OPTIONS
       --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(5) set-
              tings.   The  String arg uses the same format as lvm.conf(5), or
              may use section/field syntax.  See lvm.conf(5) for more informa-
              tion 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).
       --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  separated  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)  com-
              mand.   This  overrides  the lvm.conf(5) devices/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 debugging.
       -h|--help
              Display help text.
       --journal String
              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.  out-
              put: record the default command output.  debug: record full com-
              mand debugging.
       --lockopt String
              Used  to  pass  options for special cases to lvmlockd.  See lvm-
              lockd(8) for more information.
       --longhelp
              Display long help text.
       --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.
       --profile String
              An alias for --commandprofile or --metadataprofile, depending on
              the command.
       -q|--quiet ...
              Suppress output and log messages. Overrides --debug  and  --ver-
              bose.   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(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.
       -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.
       --updatemetadata
              Update VG metadata to correct  problems.   If  VG  metadata  was
              updated while a PV was missing, and the PV reappears with an old
              version of metadata, then this option (or any other command that
              writes  metadata)  will  update  the  metadata on the previously
              missing PV. If a PV was removed from a VG while it was  missing,
              and  the PV reappears, using this option will clear the outdated
              metadata from the previously missing PV.  If  metadata  text  is
              damaged  on  one  PV, using this option will replace the damaged
              metadata text. For more severe damage, e.g.  with  headers,  see
              pvck(8).
       -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
       VG     Volume Group name.  See lvm(8) for valid names.
       Tag    Tag name.  See lvm(8) for information about tag names and  using
              tags in place of a VG, LV or PV.
       String See the option description for information about the string con-
              tent.
       Size[UNIT]
              Size is an input number that accepts an  optional  unit.   Input
              units are always treated as base two values, regardless of capi-
              talization, e.g. 'k' and 'K' both refer to  1024.   The  default
              input unit is specified by letter, followed by |UNIT.  UNIT rep-
              resents 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.
