OPTIONS

       --aligned
              Use with --separator to align the output columns

       -a|--all
              Show  information  about internal LVs.  These are components of normal LVs, such as
              mirrors, which are not independently accessible, e.g. not mountable.

       --binary
              Use binary values "0" or "1" instead of descriptive literal values for columns that
              have  exactly  two  valid  values to report (not counting the "unknown" value which
              denotes that the value could not be determined).

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

       --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.

       --configreport log|vg|lv|pv|pvseg|seg
              See lvmreport(7).

       -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).

       --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.

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

       --foreign
              Report/display foreign VGs that would otherwise be skipped.  See lvmsystemid(7) for
              more information about foreign VGs.

       -h|--help
              Display help text.

       -H|--history
              Include historical LVs in the output.  (This has no effect unless LVs were  removed
              while lvm.conf(5) metadata/record_lvs_history was enabled.

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

       --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.

       --logonly
              Suppress command report and display only log report.

       --longhelp
              Display long help text.

       --nameprefixes
              Add an "LVM2_" prefix plus the field name to the output. Useful  with  --noheadings
              to  produce  a  list  of  field=value  pairs  that  can  be used to set environment
              variables (for example, in udev rules).

       --noheadings
              Suppress the headings line that is normally the first line of  output.   Useful  if
              grepping the output.

       --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.

       --nosuffix
              Suppress the suffix on  output  sizes.  Use  with  --units  (except  h  and  H)  if
              processing the output.

       -o|--options String
              Comma-separated,  ordered  list of fields to display in columns.  String arg syntax
              is: [+|-|#]Field1[,Field2 ...]  The prefix + will append the  specified  fields  to
              the default fields, - will remove the specified fields from the default fields, and
              # will compact specified fields (removing them when empty for all  rows.)   Use  -o
              help  to  view  the  list of all available fields.  Use separate lists of fields to
              add,  remove  or   compact   by   repeating   the   -o   option:   -o+field1,field2
              -o-field3,field4  -o#field5.   These  lists  are evaluated from left to right.  Use
              field name lv_all to view all LV fields,  vg_all  all  VG  fields,  pv_all  all  PV
              fields,  pvseg_all  all  PV  segment  fields,  seg_all  all  LV segment fields, and
              pvseg_all all PV segment columns.  See the  lvm.conf(5)  report  section  for  more
              config options.  See lvmreport(7) for more information about reporting.

       --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'.

       --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.

       --reportformat basic|json|json_std
              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. json_std produces report output in JSON format which is more compliant
              with JSON standard.  See lvmreport(7) for more information.

       --rows
              Output columns as rows.

       --segments
              Use default columns that emphasize segment 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.

       --separator String
              String to use to separate each column. Useful if grepping the output.

       --shared
              Report/display  shared  VGs  that  would  otherwise be skipped when lvmlockd is not
              being used on the host.  See lvmlockd(8) for more information about shared VGs.

       -O|--sort String
              Comma-separated ordered list of columns to sort by. Replaces the default selection.
              Precede any column with - for a reverse sort on that column.

       -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.

       --unbuffered
              Produce output immediately without sorting or aligning the columns properly.

       --units [Number]r|R|h|H|b|B|s|S|k|K|m|M|g|G|t|T|p|P|e|E
              All sizes are output in these units: human-(r)eadable with '<' rounding  indicator,
              (h)uman-readable,   (b)ytes,   (s)ectors,  (k)ilobytes,  (m)egabytes,  (g)igabytes,
              (t)erabytes, (p)etabytes, (e)xabytes.  Capitalise to use multiples of  1000  (S.I.)
              instead of 1024.  Custom units can be specified, e.g. --units 3M.

       --unquoted
              When  used  with  --nameprefixes,  output  values  in the field=value pairs are not
              quoted.

       -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.

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

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.

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

       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.

