OPTIONS

       -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  kernel options for dm-cache or dm-writecache LVs.  Use the form
              'option=value' or 'option1=value option2=value', or repeat --cachesettings for each
              option  being  set.  These settings override the default kernel behaviors which are
              usually adequate.  To  remove  cachesettings  and  revert  to  the  default  kernel
              behaviors,   use   --cachesettings  'default'  for  dm-cache  or  an  empty  string
              --cachesettings '' for dm-writecache.  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
              Restricts  the devices that are visible and accessible to the command.  Devices not
              listed will appear to be missing. 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. Use  with  caution,  concurrent  commands  may  produce  incorrect
              results.

       --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.

       --vdosettings String
              Specifies  tunable  VDO  options  for  VDO  LVs.   Use  the  form 'option=value' or
              'option1=value option2=value', or repeat --vdosettings for each option  being  set.
              These  settings  override  the  default  VDO  behaviors.  To remove vdosettings and
              revert to the default VDO behaviors, use --vdosettings  'default'.   See  lvmvdo(7)
              for more information.

       -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

       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

       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.

EXAMPLES

       Change LV permission to read-only:
       lvchange -pr vg00/lvol1
