<div>we kill the node with STONITH.</div>
<div>very hard for a machine to write to shared media when its powered off. </div>
<div><br> </div>
<div>we can kill nodes when:</div>- nodes become unresponsive
<div>- nodes are not part of the cluster that has quorum</div>
<div>- resources fail to stop when instructed</div>
<div>- resources fail in any way (optional) </div></div></div></blockquote>

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