vgmerge — Merge volume groups

Синопсис (Synopsis)

vgmerge position_args [ option_args ]

Описание (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.

Использование (Usage)

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

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

Параметры (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(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.

       -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.

       --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.)

Переменные (Variables)

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.)

Переменные окружения (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.

Примеры (Examples)

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