LVM: nome VG duplicado VolGroup00

Question

Eu estou em um servidor que mostra um nome VG duplicado. Como posso renomear um desses VolGroups para me livrar desse conflito?

Minha tentativa rápida de renomear o VolGroup (pode estar fazendo isso errado ...):

Answer 1

Da página do manual: -

"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".

... então, para o seu caso: -

vgrename zOuHvA-QTBR-wNPs-3GIQ-b2zQ-yOeH-2fBS87 newvolgroupname

... renomeará o grupo de volume com ID zOuHvA-QTBR-wNPs-3GIQ-b2zQ-yOeH-2fBS87 para newvolgroupname .

    

Answer 2

Name

vgrename - rename a volume group Synopsis

vgrename [-A|--autobackup {y|n}] [-d|--debug] [-h|-?|--help] [-t|--test] [-v|--verbose] OldVolumeGroup{Path|Name|UUID} NewVolumeGroup{Path|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

... como para

  Volume group name cciss/c0d1 has invalid characters

/dev/cciss/c0d1 não é um VG, portanto, você não pode renomeá-lo. Este é um PV no qual um VG provavelmente se baseia.
