unload
-.Sh DESCRIPTION
-The
-.Nm
-utility is used for setting up transparent providers on existing ones.
-Its main purpose is testing other GEOM classes, as it allows forced provider
-removal and I/O error simulation with a given probability.
-It also gathers statistics on the number of read, write, delete,
-getattr, flush, and other requests, and the number of bytes read and written.
-.Nm
-can also be used as a good starting point for implementing new GEOM
-classes.
-.Pp
-The first argument to
-.Nm
-indicates an action to be performed:
-.Bl -tag -width ".Cm configure"
-.It Cm create
-Set up a transparent provider on the given devices.
-If the operation succeeds, the new provider should appear with name
-.Pa /dev/ Ns Ao Ar dev Ac Ns Pa .nop .
-The kernel module
-.Pa geom_nop.ko
-will be loaded if it is not loaded already.
-.It Cm configure
-Configure existing transparent provider.
-At the moment it is only used for changing failure probability.
-.It Cm destroy
-Turn off the given transparent providers.
-.It Cm reset
-Reset statistics for the given transparent providers.
-.It Cm list
-See
-.Xr geom 8 .
-.It Cm status
-See
-.Xr geom 8 .
-.It Cm load
-See
-.Xr geom 8 .
-.It Cm unload
-See
-.Xr geom 8 .
-.El
-.Pp
-Additional options:
-.Bl -tag -width ".Fl r Ar rfailprob"
-.It Fl e Ar error
-Specifies the error number to return on failure.
-.It Fl f
-Force the removal of the specified provider.
-.It Fl o Ar offset
-Where to begin on the original provider.
-.It Fl p Ar stripesize
-Value of the stripesize property of the transparent provider.
-.It Fl P Ar stripeoffset
-Value of the stripeoffset property of the transparent provider.
-.It Fl r Ar rfailprob
-Specifies read failure probability in percent.
-.It Fl s Ar size
-Size of the transparent provider.
-.It Fl S Ar secsize
-Sector size of the transparent provider.
-.It Fl w Ar wfailprob
-Specifies write failure probability in percent.
-.It Fl v
-Be more verbose.
-.It Fl z Ar physpath
-Physical path of the transparent provider.
-.El
-.Sh SYSCTL VARIABLES
-The following
-.Xr sysctl 8
-variables can be used to control the behavior of the
-.Nm NOP
-GEOM class.
-The default value is shown next to each variable.
-.Bl -tag -width indent
-.It Va kern.geom.nop.debug : No 0
-Debug level of the
-.Nm NOP
-GEOM class.
-This can be set to a number between 0 and 2 inclusive.
-If set to 0, minimal debug information is printed.
-If set to 1, basic debug information is logged along with the I/O requests
-that were returned as errors.
-If set to 2, the maximum amount of debug information is printed including
-all I/O requests.
-.El
-.Sh EXIT STATUS
-Exit status is 0 on success, and 1 if the command fails.
-.Sh EXAMPLES
-The following example shows how to create a transparent provider for disk
-.Pa /dev/da0
-with 50% write failure probability, and how to destroy it.
-.Bd -literal -offset indent
-gnop create -v -w 50 da0
-gnop destroy -v da0.nop
-.Ed
-.Pp
-The traffic statistics for the given transparent providers can be obtained
-with the
-.Cm list
-command.
-The example below shows the number of bytes written with
-.Xr newfs 8 :
-.Bd -literal -offset indent
-gnop create da0
-newfs /dev/da0.nop
-gnop list
-.Ed
-.Sh SEE ALSO

-.Sh DESCRIPTION
-The
-.Nm
-utility is used to partition GEOM providers, normally disks.
-The first argument is the action to be taken:
-.Bl -tag -width ".Cm bootcode"
-.\" ==== ADD ====
-.It Cm add
-Add a new partition to the partitioning scheme given by
-.Ar geom .
-The partition type must be specified with
-.Fl t Ar type .
-The partition's location, size, and other attributes will be calculated
-automatically if the corresponding options are not specified.
-.Pp
-The
-.Cm add
-command accepts these options:
-.Bl -tag -width 12n
-.It Fl a Ar alignment
-If specified, then
-.Nm
-utility tries to align
-.Ar start
-offset and partition
-.Ar size
-to be multiple of
-.Ar alignment
-value.
-.It Fl b Ar start
-The logical block address where the partition will begin.
-A SI unit suffix is allowed.
-.It Fl f Ar flags
-Additional operational flags.
-See the section entitled
-.Sx "OPERATIONAL FLAGS"
-below for a discussion
-about its use.
-.It Fl i Ar index
-The index in the partition table at which the new partition is to be
-placed.
-The index determines the name of the device special file used
-to represent the partition.
-.It Fl l Ar label
-The label attached to the partition.
-This option is only valid when used on partitioning schemes that support
-partition labels.
-.It Fl s Ar size
-Create a partition of size
-.Ar size .

-.Sh PARTITIONING SCHEMES
-Several partitioning schemes are supported by the
-.Nm
-utility:
-.Bl -tag -width ".Cm VTOC8"
-.It Cm APM
-Apple Partition Map, used by PowerPC(R) Macintosh(R) computers.
-Requires the
-.Cd GEOM_PART_APM
-kernel option.
-.It Cm BSD
-Traditional BSD disklabel, usually used to subdivide MBR partitions.
-.Po
-This scheme can also be used as the sole partitioning method, without
-an MBR.
-Partition editing tools from other operating systems often do not
-understand the bare disklabel partition layout, so this is sometimes
-called
-.Dq dangerously dedicated .
-.Pc
-Requires the
-.Cm GEOM_PART_BSD
-kernel option.
-.It Cm BSD64
-64-bit implementation of BSD disklabel used in DragonFlyBSD to subdivide MBR
-or GPT partitions.
-Requires the
-.Cm GEOM_PART_BSD64
-kernel option.
-.It Cm LDM
-The Logical Disk Manager is an implementation of volume manager for
-Microsoft Windows NT.
-Requires the
-.Cd GEOM_PART_LDM
-kernel option.
-.It Cm GPT
-GUID Partition Table is used on Intel-based Macintosh computers and
-gradually replacing MBR on most PCs and other systems.
-Requires the
-.Cm GEOM_PART_GPT
-kernel option.
-.It Cm MBR
-Master Boot Record is used on PCs and removable media.
-Requires the
-.Cm GEOM_PART_MBR
-kernel option.
-The
-.Cm GEOM_PART_EBR
-option adds support for the Extended Boot Record (EBR),
-which is used to define a logical partition.

