NAME

       lvdisplay — Display information about a logical volume

SYNOPSIS

       lvdisplay
           [ option_args ]
           [ position_args ]

DESCRIPTION

       lvdisplay shows the attributes of LVs, like size, read/write status, snapshot information, etc.

       lvs(8)  is  a  preferred  alternative  that shows the same information and more, using a more compact and
       configurable output format.

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).

       -c|--colon
              Generate  colon separated output for easier parsing in scripts or programs.  Also see vgs(8) which
              provides considerably more control over the output.

       -C|--columns
              Display output in columns, the equivalent of vgs(8).  Options listed are the same as options given
              in vgs(8).

       --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.

       -m|--maps
              Display  the  mapping  of logical extents to PVs and physical extents.  To map physical extents to
              logical extents use: pvs --segments -o+lv_name,seg_start_pe,segtype

       --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.

       --segments

       -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.

       -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.
