My experience with system-config-cluster and luci/ricci and RHEL5 was disappointing. I ran system-config-cluster and created a small test cluster. When I ran system-config-cluster again, it said there were no members in the cluster, but it did show the nodes. It never showed the "Management" tab. I could run commands like "clustat" and "cman_tool status", I would see all the nodes in my test cluster. I opened a case with Redhat, and they did not respond until I escalated the case with a Redhat Rep. Even then, the engineer asked me if I was sure all my daemons were running, and the Redhat Rep told me I needed to go to training. An update came out for luci, ricci, and system-config-cluster, and suddenly system-config-cluster worked better, and it would see the cluster it created. Everything seemed to work fine, until I wanted to make changes. I changed the IP addresses of the three cluster nodes, and the cluster freaked out and kept rebooting nodes on its own. I unmounted a gfs2 filesystem and had the same behavior. I had to boot one of the nodes with a rescue disk and do a "chkconfig cman off" before it would boot again. I decided that the Cluster Suite for RHEL5 is not ready for production. Redhat says I need to go to training. Now, to answer your question about removing a cluster made by luci, go to the Web interface, and under the "Homebase" tab, go to "Manage Systems" and you should see a box on the right that says "Remove clusters and systems". You should be able to click on your cluster and then click "Remove slected entries" and remove the cluster. ______________________________________________________________________________ This email is intended solely for the person or entity to which it is addressed and may contain confidential and/or privileged information.