-.Sh PARTITION TYPES
-Partition types are identified on disk by particular strings or magic
-values.
-The
-.Nm
-utility uses symbolic names for common partition types so the user
-does not need to know these values or other details of the partitioning
-scheme in question.
-The
-.Nm
-utility also allows the user to specify scheme-specific partition types
-for partition types that do not have symbolic names.

-.It Cm bootonce
-Setting this attribute automatically sets the

-.Sh BOOTSTRAPPING
-.Fx
-supports several partitioning schemes and each scheme uses different
-bootstrap code.
-The bootstrap code is located in a specific disk area for each partitioning
-scheme, and may vary in size for different schemes.
-.Pp
-Bootstrap code can be separated into two types.
-The first type is embedded in the partitioning scheme's metadata, while the
-second type is located on a specific partition.
-Embedding bootstrap code should only be done with the
-.Cm gpart bootcode
-command with the
-.Fl b Ar bootcode
-option.
-The GEOM PART class knows how to safely embed bootstrap code into
-specific partitioning scheme metadata without causing any damage.
-.Pp
-The Master Boot Record (MBR) uses a 512-byte bootstrap code image, embedded
-into the partition table's metadata area.
-There are two variants of this bootstrap code:
-.Pa /boot/mbr
-and
-.Pa /boot/boot0 .
-.Pa /boot/mbr
-searches for a partition with the
-.Cm active
-attribute (see the
-.Sx ATTRIBUTES
-section) in the partition table.
-Then it runs next bootstrap stage.
-The
-.Pa /boot/boot0
-image contains a boot manager with some additional interactive functions
-for multi-booting from a user-selected partition.
-.Pp
-A BSD disklabel is usually created inside an MBR partition (slice)
-with type
-.Cm freebsd
-(see the
-.Sx "PARTITION TYPES"
-section).
-It uses 8 KB size bootstrap code image
-.Pa /boot/boot ,
-embedded into the partition table's metadata area.
-.Pp
-Both types of bootstrap code are used to boot from the GUID Partition Table.
-First, a protective MBR is embedded into the first disk sector from the
-.Pa /boot/pmbr
-image.
-It searches through the GPT for a
-.Cm freebsd-boot
-partition (see the
-.Sx "PARTITION TYPES"
-section) and runs the next bootstrap stage from it.
-The
-.Cm freebsd-boot
-partition should be smaller than 545 KB.
-It can be located either before or after other
-.Fx
-partitions on the disk.
-There are two variants of bootstrap code to write to this partition:
-.Pa /boot/gptboot
-and
-.Pa /boot/gptzfsboot .
-.Pp
-.Pa /boot/gptboot
-is used to boot from UFS partitions.
-.Cm gptboot
-searches through
-.Cm freebsd-ufs
-partitions in the GPT and selects one to boot based on the
-.Cm bootonce
-and
-.Cm bootme
-attributes.
-If neither attribute is found,
-.Pa /boot/gptboot
-boots from the first
-.Cm freebsd-ufs
-partition.
-.Pa /boot/loader
-.Pq the third bootstrap stage
-is loaded from the first partition that matches these conditions.
-See
-.Xr gptboot 8
-for more information.
-.Pp
-.Pa /boot/gptzfsboot
-is used to boot from ZFS.
-It searches through the GPT for
-.Cm freebsd-zfs
-partitions, trying to detect ZFS pools.
-After all pools are detected,
-.Pa /boot/zfsloader
-is started from the first one found.
-.Pp
-The VTOC8 scheme does not support embedding bootstrap code.
-Instead, the 8 KBytes bootstrap code image
-.Pa /boot/boot1
-should be written with the
-.Cm gpart bootcode
-command with the
-.Fl p Ar bootcode
-option to all sufficiently large VTOC8 partitions.
-To do this the
-.Fl i Ar index
-option could be omitted.
-.Pp
-The APM scheme also does not support embedding bootstrap code.
-Instead, the 800 KBytes bootstrap code image
-.Pa /boot/boot1.hfs
-should be written with the
-.Cm gpart bootcode
-command to a partition of type
-.Cm apple-boot ,
-which should also be 800 KB in size.
-.Sh OPERATIONAL FLAGS
-Actions other than the
-.Cm commit
-and
-.Cm undo
-actions take an optional
-.Fl f Ar flags
-option.
-This option is used to specify action-specific operational flags.
-By default, the
-.Nm
-utility defines the
-.Ql C
-flag so that the action is immediately
-committed.
-The user can specify
-.Dq Fl f Cm x
-to have the action result in a pending change that can later, with
-other pending changes, be committed as a single compound change with
-the
-.Cm commit
-action or reverted with the
-.Cm undo
-action.
-.Sh RECOVERING
-The GEOM PART class supports recovering of partition tables only for GPT.
-The GPT primary metadata is stored at the beginning of the device.
-For redundancy, a secondary
-.Pq backup
-copy of the metadata is stored at the end of the device.
-As a result of having two copies, some corruption of metadata is not
-fatal to the working of GPT.
-When the kernel detects corrupt metadata, it marks this table as corrupt
-and reports the problem.
-.Cm destroy
-and
-.Cm recover
-are the only operations allowed on corrupt tables.
-.Pp
-If one GPT header appears to be corrupt but the other copy remains intact,
-the kernel will log the following:
-.Bd -literal -offset indent
-GEOM: provider: the primary GPT table is corrupt or invalid.
-GEOM: provider: using the secondary instead -- recovery strongly advised.
-.Ed
-.Pp
-or
-.Bd -literal -offset indent
-GEOM: provider: the secondary GPT table is corrupt or invalid.
-GEOM: provider: using the primary only -- recovery suggested.
-.Ed
-.Pp
-Also
-.Nm
-commands such as
-.Cm show , status
-and
-.Cm list
-will report about corrupt tables.
-.Pp
-If the size of the device has changed (e.g.,\& volume expansion) the
-secondary GPT header will no longer be located in the last sector.
-This is not a metadata corruption, but it is dangerous because any
-corruption of the primary GPT will lead to loss of the partition table.
-This problem is reported by the kernel with the message:
-.Bd -literal -offset indent
-GEOM: provider: the secondary GPT header is not in the last LBA.
-.Ed
-.Pp
-This situation can be recovered with the
-.Cm recover
-command.
-This command reconstructs the corrupt metadata using known valid
-metadata and relocates the secondary GPT to the end of the device.
