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 infor‐
              mation about profiles.

       --config String
              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).

       --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.

       --devices PV
              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 sep‐
              arated list of devices. This overrides the devices file.

       --devicesfile String
              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)  de‐
              vices/devicesfile and devices/use_devicesfile settings.

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

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

       -h|--help
              Display help text.

       --journal String
              Record information in the systemd journal.  This information is in addition to  infor‐
              mation 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.

       --lockopt String
              Used to pass options for special cases to lvmlockd.  See lvmlockd(8) for more informa‐
              tion.

       --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.

       --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.


       --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 re‐
              port/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.  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 selec‐
              table 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-report‐
              ing  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 read‐
              ing 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  ex‐
              tents,  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.)

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).
