OPTIONS         top


       -a|--activate y|n|ay
              Change the active state of LVs.  An active LV can be used
              through a block device, allowing data on the LV to be
              accessed.  y makes LVs active, or available.  n makes LVs
              inactive, or unavailable.  The block device for the LV is
              added or removed from the system using device-mapper in
              the kernel.  A symbolic link /dev/VGName/LVName pointing
              to the device node is also added/removed.  All software
              and scripts should access the device through the symbolic
              link and present this as the name of the device.  The
              location and name of the underlying device node may depend
              on the distribution, configuration (e.g. udev), or release
              version.  ay specifies autoactivation, which is used by
              system-generated activation commands.  By default, LVs are
              autoactivated.  An autoactivation property can be set on a
              VG or LV to disable autoactivation, see
              --setautoactivation y|n in vgchange, lvchange, vgcreate,
              and lvcreate.  Display the property with vgs or lvs "-o
              autoactivation".  The lvm.conf(5)
              auto_activation_volume_list includes names of VGs or LVs
              that should be autoactivated, and anything not listed is
              not autoactivated.  When auto_activation_volume_list is
              undefined (the default), it has no effect.  If
              auto_activation_volume_list is defined and empty, no LVs
              are autoactivated.  Items included by
              auto_activation_volume_list will not be autoactivated if
              the autoactivation property has been disabled.  See
              lvmlockd(8) for more information about activation options
              ey and sy for shared VGs.

       --activationmode partial|degraded|complete
              Determines if LV activation is allowed when PVs are
              missing, e.g. because of a device failure.  complete only
              allows LVs with no missing PVs to be activated, and is the
              most restrictive mode.  degraded allows RAID LVs with
              missing PVs to be activated.  (This does not include the
              "mirror" type, see "raid1" instead.)  partial allows any
              LV with missing PVs to be activated, and should only be
              used for recovery or repair.  For default, see lvm.conf(5)
              activation_mode.  See lvmraid(7) for more information.

       --addtag Tag
              Adds a tag to a PV, VG or LV. This option can be repeated
              to add multiple tags at once. See lvm(8) for information
              about tags.

       --alloc contiguous|cling|cling_by_tags|normal|anywhere|inherit
              Determines the allocation policy when a command needs to
              allocate Physical Extents (PEs) from the VG. Each VG and
              LV has an allocation policy which can be changed with
              vgchange/lvchange, or overridden on the command line.
              normal applies common sense rules such as not placing
              parallel stripes on the same PV.  inherit applies the VG
              policy to an LV.  contiguous requires new PEs be placed
              adjacent to existing PEs.  cling places new PEs on the
              same PV as existing PEs in the same stripe of the LV.  If
              there are sufficient PEs for an allocation, but normal
              does not use them, anywhere will use them even if it
              reduces performance, e.g. by placing two stripes on the
              same PV.  Optional positional PV args on the command line
              can also be used to limit which PVs the command will use
              for allocation.  See lvm(8) for more information about
              allocation.

       -A|--autobackup y|n
              Specifies if metadata should be backed up automatically
              after a change.  Enabling this is strongly advised! See
              vgcfgbackup(8) for more information.

       --cachemode writethrough|writeback|passthrough
              Specifies when writes to a cache LV should be considered
              complete.  writeback considers a write complete as soon as
              it is stored in the cache pool.  writethough considers a
              write complete only when it has been stored in both the
              cache pool and on the origin LV.  While writethrough may
              be slower for writes, it is more resilient if something
              should happen to a device associated with the cache pool
              LV. With passthrough, all reads are served from the origin
              LV (all reads miss the cache) and all writes are forwarded
              to the origin LV; additionally, write hits cause cache
              block invalidates. See lvmcache(7) for more information.

       --cachepolicy String
              Specifies the cache policy for a cache LV.  See
              lvmcache(7) for more information.

       --cachesettings String
              Specifies tunable values for a cache LV in "Key = Value"
              form.  Repeat this option to specify multiple values.
              (The default values should usually be adequate.)  The
              special string value default switches settings back to
              their default kernel values and removes them from the list
              of settings stored in LVM metadata.  See lvmcache(7) for
              more information.

       --commandprofile String
              The command profile to use for command configuration.  See
              lvm.conf(5) for more information about profiles.