-.Pp
-.Em NOTE :
-The GEOM PART class can detect the same partition table visible through
-different GEOM providers, and some of them will be marked as corrupt.
-Be careful when choosing a provider for recovery.
-If you choose incorrectly you can destroy the metadata of another GEOM class,
-e.g.,\& GEOM MIRROR or GEOM LABEL.
-.Sh SYSCTL VARIABLES
-The following
-.Xr sysctl 8
-variables can be used to control the behavior of the
-.Nm PART
-GEOM class.
-The default value is shown next to each variable.
-.Bl -tag -width indent
-.It Va kern.geom.part.auto_resize: No 1
-This variable controls automatic resize behavior of
-.Nm
-GEOM class.
-When this variable is enable and new size of provider is detected, the schema
-metadata is resized but all changes are not saved to disk, until
-.Cm gpart commit
-is run to confirm changes.
-This behavior is also reported with diagnostic message:
-.Sy "GEOM_PART: (provider) was automatically resized."
-.Sy "Use `gpart commit (provider)` to save changes or `gpart undo (provider)`"
-.Sy "to revert them."
-.It Va kern.geom.part.check_integrity : No 1
-This variable controls the behaviour of metadata integrity checks.
-When integrity checks are enabled, the
-.Nm PART
-GEOM class verifies all generic partition parameters obtained from the
-disk metadata.
-If some inconsistency is detected, the partition table will be
-rejected with a diagnostic message:
-.Sy "GEOM_PART: Integrity check failed (provider, scheme)" .
-.It Va kern.geom.part.ldm.debug : No 0
-Debug level of the Logical Disk Manager (LDM) module.
-This can be set to a number between 0 and 2 inclusive.
-If set to 0 minimal debug information is printed,
-and if set to 2 the maximum amount of debug information is printed.
-.It Va kern.geom.part.ldm.show_mirrors : No 0
-This variable controls how the Logical Disk Manager (LDM) module handles
-mirrored volumes.
-By default mirrored volumes are shown as partitions with type
-.Cm ms-ldm-data
-(see the
-.Sx "PARTITION TYPES"
-section).
-If this variable set to 1 each component of the mirrored volume will be
-present as independent partition.
-.Em NOTE :
-This may break a mirrored volume and lead to data damage.
-.It Va kern.geom.part.mbr.enforce_chs : No 0
-Specify how the Master Boot Record (MBR) module does alignment.
-If this variable is set to a non-zero value, the module will automatically
-recalculate the user-specified offset and size for alignment with the CHS
-geometry.
-Otherwise the values will be left unchanged.

-.Sh EXIT STATUS
-Exit status is 0 on success, and 1 if the command fails.
-.Sh EXAMPLES
-The examples below assume that the disk's logical block size is 512
-bytes, regardless of its physical block size.
-.Ss GPT
-In this example, we will format
-.Pa ada0
-with the GPT scheme and create boot, swap and root partitions.
-First, we need to create the partition table:
-.Bd -literal -offset indent
-/sbin/gpart create -s GPT ada0
-.Ed
-.Pp
-Next, we install a protective MBR with the first-stage bootstrap code.
-The protective MBR lists a single, bootable partition spanning the
-entire disk, thus allowing non-GPT-aware BIOSes to boot from the disk
-and preventing tools which do not understand the GPT scheme from
-considering the disk to be unformatted.
-.Bd -literal -offset indent
-/sbin/gpart bootcode -b /boot/pmbr ada0
-.Ed
-.Pp
-We then create a dedicated
-.Cm freebsd-boot
-partition to hold the second-stage boot loader, which will load the
-.Fx
-kernel and modules from a UFS or ZFS filesystem.
-This partition must be larger than the bootstrap code
-.Po
-either
-.Pa /boot/gptboot
-for UFS or
-.Pa /boot/gptzfsboot
-for ZFS
-.Pc ,
-but smaller than 545 kB since the first-stage loader will load the
-entire partition into memory during boot, regardless of how much data
-it actually contains.
-We create a 472-block (236 kB) boot partition at offset 40, which is
-the size of the partition table (34 blocks or 17 kB) rounded up to the
-nearest 4 kB boundary.
-.Bd -literal -offset indent
-/sbin/gpart add -b 40 -s 472 -t freebsd-boot ada0
-/sbin/gpart bootcode -p /boot/gptboot -i 1 ada0
-.Ed
-.Pp
-We now create a 4 GB swap partition at the first available offset,
-which is 40 + 472 = 512 blocks (256 kB).
-.Bd -literal -offset indent
-/sbin/gpart add -s 4G -t freebsd-swap ada0
-.Ed
-.Pp
-Aligning the swap partition and all subsequent partitions on a 256 kB
-boundary ensures optimal performance on a wide range of media, from
-plain old disks with 512-byte blocks, through modern
-.Dq advanced format
-disks with 4096-byte physical blocks, to RAID volumes with stripe
-sizes of up to 256 kB.
-.Pp
-Finally, we create and format an 8 GB
-.Cm freebsd-ufs
-partition for the root filesystem, leaving the rest of the slice free
-for additional filesystems:
-.Bd -literal -offset indent
-/sbin/gpart add -s 8G -t freebsd-ufs ada0
-/sbin/newfs -Uj /dev/ada0p3
-.Ed
-.Ss MBR
-In this example, we will format
-.Pa ada0
-with the MBR scheme and create a single partition which we subdivide
-using a traditional
-.Bx
-disklabel.
-.Pp
-First, we create the partition table and a single 64 GB partition,
-then we mark that partition active (bootable) and install the
-first-stage boot loader:
-.Bd -literal -offset indent
-/sbin/gpart create -s MBR ada0
-/sbin/gpart add -t freebsd -s 64G ada0
-/sbin/gpart set -a active -i 1 ada0
-/sbin/gpart bootcode -b /boot/boot0 ada0
-.Ed
-.Pp
-Next, we create a disklabel in that partition
-.Po
-.Dq slice
-in disklabel terminology
-.Pc
-with room for up to 20 partitions:
-.Bd -literal -offset indent
-/sbin/gpart create -s BSD -n 20 ada0s1
-.Ed
-.Pp
-We then create an 8 GB root partition and a 4 GB swap partition:
-.Bd -literal -offset indent
-/sbin/gpart add -t freebsd-ufs -s 8G ada0s1
-/sbin/gpart add -t freebsd-swap -s 4G ada0s1
-.Ed
-.Pp
-Finally, we install the appropriate boot loader for the
-.Bx
-label:
-.Bd -literal -offset indent
-/sbin/gpart bootcode -b /boot/boot ada0s1
-.Ed
-.Ss VTOC8
-.Pp
-Create a VTOC8 scheme on
-.Pa da0 :
-.Bd -literal -offset indent
-/sbin/gpart create -s VTOC8 da0
-.Ed
-.Pp
-Create a 512MB-sized
-.Cm freebsd-ufs
-partition to contain a UFS filesystem from which the system can boot.
