Is that the one with the plugin? Because the plugin is deprecated in RHEL and whenever you start it, it prints a noisy ERROR saying it will be removed "soon". > Which is the better architecture for a cluster I am installing mid year ? If you're planning on using RHEL6 or a derivative... pacemaker/cman/corosync.
