NAME¶
vgimportclone - import and rename duplicated volume group (e.g. a hardware
snapshot)
SYNOPSIS¶
vgimportclone [-n|--basevgname VolumeGroupName] [-i|--import]
PhysicalVolume [PhysicalVolume...]
DESCRIPTION¶
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.
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¶
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
