Hi
thanks all repilies
I added verbose parameter into fence agent line in cluster.conf according to Heiko (verbose="true",method="onoff")
and I read the web link sent by Digimer .I tested fencing using "echo c > /proc/sysrq-trigger" on node1.
after that I saw fencing occured and related services moved to other node properly.
in this
case can we say , fencing is ok ? or also should I use fence_node command on node for being sure?
