|
|
.SH DESCRIPTION
|
|
vgrename renames an existing (see
|
|
.B vgcreate(8)
|
|
) volume group from
|
|
.IR OldVolumeGroup { Name | Path | UUID }
|
|
to
|
|
.IR NewVolumeGroup { Name | Path }.
|
|
.SH OPTIONS
|
|
See \fBlvm\fP for common options.
|
|
.SH Examples
|
|
"vgrename /dev/vg02 /dev/my_volume_group" renames existing
|
|
volume group "vg02" to "my_volume_group".
|
|
.TP
|
|
"vgrename vg02 my_volume_group" does the same.
|
|
.TP
|
|
"vgrename Zvlifi-Ep3t-e0Ng-U42h-o0ye-KHu1-nl7Ns4 VolGroup00_tmp"
|
|
changes the name of the Volume Group with UUID
|
|
Zvlifi-Ep3t-e0Ng-U42h-o0ye-KHu1-nl7Ns4 to
|
|
"VolGroup00_tmp".
|
|
|
|
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
|
|
\fBvgrename\fP.
