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.

           [    --profile String ]
           [    --version ]

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
              settings.  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.

       --longhelp
              Display long help text.

       --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: 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         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