NOTES

       The lv_attr bits are:

       1  Volume  type:  (C)ache, (m)irrored, (M)irrored without initial sync, (o)rigin, (O)rigin
          with merging  snapshot,  (r)aid,  (R)aid  without  initial  sync,  (s)napshot,  merging
          (S)napshot,  (p)vmove,  (v)irtual,  mirror or raid (i)mage, mirror or raid (I)mage out-
          of-sync, mirror (l)og device, under (c)onversion, thin (V)olume,  (t)hin  pool,  (T)hin
          pool data, v(d)o pool, v(D)o pool data, raid or pool m(e)tadata or pool metadata spare.

       2  Permissions: (w)riteable, (r)ead-only, (R)ead-only activation of non-read-only volume

       3  Allocation  policy:   (a)nywhere,  (c)ontiguous, (i)nherited, c(l)ing, (n)ormal This is
          capitalised if the volume is currently locked against allocation changes,  for  example
          during pvmove(8).

       4  fixed (m)inor

       5  State:  (a)ctive,  (h)istorical,  (s)uspended,  (I)nvalid snapshot, invalid (S)uspended
          snapshot, snapshot (m)erge failed, suspended snapshot (M)erge failed,  mapped  (d)evice
          present  without tables, mapped device present with (i)nactive table, thin-pool (c)heck
          needed, suspended thin-pool (C)heck needed, (X) unknown

       6  device (o)pen, (X) unknown

       7  Target type: (C)ache, (m)irror, (r)aid, (s)napshot, (t)hin, (u)nknown, (v)irtual.  This
          groups  logical  volumes  related to the same kernel target together.  So, for example,
          mirror images, mirror logs as well as mirrors themselves appear as (m) if they use  the
          original  device-mapper mirror kernel driver; whereas the raid equivalents using the md
          raid kernel driver all appear as  (r).   Snapshots  using  the  original  device-mapper
          driver appear as (s); whereas snapshots of thin volumes using the new thin provisioning
          driver appear as (t).

       8  Newly-allocated data blocks are overwritten with blocks of (z)eroes before use.

       9  Volume Health, where there are currently three groups of attributes identified:

          Common ones for all Logical Volumes: (p)artial, (X) unknown.
          (p)artial signifies that one or more of the Physical Volumes this Logical  Volume  uses
          is missing from the system. (X) unknown signifies the status is unknown.

          Related to RAID Logical Volumes: (r)efresh needed, (m)ismatches exist, (w)ritemostly.
          (r)efresh  signifies  that one or more of the Physical Volumes this RAID Logical Volume
          uses had suffered a write error. The write error could be due to a temporary failure of
          that  Physical  Volume  or  an  indication  that  it  is failing.  The device should be
          refreshed or replaced. (m)ismatches signifies that the RAID logical volume has portions
          of  the  array  that  are  not  coherent.  Inconsistencies are detected by initiating a
          "check" on a RAID logical volume.  (The scrubbing operations, "check" and "repair", can
          be  performed  on  a  RAID  logical  volume via the 'lvchange' command.)  (w)ritemostly
          signifies the devices in a RAID 1 logical volume that have  been  marked  write-mostly.
          Re(s)haping   signifies   a   RAID   Logical  Volume  is  either  undergoing  a  stripe
          addition/removal, a stripe size or  RAID  algorithm  change.   (R)emove  after  reshape
          signifies freed striped raid images to be removed.

          Related  to  Thin  pool Logical Volumes: (F)ailed, out of (D)ata space, (M)etadata read
          only.
          (F)ailed is set if thin pool encounters serious failures and hence no  further  I/O  is
          permitted  at  all.  The  out  of  (D)ata space is set if thin pool has run out of data
          space. (M)etadata read only signifies  that  thin  pool  encounters  certain  types  of
          failures  but  it's  still  possible  to do reads at least, but no metadata changes are
          allowed.

          Related to Thin Logical Volumes: (F)ailed.
          (F)ailed is set when related thin pool enters  Failed  state  and  no  further  I/O  is
          permitted at all.

          Related to writecache logical volumes: (E)rror.
          (E)rror is set dm-writecache reports an error.

       10 s(k)ip activation: this volume is flagged to be skipped during activation.
