Think of multicast as a sort of "mailing list"; A machine "subscribes" to the multicast group and the switch then says "right, when a packet comes in addressed to the multicast group, forward a copy to all subscribed machines". With Cisco, you need to create persistent multicast groups in the switch, if I recall correctly (I don't use Cisco myself). In your case though, you're showing "<a href="http://cgceccprd1.combinedgroup.net" target="_blank">cgceccprd1.combinedgroup.net</a>" as "Offline" from both nodes, so the cluster is simply not starting. Can you paste your cluster.conf please? Also, can you run 'tail -f -n 0 /var/log/messages' in a terminal on cgceccprd1, try to start the cluster, wait for it to fail and then paste the output along with your configuration? This might help (the "Overview" section at the start, if nothing else). There is a sample cluster.conf there. <a href="https://alteeve.ca/w/2-Node_Red_Hat_KVM_Cluster_Tutorial" target="_blank">https://alteeve.ca/w/2-Node_Red_Hat_KVM_Cluster_Tutorial</a> hope that helps -- Digimer Papers and Projects: <a href="https://alteeve.ca" target="_blank">https://alteeve.ca</a> </blockquote></div> </div>
