OPTIONS         top

       --addtag Tag
              Adds a tag to a PV, VG or LV. This option can be repeated to
              add multiple tags at once. See lvm(8) for information about
              tags.

       -a|--all
              Change all visible PVs.

       -x|--allocatable y|n
              Enable or disable allocation of physical extents on this PV.

       -A|--autobackup y|n
              Specifies if metadata should be backed up automatically after
              a change.  Enabling this is strongly advised! See
              vgcfgbackup(8) for more information.

       --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.

       -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).

       --deltag Tag
              Deletes a tag from a PV, VG or LV. This option can be repeated
              to delete multiple tags at once. See lvm(8) for information
              about tags.

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

       -f|--force ...
              Override various checks, confirmations and protections.  Use
              with extreme caution.

       -h|--help
              Display help text.

       --ignoreskippedcluster
              Use to avoid exiting with an non-zero status code if the
              command is run without clustered locking and clustered VGs are
              skipped.

       --longhelp
              Display long help text.

       --metadataignore y|n
              Specifies the metadataignore property of a PV.  If yes,
              metadata areas on the PV are ignored, and lvm will not store
              metadata in the metadata areas of the PV.  If no, lvm will
              store metadata on the PV.

       --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'.

       --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.

       -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.

       -u|--uuid
              Generate new random UUID for specified PVs.

       -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]...

       Select
              Select indicates that a required positional parameter can be
              omitted if the --select option is used.  No arg appears in
              this position.

       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.

EXAMPLES         top

       Disallow the allocation of physical extents on a PV (e.g. because of
       disk errors, or because it will be removed after freeing it).
       pvchange -x n /dev/sdk1
