Two node cluster, start CMAN fence the other node
Hi,all
I'm trying to install my first cluster of two nodes, using IPMILAN fence devices. I need some help because I can't find what I've missed.
My main problem is that the "service cman start" reboots the other node and I can't form the two nodes cluster.
I'm using nodes named separately fsommfe01 and fsommfe02, they are on the same VLAN and pings each other ok

When I start the cman service, it hangs up for some time at the "Starting fencing..." step and after those configured 10 secs it fences fsommfe02 and reboots it.

Here are my questions;
I can't get the two nodes, joining the cluster...
I guess I'm missing something at the cluster.conf file??? I can't find what I'm making wrong.
In my test envrionment,the two nodes connecting the switch to deliver the heartbeat,if my switch fails, I think the two nodes will think the opposite as dead and fence it. and method to solve this? if it's yes any guide given to me to follow?/thank you very much;
My os version is RHEL5.2, my friend told me if my cluster software version is lower or equal to 5.3,upgrade it to 5.3 from RHN,does it true???
My sincere thanks
Thanks for any help!