       --compression y|n
              Controls whether compression is enabled or disable for VDO
              volume.  See lvmvdo(7) for more information about VDO
              usage.

       --config String
              Config settings for the command. These override
              lvm.conf(5) settings.  The String arg uses the same format
              as lvm.conf(5), or may use section/field syntax.  See
              lvm.conf(5) for more information about config.

       -C|--contiguous y|n
              Sets or resets the contiguous allocation policy for LVs.
              Default is no contiguous allocation based on a next free
              principle.  It is only possible to change a non-contiguous
              allocation policy to contiguous if all of the allocated
              physical extents in the LV are already contiguous.

       -d|--debug ...
              Set debug level. Repeat from 1 to 6 times to increase the
              detail of messages sent to the log file and/or syslog (if
              configured).

       --deduplication y|n
              Controls whether deduplication is enabled or disable for
              VDO volume.  See lvmvdo(7) for more information about VDO
              usage.

       --deltag Tag
              Deletes a tag from a PV, VG or LV. This option can be
              repeated to delete multiple tags at once. See lvm(8) for
              information about tags.

       --detachprofile
              Detaches a metadata profile from a VG or LV.  See
              lvm.conf(5) for more information about profiles.

       --devices PV
              Devices that the command can use. This option can be
              repeated or accepts a comma separated list of devices.
              This overrides the devices file.

       --devicesfile String
              A file listing devices that LVM should use.  The file must
              exist in /etc/lvm/devices/ and is managed with the
              lvmdevices(8) command.  This overrides the lvm.conf(5)
              devices/devicesfile and devices/use_devicesfile settings.

       --discards passdown|nopassdown|ignore
              Specifies how the device-mapper thin pool layer in the
              kernel should handle discards.  ignore causes the thin
              pool to ignore discards.  nopassdown causes the thin pool
              to process discards itself to allow reuse of unneeded
              extents in the thin pool.  passdown causes the thin pool
              to process discards itself (like nopassdown) and pass the
              discards to the underlying device.  See lvmthin(7) for
              more information.

       --driverloaded y|n
              If set to no, the command will not attempt to use device-
              mapper.  For testing and debugging.

       --errorwhenfull y|n
              Specifies thin pool behavior when data space is exhausted.
              When yes, device-mapper will immediately return an error
              when a thin pool is full and an I/O request requires
              space.  When no, device-mapper will queue these I/O
              requests for a period of time to allow the thin pool to be
              extended.  Errors are returned if no space is available
              after the timeout.  (Also see dm-thin-pool kernel module
              option no_space_timeout.)  See lvmthin(7) for more
              information.

       -f|--force ...
              Override various checks, confirmations and protections.
              Use with extreme caution.

       -h|--help
              Display help text.

       -K|--ignoreactivationskip
              Ignore the "activation skip" LV flag during activation to
              allow LVs with the flag set to be activated.

       --ignorelockingfailure
              Allows a command to continue with read-only metadata
              operations after locking failures.

       --ignoremonitoring
              Do not interact with dmeventd unless --monitor is
              specified.  Do not use this if dmeventd is already
              monitoring a device.

       --journal String
              Record information in the systemd journal.  This
              information is in addition to information enabled by the
              lvm.conf log/journal setting.  command: record information
              about the command.  output: record the default command
              output.  debug: record full command debugging.

       --lockopt String
              Used to pass options for special cases to lvmlockd.  See
              lvmlockd(8) for more information.

       --longhelp
              Display long help text.

       -j|--major Number
              Sets the major number of an LV block device.

       --[raid]maxrecoveryrate Size[k|UNIT]
              Sets the maximum recovery rate for a RAID LV.  The rate
              value is an amount of data per second for each device in
              the array.  Setting the rate to 0 means it will be
              unbounded.  See lvmraid(7) for more information.

       --metadataprofile String
              The metadata profile to use for command configuration.
              See lvm.conf(5) for more information about profiles.

       --minor Number
              Sets the minor number of an LV block device.

       --[raid]minrecoveryrate Size[k|UNIT]
              Sets the minimum recovery rate for a RAID LV.  The rate
              value is an amount of data per second for each device in
              the array.  Setting the rate to 0 means it will be
              unbounded.  See lvmraid(7) for more information.

