In order for the node to be quorate (and start services) with two_node="1", the nodes must generally be able to fence each other. I don't know how this could have happened in your cluster - so there are two problems: (a) The nodes don't see each other (b) Fencing completes somehow; but we don't know how (yet) So, the next thing to do would be to produce the problem and capture the output of: cman_tool nodes cman_tool services Also, if you're using RHEL4 (which I assume based on a RHEL4 documentation manual you noted in an earlier email), you can try to force multicast on a particular address + interface: ... <clusternodes> <clusternode name="corviewprimary" votes="1" nodeid="1"> <multicast addr="225.0.0.12" interface="bond0"/> <fence/> </clusternode> <clusternode name="corviewsecondary" votes="1" nodeid="2"> <multicast addr="225.0.0.12" interface="bond0"/> <fence/> </clusternode> </clusternodes> ... -- Lon -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
