1) well if somehow STONITH fails to kill the errant node and the node is
still alive , it will be able to do IO on shared disk.   this can cause data
integrity issue right??

2) suppose we have set STONITH action to reboot then the errant node can
comeup and still write to shared disk , even if it does not suppose to do
this.

if openais -pacemaker provide something  for resouce fencing we would have
completely ruled out  above possiblities  Please share your view.




   i am sure you ppl must have something .
