If your wanting to add a new disk to the same volume group and use it then no you don't need to rename anything, you can use the vgextend command after running pvcreate on the new disk to extend the existing volume group to the new disk. If your wanting to add an existing disk to a system that already has a conflicting volume group name in it, then yes you'll need to vgrename one of them so they do not conflict. nate
