Hi Digimer,

Yes, I just did. Looks like they are failing. I'm not sure why that is.
Please see the attachment for all servers log.

By the way, I do appreciated all the helps I can get.

Quorum is enabled by default. I need to see the entire logs from all five nodes, as I mentioned in the first email. Please disable cman from starting on boot, configure fencing properly and then reboot all nodes cleanly. Start the 'tail -f -n 0 /var/log/messages' on all five nodes, then in another window, start cman on all five nodes. When things settle down, copy/paste all the log output please.
