              Use with --separator to align the output columns

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

              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

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

              Display help text.

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

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

       --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

              Suppress command report and display only log report.

              Display long help text.

              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).

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

              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.

              Disable  locking.  Use  with  caution,  concurrent  commands  may produce incorrect

              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'.

              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
              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.

              Output columns as rows.

              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.

              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.

              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.

              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.

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

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

              Display version information.

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


       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  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.)


       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.


       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
          (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

          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.
