Hi Just for information, I wonder if this behavior is normal : I have a two-nodes cluster with a quorum disk, and the CS5 is started on both nodes with a service on each one. Quorum is working fine when I break the quorum disk format (with a mkfs on the device !) so that mkqisk -L returns none. The behavior is : the CS5 is always working fine as if nothing has happen. I wonder if it is only due to the heuristics or if this behavior is simply the std behavior of CS5 with regard to the quorum disk ?