-.Bd -literal -offset indent
-/sbin/gpart add -s 512M -t freebsd-ufs da0
-.Ed
-.Pp
-Create a 15GB-sized
-.Cm freebsd-ufs
-partition to contain a UFS filesystem and aligned on 4KB boundaries:
-.Bd -literal -offset indent
-/sbin/gpart add -s 15G -t freebsd-ufs -a 4k da0
-.Ed
-.Pp
-After creating all required partitions, embed bootstrap code into them:
-.Bd -literal -offset indent
-/sbin/gpart bootcode -p /boot/boot1 da0
-.Ed
-.Ss Deleting Partitions and Destroying the Partitioning Scheme
-If a
-.Em "Device busy"
-error is shown when trying to destroy a partition table, remember that
-all of the partitions must be deleted first with the
-.Cm delete
-action.
-In this example,
-.Pa da0
-has three partitions:
-.Bd -literal -offset indent
-/sbin/gpart delete -i 3 da0
-/sbin/gpart delete -i 2 da0
-/sbin/gpart delete -i 1 da0
-/sbin/gpart destroy da0
-.Ed
-.Pp
-Rather than deleting each partition and then destroying the partitioning
-scheme, the
-.Fl F
-option can be given with
-.Cm destroy
-to delete all of the partitions before destroying the partitioning scheme.
-This is equivalent to the previous example:
-.Bd -literal -offset indent
-/sbin/gpart destroy -F da0
-.Ed
-.Ss Backup and Restore
-.Pp
-Create a backup of the partition table from
-.Pa da0 :
-.Bd -literal -offset indent
-/sbin/gpart backup da0 > da0.backup
-.Ed
-.Pp
-Restore the partition table from the backup to
-.Pa da0 :
-.Bd -literal -offset indent
-/sbin/gpart restore -l da0 < /mnt/da0.backup
-.Ed
-.Pp
-Clone the partition table from
-.Pa ada0
-to
-.Pa ada1
-and
-.Pa ada2 :
-.Bd -literal -offset indent
-/sbin/gpart backup ada0 | /sbin/gpart restore -F ada1 ada2

-.Sh DESCRIPTION
-The
-.Nm
-utility is used to manage software RAID configurations, supported by the
-GEOM RAID class.
-GEOM RAID class uses on-disk metadata to provide access to software-RAID
-volumes defined by different RAID BIOSes.
-Depending on RAID BIOS type and its metadata format, different subsets of
-configurations and features are supported.
-To allow booting from RAID volume, the metadata format should match the
-RAID BIOS type and its capabilities.
-To guarantee that these match, it is recommended to create volumes via the
-RAID BIOS interface, while experienced users are free to do it using this
-utility.
-.Pp
-The first argument to
-.Nm
-indicates an action to be performed:
-.Bl -tag -width ".Cm destroy"
-.It Cm label
-Create an array with single volume.
-The
-.Ar format
-argument specifies the on-disk metadata format to use for this array,
-such as "Intel".
-The
-.Ar label
-argument specifies the label of the created volume.
-The
-.Ar level
-argument specifies the RAID level of the created volume, such as:
-"RAID0", "RAID1", etc.
-The subsequent list enumerates providers to use as array components.
-The special name "NONE" can be used to reserve space for absent disks.
-The order of components can be important, depending on specific RAID level
-and metadata format.
-.Pp
-Additional options include:
-.Bl -tag -width ".Fl s Ar strip"
-.It Fl f
-Enforce specified configuration creation if it is officially unsupported,
-but technically can be created.
-.It Fl o Ar fmtopt
-Specifies metadata format options.
-.It Fl S Ar size
-Use
-.Ar size
-bytes on each component for this volume.
-Should be used if several volumes per array are planned, or if smaller
-components going to be inserted later.
-Defaults to size of the smallest component.
-.It Fl s Ar strip
-Specifies strip size in bytes.
-Defaults to 131072.
-.El
-.It Cm add
-Create another volume on the existing array.
-The
-.Ar name
-argument is the name of the existing array, reported by label command.
-The rest of arguments are the same as for the label command.
-.It Cm delete
-Delete volume(s) from the existing array.
-When the last volume is deleted, the array is also deleted and its metadata
-erased.
-The
-.Ar name
-argument is the name of existing array.
-Optional
-.Ar label
-or
-.Ar num
-arguments allow specifying volume for deletion.
-.Pp
-Additional options include:
-.Bl -tag -width ".Fl f"
-.It Fl f
-Delete volume(s) even if it is still open.
-.El
-.It Cm insert
-Insert specified provider(s) into specified array instead of the first missing
-or failed components.
-If there are no such components, mark disk(s) as spare.
-.It Cm remove
-Remove the specified provider(s) from the specified array and erase metadata.
-If there are spare disks present, the removed disk(s) will be replaced by
-spares.
-.It Cm fail
-Mark the given disks(s) as failed, removing from active use unless absolutely
-necessary due to exhausted redundancy.
-If there are spare disks present - failed disk(s) will be replaced with one
-of them.
-.It Cm stop
-Stop the given array.
-The metadata will not be erased.
-.Pp
-Additional options include:
-.Bl -tag -width ".Fl f"
-.It Fl f
-Stop the given array even if some of its volumes are opened.
-.El
-.It Cm list
-See
-.Xr geom 8 .
-.It Cm status
-See
-.Xr geom 8 .
-.It Cm load
-See
-.Xr geom 8 .
-.It Cm unload
-See
-.Xr geom 8 .
-.El
-.Pp
-Additional options include:
-.Bl -tag -width ".Fl v"
-.It Fl v
-Be more verbose.
-.El
-.Sh SUPPORTED METADATA FORMATS
-The GEOM RAID class follows a modular design, allowing different metadata
-formats to be used.
-Support is currently implemented for the following formats:
-.Bl -tag -width "Intel"
-.It DDF
-The format defined by the SNIA Common RAID Disk Data Format v2.0 specification.
-Used by some Adaptec RAID BIOSes and some hardware RAID controllers.
-Because of high format flexibility different implementations support
-different set of features and have different on-disk metadata layouts.
-To provide compatibility, the GEOM RAID class mimics capabilities
-of the first detected DDF array.
