NAME         top

       vgimportclone — Import a VG from cloned PVs

SYNOPSIS         top

       vgimportclone position_args
           [ option_args ]

DESCRIPTION         top

       vgimportclone imports a VG from duplicated PVs, e.g. created by a
       hardware snapshot of existing PVs.

       A duplicated VG cannot used until it is made to coexist with the
       original VG. vgimportclone renames the VG associated with the
       specified PVs and changes the associated VG and PV UUIDs.

OPTIONS         top


       -n|--basevgname String
              By default the snapshot VG will be renamed to the original
              name plus a numeric suffix to avoid duplicate naming (e.g.
              'test_vg' would be renamed to 'test_vg1'). This option
              will override the base VG name that is used for all VG
              renames. If a VG already exists with the specified name a
              numeric suffix will be added (like the previous example)
              to make it unique.

       --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.

       -i|--import
              Import exported VGs. Otherwise VGs that have been exported
              will not be changed (nor will their associated PVs).

       --importdevices
              Add devices to the devices file.

       --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'.

       -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

       PV     Physical Volume name, a device path under /dev.  For
              commands managing physical extents, a PV positional arg
              generally accepts a suffix indicating a range (or multiple
              ranges) of physical extents (PEs). When the first PE is
              omitted, it defaults to the start of the device, and when
              the last PE is omitted it defaults to end.  Start and end
              range (inclusive): PV[:PE-PE]...  Start and length range
              (counting from 0): PV[:PE+PE]...

       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

       An original VG "vg00" has PVs "/dev/sda" and "/dev/sdb".  The
       corresponding PVs from a hardware snapshot are "/dev/sdc" and
       "/dev/sdd".  Rename the VG associated with "/dev/sdc" and
       "/dev/sdd" from "vg00" to "vg00_snap" (and change associated
       UUIDs).
       vgimportclone --basevgname vg00_snap /dev/sdc /dev/sdd
