NewVolumeGroup{

Name}
DESCRIPTION¶
vgrename renames an existing (see
vgcreate(8)) volume group from
OldVolumeGroup{
Name|
Path|
UUID} to
NewVolumeGroup{
Name|
Path}.
All the Volume Groups visible to a system need to have different names.
Otherwise many LVM2 commands will refuse to run or give warning messages.
This situation could arise when disks are moved between machines. If a disk is
connected and it contains a Volume Group with the same name as the Volume
Group containing your root filesystem the machine might not even boot
correctly. However, the two Volume Groups should have different UUIDs (unless
the disk was cloned) so you can rename one of the conflicting Volume Groups
with
vgrename.
OPTIONS¶
See
lvm(8) for common options.
Examples¶
Renames existing volume group vg02 to my_volume_group:
vgrename /dev/vg02 /dev/my_volume_group
or
vgrename vg02 my_volume_group
Changes the name of the Volume Group with UUID
Zvlifi-Ep3t-e0Ng-U42h-o0ye-KHu1-nl7Ns4 to VolGroup00_tmp:
vgrename Zvlifi-Ep3t-e0Ng-U42h-o0ye-KHu1-nl7Ns4 VolGroup00_tmp
