NAME

       pvdisplay - Display various attributes of physical volume(s)

SYNOPSIS

       pvdisplay
           [ option_args ]
           [ position_args ]

DESCRIPTION

       pvdisplay  shows the attributes of PVs, like size, physical extent size, space used for the VG descriptor
       area, etc.

       pvs(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 devices that have not been initialized by LVM, i.e. they are not PVs.

       --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.

       --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.

       --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.

       -m|--maps
              Display the mapping of physical extents to LVs and logical extents.

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

       --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.

       -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
              Only display the size of the given PVs.

       -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 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

       PV
              Physical  Volume  name,  a  device  path under /dev.  For commands managing physical extents, a PV
              positional arg generally accepts a suffix indicating a range  (or  multiple  ranges)  of  physical
              extents  (PEs). When the first PE is omitted, it defaults to the start of the device, and when the
              last PE is omitted it defaults to end.  Start and end range (inclusive): PV[:PE-PE]...  Start  and
              length range (counting from 0): PV[:PE+PE]...

       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.
