Hi Digimer, You are correct. I do need to configure fencing. But before fencing, I need to have these servers become member of cluster first. If they are not member of cluster set. Doesn't matter I try to configure fencing or not. My cluster won't work. Thanks for your help.

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. >> >> On 07/01/15 04:29 PM, Cao, Vinh wrote: >>> Hi Digimer, >>> >>> Here is from the logs: >>> [root@ustlvcmsp1954 ~]# tail -f /var/log/messages >>> Jan 7 16:14:01 ustlvcmsp1954 corosync[8182]: [SERV ] Service engine loaded: corosync profile loading service >>> Jan 7 16:14:01 ustlvcmsp1954 corosync[8182]: [QUORUM] Using quorum provider quorum_cman >>> Jan 7 16:14:01 ustlvcmsp1954 corosync[8182]: [SERV ] Service engine loaded: corosync cluster quorum service v0.1 >>> Jan 7 16:14:01 ustlvcmsp1954 corosync[8182]: [MAIN ] Compatibility mode set to whitetank.
