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

NAME         top

       pvdisplay - Display various attributes of physical volume(s)

SYNOPSIS         top

       pvdisplay
           [ option_args ]
           [ position_args ]

DESCRIPTION         top

       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         top

       --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         top

       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         top

       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.
