Arwin, Doesn't you log shows one node trying to fence the other? Clean_start prevents that at cluster startup, but on failover the survivor wants to fence the other. You may need to use fence_ack to let one node belive the other was fenced if you do not have a real fence device, for example Dell DRAC or a Network APS.

Just to let you know I managed to get the cluster in this state when I was doing some failover testing. I'm just wondering why when I do a /sbin/service rgmanager {stop|restart} it hangs indefinitely. > > Btw, a question about that clean_start directive. I'm reading the fenced man page and will the value of "1" prevent a fencing loop at startup. I've seen it where I bring up 1 node, and then bring up node 2 and node 2 fences node1 and I see this in the log: > []s, Fernando Lozano -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
