I'm using clvm and want to activate all available volume groups as soon as clvm comes up. It simplifies the configuration if I can handle multiple groups in the same pacemaker primitive. My Xen primitives depend on the LVM primitive that hosts their filesystem. It's possible a Xen VM might depend on a volume from more than one volume group, or an admin might decide to move a VM from one VG to another. Supporting multiple VGs in the LVM primitive means I can still require storage to be available before starting a VM, without coupling my pacemaker configuration so tightly to the storage layout. > Many thanks for the contribution, but I can't accept it as is nor > comment.