-Respecting that, it may support different number of disks per volume,
-volumes per array, partitions per disk, etc.
-The following configurations are supported: RAID0 (2+ disks), RAID1 (2+ disks),
-RAID1E (3+ disks), RAID3 (3+ disks), RAID4 (3+ disks), RAID5 (3+ disks),
-RAID5E (4+ disks), RAID5EE (4+ disks), RAID5R (3+ disks), RAID6 (4+ disks),
-RAIDMDF (4+ disks), RAID10 (4+ disks), SINGLE (1 disk), CONCAT (2+ disks).
-.Pp
-Format supports two options "BE" and "LE", that mean big-endian byte order
-defined by specification (default) and little-endian used by some Adaptec
-controllers.
-.It Intel
-The format used by Intel RAID BIOS.
-Supports up to two volumes per array.
-Supports configurations: RAID0 (2+ disks), RAID1 (2 disks),
-RAID5 (3+ disks), RAID10 (4 disks).
-Configurations not supported by Intel RAID BIOS, but enforceable on your own
-risk: RAID1 (3+ disks), RAID1E (3+ disks), RAID10 (6+ disks).
-.It JMicron
-The format used by JMicron RAID BIOS.
-Supports one volume per array.
-Supports configurations: RAID0 (2+ disks), RAID1 (2 disks),
-RAID10 (4 disks), CONCAT (2+ disks).
-Configurations not supported by JMicron RAID BIOS, but enforceable on your own
-risk: RAID1 (3+ disks), RAID1E (3+ disks), RAID10 (6+ disks), RAID5 (3+ disks).
-.It NVIDIA
-The format used by NVIDIA MediaShield RAID BIOS.
-Supports one volume per array.
-Supports configurations: RAID0 (2+ disks), RAID1 (2 disks),
-RAID5 (3+ disks), RAID10 (4+ disks), SINGLE (1 disk), CONCAT (2+ disks).
-Configurations not supported by NVIDIA MediaShield RAID BIOS, but enforceable
-on your own risk: RAID1 (3+ disks).
-.It Promise
-The format used by Promise and AMD/ATI RAID BIOSes.
-Supports multiple volumes per array.
-Each disk can be split to be used by up to two arbitrary volumes.
-Supports configurations: RAID0 (2+ disks), RAID1 (2 disks),
-RAID5 (3+ disks), RAID10 (4 disks), SINGLE (1 disk), CONCAT (2+ disks).
-Configurations not supported by RAID BIOSes, but enforceable on your
-own risk: RAID1 (3+ disks), RAID10 (6+ disks).
-.It SiI
-The format used by SiliconImage RAID BIOS.
-Supports one volume per array.
-Supports configurations: RAID0 (2+ disks), RAID1 (2 disks),
-RAID5 (3+ disks), RAID10 (4 disks), SINGLE (1 disk), CONCAT (2+ disks).
-Configurations not supported by SiliconImage RAID BIOS, but enforceable on your
-own risk: RAID1 (3+ disks), RAID10 (6+ disks).
-.El
-.Sh SUPPORTED RAID LEVELS
-The GEOM RAID class follows a modular design, allowing different RAID levels
-to be used.
-Full support for the following RAID levels is currently implemented:
-RAID0, RAID1, RAID1E, RAID10, SINGLE, CONCAT.
-The following RAID levels supported as read-only for volumes in optimal
-state (without using redundancy): RAID4, RAID5, RAID5E, RAID5EE, RAID5R,
-RAID6, RAIDMDF.
-.Sh RAID LEVEL MIGRATION
-The GEOM RAID class has no support for RAID level migration, allowed by some
-metadata formats.
-If you started migration using BIOS or in some other way, make sure to
-complete it there.
-Do not run GEOM RAID class on migrating volumes under pain of possible data
-corruption!
-.Sh 2TiB BARRIERS
-NVIDIA metadata format does not support volumes above 2TiB.
-.Sh SYSCTL VARIABLES
-The following
-.Xr sysctl 8
-variable can be used to control the behavior of the
-.Nm RAID
-GEOM class.
-.Bl -tag -width indent
-.It Va kern.geom.raid.aggressive_spare : No 0
-Use any disks without metadata connected to controllers of the vendor
-matching to volume metadata format as spare.

-Providers name format: 0 -- raid/r{num}, 1 -- raid/{label}.
-.It Va kern.geom.raid.read_err_thresh : No 10
-Number of read errors equated to disk failure.
-Write errors are always considered as disk failures.
-.It Va kern.geom.raid.start_timeout : No 30
-Time to wait for missing array components on startup.
-.It Va kern.geom.raid. Ns Ar X Ns Va .enable : No 1
-Enable taste for specific metadata or transformation module.

-.Sh DESCRIPTION
-The
-.Nm
-utility is used for RAID3 array configuration.
-After a device is created, all components are detected and configured
-automatically.
-All operations such as failure detection, stale component detection, rebuild
-of stale components, etc.\& are also done automatically.
-The
-.Nm
-utility uses on-disk metadata (the provider's last sector) to store all needed
-information.
-.Pp
-The first argument to
-.Nm
-indicates an action to be performed:
-.Bl -tag -width ".Cm configure"
-.It Cm label
-Create a RAID3 device.
-The last given component will contain parity data, whilst the others
-will all contain regular data.
-The number of components must be equal to 3, 5, 9, 17, etc.\& (2^n + 1).
-.Pp
-Additional options include:
-.Bl -tag -width ".Fl h"
-.It Fl F
-Do not synchronize after a power failure or system crash.
-Assumes device is in consistent state.
-.It Fl h
-Hardcode providers' names in metadata.
-.It Fl n
-Turn off autosynchronization of stale components.
-.It Fl r
-Use parity component for reading in round-robin fashion.
-Without this option the parity component is not used at all for reading operations
-when the device is in a complete state.
-With this option specified random I/O read operations are even 40% faster,
-but sequential reads are slower.
-One cannot use this option if the
-.Fl w
-option is also specified.
-.It Fl s
-Manually specify array block size. Block size will be set equal to least
-common multiple of all component's sector sizes and specified value.
-Note that array sector size calculated as multiple of block size and number
-of regular data components. Big values may decrease performance and compatibility,
-as all I/O requests have to be multiple of sector size.
-.It Fl w
-Use verify reading feature.
-When reading from a device in a complete state, also read data from the parity component
-and verify the data by comparing XORed regular data with parity data.
