Ráadásul: "I have touched on quorum device above but not mentioned it at all otherwise. With all of the above new options it's hoped that most installations will no longer need qdiskd to get the functionality they need from the cluster, and thus life should be a lot simpler. For those few poor souls that do need to use qdiskd still, err ... it's not there yet! Sorry." :)
