Hello,
You can build a cluster with nodes on different LANs but your resource manager
must support Virtual IP addresses.
As i see in your link this is supported in the resource manager.

Ämne: Re: [Linux-cluster] CMAN nodes in different LANs
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
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.
