VGDISPLAY(8)                           System Manager's Manual                          VGDISPLAY(8)



NAME
       vgdisplay - Display volume group information

SYNOPSIS
       vgdisplay
           [ option_args ]
           [ position_args ]

DESCRIPTION
       vgdisplay shows the attributes of VGs, and the associated PVs and LVs.

       vgs(8) is a preferred alternative that shows the same information and more, using a more com‐
       pact and configurable output format.

OPTIONS
       -A|--activevolumegroups
              Only select active VGs. The VG is considered active if at least one of its LVs is ac‐
              tive.

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

       --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 de‐
              notes 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 infor‐
              mation 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 de‐
              bugging.

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

       -h|--help
              Display help text.

       --ignorelockingfailure
              Allows a command to continue with read-only metadata operations after locking fail‐
              ures.

       --lockopt String
              Used to pass options for special cases to lvmlockd.  See lvmlockd(8) for more informa‐
              tion.

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

       --longhelp
              Display long help text.

       --noheadings
              Suppress the headings line that is normally the first line of output.  Useful if grep‐
              ping 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 de‐
              fault 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 com‐
              pact 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 report‐
              ing.

       --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 commu‐
              nicate 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 re‐
              port/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 lvmre‐‐
              port(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 se‐
              lectable 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-report‐
              ing 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.

       -s|--short
              Give a short listing showing the existence of 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 read‐
              ing back metadata it believes has changed but hasn't.

       --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)er‐
              abytes, (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.

       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 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.
