pvchange — Change attributes of physical volume(s)

Description

       pvchange changes PV attributes in the VG.

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

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).
       pvchange-xn/dev/sdk1

Name

       pvchange — Change attributes of physical volume(s)

Options

--addtagTag
              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|--allocatabley|n
              Enable or disable allocation of physical extents on this PV.

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

       --commandprofileString
              The  command profile to use for command configuration.  See lvm.conf(5) for more information about
              profiles.

       --configString
              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.

       -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).

       --deltagTag
              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.

       --devicesPV
              Restricts  the  devices  that  are visible and accessible to the command.  Devices not listed will
              appear to be missing. This option can be repeated, or accepts a comma separated list  of  devices.
              This overrides the devices file.

       --devicesfileString
              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)  devices/devicesfile  and
              devices/use_devicesfile settings.

       --driverloadedy|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.

       --journalString
              Record information in the systemd journal.  This information 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.

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

       --longhelp
              Display long help text.

       --metadataignorey|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.

       --nohints
              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.

       --nolocking
              Disable locking. Use with caution, concurrent commands may produce incorrect results.

       --profileString
              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'.

       --reportformatbasic|json|json_std
              Overrides  current output format for reports which is defined 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 identification. json
              produces  report  output  in  JSON format. json_std produces report output in JSON format which is
              more compliant with JSON standard.  See lvmreport(7) for more information.

       -S|--selectString
              Select objects for processing and reporting based on specified criteria.  The criteria  syntax  is
              described  by  --selecthelp  and lvmreport(7).  For reporting commands, one row is displayed for
              each object matching the criteria.  See --optionshelp 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: 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 control --units, where capital letters
              mean multiple of 1000.)
