       pvchange changes PV attributes in the VG.

       For options listed in parentheses, any one is required, after which the others are optional.

USAGE

       Change properties of all PVs.

       pvchange

OPTIONS

       --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

       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

       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

       Disallow the allocation of physical extents on a PV (e.g. because of disk errors, or because it  will  be
       removed after freeing it).
