Depending on your server load, it could be reasonnable to set up
your cluster to rsync every 5 or 10 min via a dedicated ethernet
link (cross cable). Heartbeat would manage ip takeover.

Something like ldap replication would be great. It could be done
by configuring the smtp server to duplicate incoming and outgoing
