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
