[Linux-cluster] fencing issue in 2 nodes cluster

[AKIN ÿffffffffffd6ZTOPUZ]

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?
 
 
Regards
