VGMERGE(8)               System Manager's Manual              VGMERGE(8)

NAME         top

       vgmerge — Merge volume groups

SYNOPSIS         top

       vgmerge position_args
           [ option_args ]

DESCRIPTION         top

       vgmerge merges two existing VGs. The inactive source VG is merged
       into the destination VG if physical extent sizes are equal and PV
       and LV summaries of both VGs fit into the destination VG's
       limits.

OPTIONS         top


       -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 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.

       -l|--list
              Display merged destination VG like vgdisplay -v.

       --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.

       --poolmetadataspare y|n
              Enable or disable the automatic creation and management of
              a spare pool metadata LV in the VG. A spare metadata LV is
              reserved space that can be used when repairing a pool.

       --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'.

       -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         top

       VG     Volume Group name.  See lvm(8) for valid names.

       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.

EXAMPLES         top

       Merge an inactive VG named "vg00" into the active or inactive VG
       named "databases", giving verbose runtime information.
       vgmerge -v databases vg00
