vgimportclone - import and rename duplicated volume group (e.g. a
vgimportclone [-n|--basevgname VolumeGroupName] [-i|--import]
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 for common options.
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.
Import exported Volume Groups. Otherwise VGs that have been
exported will not be changed (nor will their associated PVs).
The LVM2 binary to use. Defaults to "lvm".
If origin VG test_vg has PVs /dev/loop0 and /dev/loop1 and /dev/loop2
and /dev/loop3 are respective snapshot PVs of the origin PVs. To
rename the VG associated with /dev/loop2 and /dev/loop3 from test_vg to
test_vg_snap (and change associated VG and PV UUIDs):
vgimportclone --basevgname test_vg_snap /dev/loop2 /dev/loop3
