VGDISPLAY(8)   (LVM TOOLS 2.03.11(2) (2021-01-08))   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 compact and configurable
          output format.

     VGDISPLAY(8)   (LVM TOOLS 2.03.11(2) (2021-01-08))   VGDISPLAY(8)

              [    --config String ]
              [    --driverloaded y|n ]
              [    --lockopt String ]

              [    --profile String ]
              [    --version ]

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

          --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 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 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.

     VGDISPLAY(8)   (LVM TOOLS 2.03.11(2) (2021-01-08))   VGDISPLAY(8)

          --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 failures.

          --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.

          --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

     Page 3                    Red Hat, Inc.         (printed 5/25/22)

     VGDISPLAY(8)   (LVM TOOLS 2.03.11(2) (2021-01-08))   VGDISPLAY(8)

               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
               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.

          -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.

          -s|--short
               Give a short listing showing the existence of VGs.

          -O|--sort String

     Page 4                    Red Hat, Inc.         (printed 5/25/22)

     VGDISPLAY(8)   (LVM TOOLS 2.03.11(2) (2021-01-08))   VGDISPLAY(8)

               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 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.

          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

     Page 5                    Red Hat, Inc.         (printed 5/25/22)

     VGDISPLAY(8)   (LVM TOOLS 2.03.11(2) (2021-01-08))   VGDISPLAY(8)

               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.
