OPTIONS         top


       --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)
              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).

       --devices PV
              Devices that the  command  can  use.  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)  command.   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.   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 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
              --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(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         top

       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
              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         top

       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.
