I should also add that the best practice for setting up the Clusters on RHEL 5 is using Ricci and Luci (Red Hat has docs on it if you want to glance at what that is) as some of the other methods are deprecated (ie system-config-cluster, etc.). This isn't to say that you shouldn't hand edit you cluster.conf, but start the basics of your config using Ricci and Luci, then tweak away.<div>

Is the clustering feature of Red Hat / Centos used in the real world, or<br>