       --monitor y|n
              Start (yes) or stop (no) monitoring an LV with dmeventd.
              dmeventd monitors kernel events for an LV, and performs
              automated maintenance for the LV in reponse to specific
              events.  See dmeventd(8) for more information.

       --nohints
              Do not use the hints file to locate devices for PVs. A
              command may read more devices to find PVs when hints are
              not used. The command will still perform standard hint
              file invalidation where appropriate.

       --nolocking
              Disable locking.

       --noudevsync
              Disables udev synchronisation. The process will not wait
              for notification from udev. It will continue irrespective
              of any possible udev processing in the background. Only
              use this if udev is not running or has rules that ignore
              the devices LVM creates.

       -P|--partial
              Commands will do their best to activate LVs with missing
              PV extents.  Missing extents may be replaced with error or
              zero segments according to the  missing_stripe_filler
              setting.  Metadata may not be changed with this option.

       -p|--permission rw|r
              Set access permission to read only r or read and write rw.

       -M|--persistent y|n
              When yes, makes the specified minor number persistent.

       --poll y|n
              When yes, start the background transformation of an LV.
              An incomplete transformation, e.g. pvmove or lvconvert
              interrupted by reboot or crash, can be restarted from the
              last checkpoint with --poll y.  When no, background
              transformation of an LV will not occur, and the
              transformation will not complete. It may not be
              appropriate to immediately poll an LV after activation, in
              which case --poll n can be used to defer polling until a
              later --poll y command.

       --profile String
              An alias for --commandprofile or --metadataprofile,
              depending on the command.

       -q|--quiet ...
              Suppress output and log messages. Overrides --debug and
              --verbose.  Repeat once to also suppress any prompts with
              answer 'no'.

       -r|--readahead auto|none|Number
              Sets read ahead sector count of an LV.  auto is the
              default which allows the kernel to choose a suitable value
              automatically.  none is equivalent to zero.

       --readonly
              Run the command in a special read-only mode which will
              read on-disk metadata without needing to take any locks.
              This can be used to peek inside metadata used by a virtual
              machine image while the virtual machine is running. No
              attempt will be made to communicate with the device-mapper
              kernel driver, so this option is unable to report whether
              or not LVs are actually in use.

       --rebuild PV
              Selects a PV to rebuild in a raid LV. Multiple PVs can be
              rebuilt by repeating this option.  Use this option in
              place of --resync or --syncaction repair when the PVs with
              corrupted data are known, and their data should be
              reconstructed rather than reconstructing default
              (rotating) data.  See lvmraid(7) for more information.

       --refresh
              If the LV is active, reload its metadata.  This is not
              necessary in normal operation, but may be useful if
              something has gone wrong, or if some form of manual LV
              sharing is being used.

       --reportformat basic|json
              Overrides current output format for reports which is
              defined globally by the report/output_format setting in
              lvm.conf(5).  basic is the original format with columns
              and rows.  If there is more than one report per command,
              each report is prefixed with the report name for
              identification. json produces report output in JSON
              format. See lvmreport(7) for more information.

       --resync
              Initiates mirror synchronization. Synchronization
              generally happens automatically, but this option forces it
              to run.  Also see --rebuild to synchronize a specific PV.
              During synchronization, data is read from the primary
              mirror device and copied to the others. This can take
              considerable time, during which the LV is without a
              complete redundant copy of the data.  See lvmraid(7) for
              more information.

       -S|--select String
              Select objects for processing and reporting based on
              specified criteria.  The criteria syntax is described by
              --select help and lvmreport(7).  For reporting commands,
              one row is displayed for each object matching the
              criteria.  See --options help for selectable object
              fields.  Rows can be displayed with an additional
              "selected" field (-o selected) showing 1 if the row
              matches the selection and 0 otherwise.  For non-reporting
              commands which process LVM entities, the selection is used
              to choose items to process.

       -k|--setactivationskip y|n
              Persistently sets (yes) or clears (no) the "activation
              skip" flag on an LV.  An LV with this flag set is not
              activated unless the --ignoreactivationskip option is used
              by the activation command.  This flag is set by default on
              new thin snapshot LVs.  The flag is not applied to
              deactivation.  The current value of the flag is indicated
              in the lvs lv_attr bits.

