       pvchange - Change attributes of physical volume(s)

SYNOPSIS

       pvchange option_args position_args
           [ option_args ]

DESCRIPTION

       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
           ( -x|--allocatable y|n,
             -u|--uuid,

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).
