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 settings.  The String arg
              uses the same format as lvm.conf, 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).

       --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 metadata/record_lvs_history was enabled.

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

       --ignoreskippedcluster
              Use to avoid exiting with an non-zero status code if the command is run without
              clustered locking and clustered VGs are skipped.

       --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.

       --nolocking
              Disable locking.

       --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 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.  It can also be used
              to peek inside the metadata of clustered VGs when clustered locking is not
              configured or 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
              Overrides current output format for reports which is defined globally by the
              report/output_format setting in lvm.conf.  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.

       --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.

       --trustcache
              Avoids certain device scanning during command processing. Do not use.

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

       --units 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: bBsSkKmMgGtTpPeE.  b|B is bytes, s|S is
              sectors  of 512 bytes, k|K is kilobytes, m|M is megabytes, g|G is gigabytes, t|T is
              terabytes, p|P is petabytes, e|E is exabytes.  (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, 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.
          (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.

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