-If verification fails, an
-.Er EIO
-error is returned and the value of the
-.Va kern.geom.raid3.stat.parity_mismatch
-sysctl is increased.
-One cannot use this option if the
-.Fl r
-option is also specified.
-.El
-.It Cm clear
-Clear metadata on the given providers.
-.It Cm configure
-Configure the given device.
-.Pp
-Additional options include:
-.Bl -tag -width ".Fl a"
-.It Fl a
-Turn on autosynchronization of stale components.
-.It Fl d
-Do not hardcode providers' names in metadata.
-.It Fl f
-Synchronize device after a power failure or system crash.
-.It Fl F
-Do not synchronize after a power failure or system crash.
-Assumes device is in consistent state.
-.It Fl h
-Hardcode providers' names in metadata.
-.It Fl n
-Turn off autosynchronization of stale components.
-.It Fl r
-Turn on round-robin reading.
-.It Fl R
-Turn off round-robin reading.
-.It Fl w
-Turn on verify reading.
-.It Fl W
-Turn off verify reading.
-.El
-.It Cm rebuild
-Rebuild the given component forcibly.
-If autosynchronization was not turned off for the given device, this command
-should be unnecessary.
-.It Cm insert
-Add the given component to the existing array, if one of the components was
-removed previously with the
-.Cm remove
-command or if one component is missing and will not be connected again.
-If no number is given, new component will be added instead of first missed
-component.
-.Pp
-Additional options include:
-.Bl -tag -width ".Fl h"
-.It Fl h
-Hardcode providers' names in metadata.
-.El
-.It Cm remove
-Remove the given component from the given array and clear metadata on it.
-.It Cm stop
-Stop the given arrays.
-.Pp
-Additional options include:
-.Bl -tag -width ".Fl f"
-.It Fl f
-Stop the given array even if it is opened.
-.El
-.It Cm list
-See
-.Xr geom 8 .
-.It Cm status
-See
-.Xr geom 8 .
-.It Cm load
-See
-.Xr geom 8 .
-.It Cm unload
-See
-.Xr geom 8 .
-.El
-.Pp
-Additional options include:
-.Bl -tag -width ".Fl v"
-.It Fl v
-Be more verbose.
-.El
-.Sh EXIT STATUS
-Exit status is 0 on success, and 1 if the command fails.
-.Sh EXAMPLES
-Use 3 disks to setup a RAID3 array (with the round-robin reading feature).
-Create a file system, mount it, then unmount it and stop device:
-.Bd -literal -offset indent
-graid3 label -v -r data da0 da1 da2
-newfs /dev/raid3/data
-mount /dev/raid3/data /mnt
-\&...
-umount /mnt
-graid3 stop data
-graid3 unload
-.Ed
-.Pp
-Create a RAID3 array, but do not use the automatic synchronization feature.
-Rebuild parity component:
-.Bd -literal -offset indent
-graid3 label -n data da0 da1 da2
-graid3 rebuild data da2
-.Ed
-.Pp
-Replace one data disk with a brand new one:
-.Bd -literal -offset indent
-graid3 remove -n 0 data
-graid3 insert -n 0 data da5

-.Nm
-.Cm { list | status | load | unload }
-.Sh DESCRIPTION
-The
-.Nm
-utility (also callable as
-.Nm geom sched ... )
-changes the scheduling policy of the requests going to a provider.
-.Pp
-The first argument to
-.Nm
-indicates an action to be performed:
-.Bl -tag -width ".Cm configure"
-.It Cm create
-Create a new provider and geom node using the specified scheduling algorithm.
-.Ar algorithm
-is the name of the scheduling algorithm used for the provider.
-Available algorithms include:
-.Ar rr ,
-which implements anticipatory scheduling with round robin service
-among clients;
-.Ar as ,
-which implements a simple form of anticipatory scheduling with
-no per-client queue.
-.Pp
-If the operation succeeds, the new provider should appear with name
-.Pa /dev/ Ns Ao Ar dev Ac Ns Pa .sched. .
-The kernel module
-.Pa geom_sched.ko
-will be loaded if it is not loaded already.
-.It Cm insert
-Operates as "create", but the insertion is "transparent",
-i.e. the existing provider is rerouted to the newly created geom,
-which in turn forwards requests to the existing geom.
-This operation allows one to start/stop a scheduling service
-on an already existing provider.
-.Pp
-A subsequent "destroy" will remove the newly created geom and
-hook the provider back to the original geom.
-.It Cm configure
-Configure existing scheduling provider. It supports the same options
-as the
-.Nm create
-command.
-.It Cm destroy
-Destroy the geom specified in the parameter.
-.It Cm reset
-Do nothing.
-.It Cm list | status | load | unload
-See
-.Xr geom 8 .
-.El
-.Pp
-Additional options:
-.Bl -tag -width ".Fl f"
-.It Fl f
-Force the removal of the specified provider.
-.It Fl v
-Be more verbose.
-.El
-.Sh SYSCTL VARIABLES
-The following
-.Xr sysctl 8
-variables can be used to control the behavior of the
-.Nm SCHED
-GEOM class.
-The default value is shown next to each variable.
-.Bl -tag -width indent
-.It Va kern.geom.sched.debug : No 0
-Debug level of the
-.Nm SCHED
-GEOM class.
-This can be set to a number between 0 and 2 inclusive.
-If set to 0 minimal debug information is printed, and if set to 2 the
-maximum amount of debug information is printed.
-.El
-.Sh EXIT STATUS
-Exit status is 0 on success, and 1 if the command fails.
-.Sh EXAMPLES
-The following example shows how to create a scheduling provider for disk
-.Pa /dev/ada0 ,
-and how to destroy it.
-.Bd -literal -offset indent
-# Load the geom_sched module:
-kldload geom_sched
-# Load some scheduler classes used by geom_sched:
-kldload gsched_rr
-# Configure device ada0 to use scheduler "rr":
-geom sched insert -a rr ada0
-# Now provider ada0 uses the "rr" algorithm;
-# the new geom is ada0.sched.
-# Remove the scheduler on the device:
-geom sched destroy -v ada0.sched.
-.Ed
-.Sh SEE ALSO
-.Xr geom 4 ,
-.Xr geom 8
-.Sh HISTORY
-The
-.Nm
-utility first appeared in
-.Fx 8.1 .

-.Sh DESCRIPTION
-The
-.Nm
-utility is used for setting up a device which contains a shared secret.
-The secret is shared between the given providers.
-To collect the secret, all providers are needed.
-If one of the components is missing, there is no way to get any useful data from
-the rest of them.
