Sorry I did not give much context of what I'm trying to do. I'm trying to set up a cluster of nodes running apache qpid as mentioned in the documentation here<http://qpid.apache.org/books/trunk/AMQP-Messaging-Broker-CPP-Book/html/chap-Messaging_User_Guide-Active_Passive_Cluster.html> The documentation says that cluster mechanism uses cman and rgmanager but does not directly depend on openais or corosync and does not use multicasting. It also says "Replication to a *disaster recovery* site can be handled as simply another node in the cluster, it does not require a separate replication mechanism" . I think by "disaster recovery site" it means a different network. I'm very new to clustering so I just wanted to know if it is possible to use cman and rgmanager with cluster nodes in different networks.
Thanks, Terance.
