vgrename(8)


NAME

   vgrename --- rename a volume group

SYNOPSIS

   vgrename   [-A|--autobackup   {y|n}]   [--commandprofile   ProfileName]
   [-d|--debug] [-h|-?|--help] [--reportformat  {basic|json}]  [-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