       --setautoactivation y|n
              Set the autoactivation property on a VG or LV.  Display
              the property with vgs or lvs "-o autoactivation".  When
              the autoactivation property is disabled, the VG or LV will
              not be activated by a command doing autoactivation
              (vgchange, lvchange, or pvscan using -aay.)  If
              autoactivation is disabled on a VG, no LVs will be
              autoactivated in that VG, and the LV autoactivation
              property has no effect.  If autoactivation is enabled on a
              VG, autoactivation can be disabled for individual LVs.

       --[raid]syncaction check|repair
              Initiate different types of RAID synchronization.  This
              causes the RAID LV to read all data and parity blocks in
              the array and check for discrepancies (mismatches between
              mirrors or incorrect parity values).  check will count but
              not correct discrepancies.  repair will correct
              discrepancies.  See lvs(8) for reporting discrepancies
              found or repaired.

       --sysinit
              Indicates that vgchange/lvchange is being invoked from
              early system initialisation scripts (e.g. rc.sysinit or an
              initrd), before writable filesystems are available. As
              such, some functionality needs to be disabled and this
              option acts as a shortcut which selects an appropriate set
              of options. Currently, this is equivalent to using
              --ignorelockingfailure, --ignoremonitoring, --poll n, and
              setting env var LVM_SUPPRESS_LOCKING_FAILURE_MESSAGES.
              vgchange/lvchange skip autoactivation, and defer to pvscan
              autoactivation.

       -t|--test
              Run in test mode. Commands will not update metadata.  This
              is implemented by disabling all metadata writing but
              nevertheless returning success to the calling function.
              This may lead to unusual error messages in multi-stage
              operations if a tool relies on reading back metadata it
              believes has changed but hasn't.

       -v|--verbose ...
              Set verbose level. Repeat from 1 to 4 times to increase
              the detail of messages sent to stdout and stderr.

       --version
              Display version information.

       --[raid]writebehind Number
              The maximum number of outstanding writes that are allowed
              to devices in a RAID1 LV that is marked write-mostly.
              Once this value is exceeded, writes become synchronous
              (i.e. all writes to the constituent devices must complete
              before the array signals the write has completed). Setting
              the value to zero clears the preference and allows the
              system to choose the value arbitrarily.

       --[raid]writemostly PV[:t|n|y]
              Mark a device in a RAID1 LV as write-mostly.  All reads to
              these drives will be avoided unless absolutely necessary.
              This keeps the number of I/Os to the drive to a minimum.
              The default behavior is to set the write-mostly attribute
              for the specified PV.  It is also possible to remove the
              write-mostly flag by adding the suffix :n at the end of
              the PV name, or to toggle the value with the suffix :t.
              Repeat this option to change the attribute on multiple
              PVs.

       -y|--yes
              Do not prompt for confirmation interactively but always
              assume the answer yes. Use with extreme caution.  (For
              automatic no, see -qq.)

       -Z|--zero y|n
              Set zeroing mode for thin pool. Note: already provisioned
              blocks from pool in non-zero mode are not cleared in
              unwritten parts when setting --zero y.

VARIABLES         top

       VG     Volume Group name.  See lvm(8) for valid names.

       LV     Logical Volume name.  See lvm(8) for valid names.  An LV
              positional arg generally includes the VG name and LV name,
              e.g. VG/LV.  LV1 indicates the LV must have a specific
              type, where the accepted LV types are listed. (raid
              represents raid<N> type).

       Tag    Tag name.  See lvm(8) for information about tag names and
              using tags in place of a VG, LV or PV.

       Select Select indicates that a required positional parameter can
              be omitted if the --select option is used.  No arg appears
              in this position.

       String See the option description for information about the
              string content.

       Size[UNIT]
              Size is an input number that accepts an optional unit.
              Input units are always treated as base two values,
              regardless of capitalization, e.g. 'k' and 'K' both refer
              to 1024.  The default input unit is specified by letter,
              followed by |UNIT.  UNIT represents other possible input
              units: b|B is bytes, s|S is sectors of 512 bytes, k|K is
              KiB, m|M is MiB, g|G is GiB, t|T is TiB, p|P is PiB, e|E
              is EiB.  (This should not be confused with the output
              control --units, where capital letters mean multiple of
              1000.)

ENVIRONMENT VARIABLES         top

       See lvm(8) for information about environment variables used by
       lvm.  For example, LVM_VG_NAME can generally be substituted for a
       required VG parameter.