-The first argument to
-.Nm
-indicates an action to be performed:
-.Bl -tag -width ".Cm destroy"
-.It Cm label
-Set up a shared secret device from the given components with the specified
-.Ar name .
-Metadata are stored in the last sector of every component.
-.It Cm stop
-Turn off an existing shared secret device by its
-.Ar name .
-This command does not touch on-disk metadata!
-.It Cm clear
-Clear metadata on the given providers.
-.It Cm dump
-Dump metadata stored on the given providers.
-.It Cm list
-See
-.Xr geom 8 .
-.It Cm status
-See
-.Xr geom 8 .
-.It Cm load
-See

-.El
-.Pp
-Additional options:
-.Bl -tag -width ".Fl f"
-.It Fl f
-Force the removal of the specified shared secret device.
-.It Fl h
-Hardcode providers' names in metadata.
-.It Fl v
-Be more verbose.
-.El
-.Sh EXIT STATUS
-Exit status is 0 on success, and 1 if the command fails.
-.Sh EXAMPLES
-The following example shows how to create a shared secret device.
-The secret will be split between a slice on a local disk and a USB Pen drive.
-.Bd -literal -offset indent
-gshsec label -v secret /dev/ada0s1 /dev/da0
-newfs /dev/shsec/secret

-.Cm list
-.Nm
-.Cm status
-.Nm
-.Cm load
-.Nm
-.Cm unload
-.Sh DESCRIPTION
-The
-.Nm
-utility is used for setting up a stripe on two or more disks.
-The striped device can be configured using two different methods:
-.Dq manual
-or
-.Dq automatic .
-When using the
-.Dq manual
-method, no metadata are stored on the devices, so the striped
-device has to be configured by hand every time it is needed.
-The
-.Dq automatic
-method uses on-disk metadata to detect devices.
-Once devices are labeled, they will be automatically detected and
-configured.
-.Pp
-The first argument to
-.Nm
-indicates an action to be performed:
-.Bl -tag -width ".Cm destroy"
-.It Cm create
-Set up a striped device from the given devices with specified
-.Ar name .
-This is the
-.Dq manual
-method and the stripe will not exist after a reboot (see
-.Sx DESCRIPTION
-above).
-The kernel module
-.Pa geom_stripe.ko
-will be loaded if it is not loaded already.
-.It Cm label
-Set up a striped device from the given devices with the specified
-.Ar name .
-This is the
-.Dq automatic
-method, where metadata are stored in every device's last sector.
-The kernel module
-.Pa geom_stripe.ko
-will be loaded if it is not loaded already.
-.It Cm stop
-Turn off an existing striped device by its
-.Ar name .
-This command does not touch on-disk metadata!
-.It Cm destroy
-Same as
-.Cm stop .
-.It Cm clear
-Clear metadata on the given devices.
-.It Cm dump
-Dump metadata stored on the given devices.
-.It Cm list
-See
-.Xr geom 8 .
-.It Cm status
-See
-.Xr geom 8 .
-.It Cm load
-See
-.Xr geom 8 .
-.It Cm unload
-See
-.Xr geom 8 .
-.El
-.Pp
-Additional options:
-.Bl -tag -width ".Fl s Ar stripesize"
-.It Fl f
-Force the removal of the specified striped device.
-.It Fl h
-Hardcode providers' names in metadata.
-.It Fl s Ar stripesize
-Specifies size of stripe block in bytes.
-The
-.Ar stripesize
-must be a multiple of the largest sector size of all the providers.
-.It Fl v
-Be more verbose.
-.El
-.Sh SYSCTL VARIABLES
-The following
-.Xr sysctl 8
-variables can be used to control the behavior of the
-.Nm STRIPE
-GEOM class.
-The default value is shown next to each variable.
-.Bl -tag -width indent
-.It Va kern.geom.stripe.debug : No 0
-Debug level of the
-.Nm STRIPE
-GEOM class.
-This can be set to a number between 0 and 3 inclusive.
-If set to 0 minimal debug information is printed, and if set to 3 the
-maximum amount of debug information is printed.
-.It Va kern.geom.stripe.fast : No 0
-If set to a non-zero value enable
-.Dq "fast mode"
-instead of the normal
-.Dq "economic mode" .
-Compared to
-.Dq "economic mode" ,
-.Dq "fast mode"
-uses more memory, but it is much faster for smaller stripe sizes.
-If enough memory cannot be allocated,
-.Nm STRIPE
-will fall back to
-.Dq "economic mode" .
-.It Va kern.geom.stripe.maxmem : No 13107200
-Maximum amount of memory that can be consumed by
-.Dq "fast mode"
-(in bytes).
-This
-.Xr sysctl 8
-variable is read-only and can only be set as a tunable in
-.Xr loader.conf 5 .
-.It Va kern.geom.stripe.fast_failed
-A count of how many times
-.Dq "fast mode"
-has failed due to an insufficient amount of memory.
-If this value is large, you should consider increasing the
-.Va kern.geom.stripe.maxmem
-value.
-.El
-.Sh EXIT STATUS
-Exit status is 0 on success, and 1 if the command fails.
-.Sh EXAMPLES
-The following example shows how to set up a striped device from four disks with a
-128KB stripe size for automatic configuration,
-create a file system on it,
-and mount it:
-.Bd -literal -offset indent
-gstripe label -v -s 131072 data /dev/da0 /dev/da1 /dev/da2 /dev/da3
-newfs /dev/stripe/data
-mount /dev/stripe/data /mnt
-[...]
-umount /mnt
-gstripe stop data
-gstripe unload
-.Ed
-.Sh COMPATIBILITY
-The
-.Nm
-interleave is in number of bytes,
-unlike
-.Xr ccdconfig 8
-which use the number of sectors.
-A
-.Xr ccdconfig 8
-.Ar ileave
-of
-.Ql 128
-is 64 KB (128 512B sectors).
-The same stripe interleave would be specified as
-.Ql 65536
-for
-.Nm .

-.Cm load
-.Nm
-.Cm unload
-.Sh DESCRIPTION
-The
-.Nm
-utility is used for setting up a virtual storage device of arbitrary
-large size
-.Pq for example, several TB ,
-consisting of an arbitrary number of physical storage devices with the
-total size which is equal to or smaller than the virtual size.
-Data for the virtual devices will be allocated from physical devices on
-demand.
-The idea behind
-.Nm
-is similar to the concept of Virtual Memory in operating systems,
-effectively allowing users to overcommit on storage
-.Pq free file system space .
