OPTIONS
       --aligned
              Use with --separator to align the output columns
       -a|--all
              List all VGs. Equivalent to not specifying any VGs.
       --binary
              Use binary values "0" or "1" instead of descriptive literal val-
              ues for columns that have exactly two valid values to report
              (not counting the "unknown" value which denotes that the value
              could not be determined).
       --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 set-
              tings.  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.
       --lockopt String
              Used to pass options for special cases to lvmlockd.  See lvm-
              lockd(8) for more information.
       --logonly
              Suppress command report and display only log report.
       --longhelp
              Display long help text.
       --nameprefixes
              Add an "LVM2_" prefix plus the field name to the output. Useful
              with --noheadings to produce a list of field=value pairs that
              can be used to set environment variables (for example, in udev
              rules).
       --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
              An alias for --commandprofile or --metadataprofile, depending on
              the command.
       -q|--quiet ...
              Suppress output and log messages. Overrides --debug and --ver-
              bose.  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 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 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.
       --rows
              Output columns as rows.
       -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 addi-
              tional "selected" field (-o selected) showing 1 if the row
              matches the selection and 0 otherwise.  For non-reporting com-
              mands 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.
       --trustcache
              Avoids certain device scanning during command processing. Do not
              use.
       --unbuffered
              Produce output immediately without sorting or aligning the col-
              umns 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.
       --unquoted
              When used with --nameprefixes, output values in the field=value
              pairs are not quoted.
       -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 con-
              tent.
       Size[UNIT]
              Size  is  an  input number that accepts an optional unit.  Input
              units are always treated as base two values, regardless of capi-
              talization,  e.g.  'k'  and 'K' both refer to 1024.  The default
              input unit is specified by letter, followed by |UNIT.  UNIT rep-
              resents  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.
NOTES
       The vg_attr bits are:
       1  Permissions: (w)riteable, (r)ead-only
       2  Resi(z)eable
       3  E(x)ported
       4  (p)artial:  one  or  more  physical  volumes belonging to the volume
          group are missing from the system
       5  Allocation policy: (c)ontiguous, c(l)ing, (n)ormal, (a)nywhere
       6  (c)lustered, (s)hared
