NAME
vgimportclone - import and rename duplicated volume group (e.g. a hard‐
ware snapshot)
SYNOPSIS
vgimportclone [-n|--basevgname VolumeGroupName] [-i|--import] Physi‐
calVolume [PhysicalVolume...]
DESCRIPTION
vgimportclone is used to import a duplicated VG (e.g. hardware snap‐
shot). 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.
OPTIONS
See lvm 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).
ENVIRONMENT VARIABLES
LVM_BINARY
The LVM2 binary to use. Defaults to "lvm".
EXAMPLES
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
