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

NAME
       vgmerge - Merge volume groups

SYNOPSIS
       vgmerge position_args
           [ option_args ]

DESCRIPTION
       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.

USAGE
       vgmerge VG VG
           [ -A|--autobackup y|n ]
           [ -l|--list ]
           [ COMMON_OPTIONS ]

       Common options for lvm:
           [ -d|--debug ]
           [ -h|--help ]
           [ -q|--quiet ]
           [ -t|--test ]
           [ -v|--verbose ]
           [ -y|--yes ]
           [    --commandprofile String ]
           [    --config String ]
           [    --driverloaded y|n ]
           [    --lockopt String ]
           [    --longhelp ]
           [    --nolocking ]
           [    --profile String ]
           [    --version ]

OPTIONS
       -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 set-
              tings.  The String arg uses the same format as lvm.conf, 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).

       --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.

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

       --lockopt String
              Used to pass options for special cases to lvmlockd.  See lvm-
              lockd(8) for more information.

       --longhelp
              Display long help text.

       --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'.

       -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 un-
              usual 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 de-
              tail 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.

       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: bBsSkKmMgGtTpPeE.  b|B is
              bytes, s|S is sectors of 512 bytes, k|K  is  kilobytes,  m|M  is
              megabytes, g|G is gigabytes, t|T is terabytes, p|P is petabytes,
              e|E is exabytes.  (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
       Merge  an inactive VG named "vg00" into the active or inactive VG named
       "databases", giving verbose runtime information.
       vgmerge -v databases vg00
