With the two interfaces on different subnets, you might be able to get it to seem to work, but you won't get failover if one interface fails. Specifying multicast only affects the way cman communicates - DLM uses TCP connections based on the address passed down by cman. IP4/6 - it makes no difference. In short: if you need interface failover with cman/dlm, you need to use bonding - with all that that implies. -- patrick -- Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
