OPTIONS         top

              Use with --separator to align the output columns

              Show information about devices that have not been initial‐
              ized by LVM, i.e. they are not PVs.

              Use binary values "0" or "1" instead of descriptive liter‐
              al  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).

       --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(5) settings.  The String arg uses the same format
              as lvm.conf(5), 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

       --devices PV
              Devices  that  the command can use. This option can be re‐
              peated or accepts a comma separated list of devices.  This
              overrides the devices file.

       --devicesfile String
              A file listing devices that LVM should use.  The file must
              exist   in  /etc/lvm/devices/  and  is  managed  with  the
              lvmdevices(8) command.  This overrides the lvm.conf(5) de‐
              vices/devicesfile and devices/use_devicesfile settings.

       --driverloaded y|n
              If set to no, the command will not attempt to use  device-
              mapper.  For testing and debugging.

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

              Display help text.

              Allows a command to continue with read-only metadata oper‐
              ations after locking failures.

       --journal String
              Record  information in the systemd journal.  This informa‐
              tion is in addition to information enabled by the lvm.conf
              log/journal setting.  command:  record  information  about
              the  command.   output: record the default command output.
              debug: record full command debugging.

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

              Suppress command report and display only log report.

              Display long help text.

              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).

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

              Do not use the hints file to locate  devices  for  PVs.  A
              command  may  read more devices to find PVs when hints are
              not used. The command will  still  perform  standard  hint
              file invalidation where appropriate.

              Disable locking.

              Suppress the suffix on output sizes. Use with --units (ex‐
              cept 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  (re‐
              moving 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  op‐
              tion:  -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(5) report section for more con‐
              fig  options.  See lvmreport(7) for more information about

       --profile String
              An alias for --commandprofile  or  --metadataprofile,  de‐
              pending on the command.

       -q|--quiet ...
              Suppress  output  and  log messages. Overrides --debug and
              --verbose.  Repeat once to also suppress any prompts  with
              answer 'no'.

              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 at‐
              tempt  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 de‐
              fined globally  by  the  report/output_format  setting  in
              lvm.conf(5).   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 identifi‐
              cation.  json  produces  report output in JSON format. See
              lvmreport(7) for more information.

              Output columns as rows.

              Produces one line of output for each contiguous allocation
              of space on each PV, showing the start  (pvseg_start)  and
              length (pvseg_size) in units of physical extents.

       -S|--select String
              Select objects for processing and reporting based on spec‐
              ified criteria.  The criteria syntax is described by --se‐
              lect  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 se‐
              lected) 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

       --separator String
              String  to use to separate each column. Useful if grepping
              the output.

              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.  Re‐
              places  the  default  selection. Precede any column with -
              for a reverse sort on that column.

              Run in test mode. Commands will not update metadata.  This
              is implemented by disabling all metadata writing but  nev‐
              ertheless  returning success to the calling function. This
              may lead to unusual error messages in  multi-stage  opera‐
              tions  if  a  tool  relies on reading back metadata it be‐
              lieves has changed but hasn't.

              Produce output immediately without sorting or aligning the
              columns properly.

       --units [Number]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)ec‐
              tors,  (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 speci‐
              fied, e.g. --units 3M.

              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.

              Display version information.

              Do not prompt for confirmation  interactively  but  always
              assume the answer yes. Use with extreme caution.  (For au‐
              tomatic no, see -qq.)

VARIABLES         top

       PV     Physical Volume name, a device path under /dev.  For com‐
              mands managing physical extents, a PV positional arg gen‐
              erally 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 is an input number that accepts an optional unit.
              Input units are always treated as base two values, regard‐
              less of capitalization, e.g. 'k' and 'K' both refer to
              1024.  The default input unit is specified by letter, fol‐
              lowed by |UNIT.  UNIT represents other possible input
              units: 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 con‐
              trol --units, where capital letters mean multiple of


       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.
