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.
       --ignorelockingfailure
              Allows  a command to continue with read-only metadata operations
              after locking failures.
       --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.
       --mknodes
              Also  checks  the  LVM special files in /dev that are needed for
              active LVs and creates any missing ones and removes unused ones.
       --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.
       --notifydbus
              Send  a  notification  to  D-Bus.  The command will exit with an
              error if LVM is not built with support for  D-Bus  notification,
              or if the notify_dbus config setting is disabled.
       --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.
       -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
       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.
