I am configuring a Apache cluster on CentOS 5.5. I finished, and it worked! But there is still one problem, I can't stop cman service manual, the error message is:
"Stopping cluster:
Stopping fencing... failed

[FAILED]"
And when I fenced (manual fencing, just reboot node) the node on which service is running, it took about 10 - 20 seconds for another to take over resouces and run service. Why it's slow like that? Is there anyone has experience about it? help me, plz! Here is my cluster.conf:
