One thing I was wondering is how the cluster knows which network interface should get the cluster service IP address in that situation. Right now, I don't have anything in my cluster.conf that specifies this, but it just seems to work. I figured that if I tried to use a crossover cable, what I would need to do is use /etc/hosts to create hostnames on this little private network (consisting of just the 2 nodes connected by a cable) and use those hostnames as the node hostnames in cluster.conf. If I did that, would the cluster services try to assign the cluster service IP to the interface with the crossover cable (when obviously what I want is to assign it to the outward-facing interface)? -Andrew L -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