-The concept is also known as "thin provisioning" in virtualization
-environments, only here it is implemented on the level of physical storage
-devices.
-.Pp
-The first argument to
-.Nm
-indicates an action to be performed:
-.Bl -tag -width ".Cm remove"
-.It Cm label
-Set up a virtual device from the given components with the specified
-.Ar name .
-Metadata is stored in the last sector of every component.
-Argument
-.Fl s Ar virsize
-is the size of new virtual device, with default being set to 2 TiB
-.Pq 2097152 MiB .
-Argument
-.Fl m Ar chunksize
-is the chunk size, with default being set to 4 MiB
-.Pq 4096 KiB .
-The default arguments are thus
-.Qq Fl s Ar 2097152 Fl m Ar 4096 .
-.It Cm stop
-Turn off an existing virtual device with the given
-.Ar name .
-This command does not touch on-disk metadata.
-As with other GEOM classes, stopped geoms cannot be started manually.
-.It Cm destroy
-Same as
-.Cm stop.
-.It Cm add
-Adds new components to existing virtual device with the given
-.Ar name .
-The specified virstor device must exist and be active
-.Pq i.e. module loaded, device present in Pa /dev .
-This action can be safely performed while the virstor device is in use
-.Pq Qo hot Qc operation .
-.It Cm remove
-Removes components from existing virtual device with the given
-.Ar name .
-Only unallocated providers can be removed.
-.It Cm clear
-Clear metadata on the given providers.
-.It Cm dump
-Dump metadata stored on the given providers.
-.It Cm list
-See
-.Xr geom 8 .
-.It Cm status
-See
-.Xr geom 8 .
-.It Cm load
-See
-.Xr geom 8 .
-.It Cm unload
-See
-.Xr geom 8 .
-.El
-.Pp
-Additional options:
-.Bl -tag -width ".Fl f"
-.It Fl f
-Force the removal of the specified virtual device.
-.It Fl h
-Hardcode providers' names in metadata.
-.It Fl v
-Be more verbose.
-.El
-.Sh EXAMPLES
-The following example shows how to create a virtual device of default size
-.Pq 2 TiB ,
-of default chunk
-.Pq extent
-size
-.Pq 4 MiB ,
-with two physical devices for backing storage.
-.Bd -literal -offset indent
-.No gvirstor label -v Ar mydata Ar /dev/ada4 Ar /dev/ada6
-.No newfs Ar /dev/virstor/mydata
-.Ed
-.Pp
-From now on, the virtual device will be available via the
-.Pa /dev/virstor/mydata
-device entry.
-To add a new physical device / component to an active virstor device:
-.Bd -literal -offset indent
-.No gvirstor add Ar mydata Ar ada8
-.Ed
-.Pp
-This will add physical storage of
-.Ar ada8
-to
-.Pa /dev/virstor/mydata
-device.
-.Pp
-To see the device status information
-.Pq including how much physical storage is still available for the virtual device ,
-use:
-.Bd -literal -offset indent
-gvirstor list
-.Ed
-.Pp
-All standard
-.Xr geom 8
-subcommands
-.Pq e.g. Cm status , Cm help
-are also supported.
-.Sh SYSCTL VARIABLES
-.Nm
-has several
-.Xr sysctl 8
-tunable variables.
-.Bd -literal -offset indent
-.Va int kern.geom.virstor.debug
-.Ed
-.Pp
-This sysctl controls verbosity of the kernel module, in the range
-1 to 15.
-Messages that are marked with higher verbosity levels than this are
-suppressed.
-Default value is 5 and it is not recommended to set this tunable to less
-than 2, because level 1 messages are error events, and level 2 messages
-are system warnings.
-.Bd -literal -offset indent
-.Va int kern.geom.virstor.chunk_watermark
-.Ed
-.Pp
-Value in this sysctl sets warning watermark level for physical chunk
-usage on a single component.
-The warning is issued when a virstor component has less than this many
-free chunks
-.Pq default 100 .
-.Bd -literal -offset indent
-.Va int kern.geom.virstor.component_watermark
-.Ed
-.Pp
-Value in this sysctl sets warning watermark level for component usage.
-The warning is issued when there are less than this many unallocated
-components
-.Pq default is 1 .
-.Pp
-All these sysctls are also available as
-.Xr loader 8
-tunables.
-.Sh DIAGNOSTICS
-.Ex -std
-.Pp
-.Nm
-kernel module issues log messages with prefixes in standardized format,
-which is useful for log message filtering and dispatching.
-Each message line begins with
-.Bd -literal -offset indent
-.Li GEOM_VIRSTOR[%d]:
-.Ed
-.Pp
-The number
-.Pq %d
-is message verbosity / importance level, in the range 1 to 15.
-If a message filtering, dispatching or operator alert system is used, it
-is recommended that messages with levels 1 and 2 be taken seriously
-.Pq for example, to catch out-of-space conditions as set by watermark
-sysctls.
-.Sh SEE ALSO
-.Xr geom 4 ,
-.Xr fstab 5 ,
-.Xr geom 8 ,
-.Xr glabel 8 ,
-.Xr newfs 8
-.Sh HISTORY
-The
-.Nm
-utility first appeared in
-.Fx 7.0 .
-.Sh AUTHORS
-.An Ivan Voras Aq Mt ivoras@FreeBSD.org
-.Pp
-Sponsored by Google Summer of Code 2006.
-.Sh BUGS
-Commands
-.Cm add
-and
-.Cm remove
-contain unavoidable critical sections which may make the virstor
-device unusable if a power failure
-.Pq or other disruptive event
-happens during their execution.
-It is recommended to run them when the system is quiescent.
-.Sh ASSUMPTIONS AND INTERACTION WITH FILE SYSTEMS
-There are several assumptions that
-.Nm
-has in its operation: that the size of the virtual storage device will not
-change once it is set, and that the sizes of individual physical storage
-components will always remain constant during their existence.
-For alternative ways to implement virtual or resizable file systems see
-.Xr zfs 1M ,
-.Xr gconcat 8
-and
-.Xr growfs 8 .
-.Pp
-Note that
-.Nm
-has nontrivial interaction with file systems which initialize a large
-number of on-disk structures during newfs.
-If such file systems attempt to spread their structures across the drive
-media
-.Pq like UFS/UFS2 does ,
-their efforts will be effectively foiled by sequential allocation of
-chunks in
-.Nm
-and all their structures will be physically allocated at the start
-of the first virstor component.
-This could have a significant impact on file system performance
-.Pq which can in some rare cases be even positive .
