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 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.

       --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.

       --segments
	      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 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
       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 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 pv_attr bits are:

       1  (d)uplicate, (a)llocatable, (u)sed

       2  e(x)ported

       3  (m)issing
