vgimportclone

import and rename duplicated volume group (e.g. a hardware snapshot)

vgimportclone [-n|--basevgname VolumeGroupName] [-i|--import] PhysicalVolume [PhysicalVolume...]

vgimportclone is used to import a duplicated VG (e.g. hardware snapshot). Duplicate VG(s) and PV(s) are not able to be used until they are made to coexist with the origin VG(s) and PV(s). vgimportclone renames the VG associated with the specified PV(s) and changes the associated VG and PV UUIDs.

See lvm(8) for common options.
-n
, --basevgname VolumeGroupName

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.

-i, --import

Import exported Volume Groups. Otherwise VGs that have been exported will not be changed (nor will their associated PVs).

LVM_BINARY

The LVM2 binary to use. Defaults to "lvm".

The origin VG "vg00" has origin PVs "/dev/sda" and "/dev/sdb" and the respective snapshot PVs are "/dev/sdc" and "/dev/sdd". To rename the VG associated with "/dev/sdc" and "/dev/sdd" from "vg00" to "vg00_snap" (and to change associated VG and PV UUIDs) do:

vgimportclone --basevgname vg00_snap /dev/sdc /dev/sdd
