Re: [linux-lvm] LVM help needed: conflicting names

have you tried:

$ man vgrename

       vgrename - rename a volume group

       vgrename renames an existing (see vgcreate(8) ) volume group

       "vgrename /dev/vg02 /dev/my_volume_group" renames existing volume 
group "vg02" to "my_volume_group".

       "vgrename vg02 my_volume_group" does the same.
