Hi Paul.. I have done a crm_tool leave force on the nodes in an attempt to get them to join back in, but they simply form a cluster on their own. I have asked about the igmp and have been told that it is not running on the network, Since this is a test system I have built it on ESX, one node in each of our datacenters, I am now moving both of the nodes to the same ESX server and will try again.
