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 . > > waiting for your reply, >>>> Thanks >>>> _______________________________________________ >>>> Pacemaker mailing list >>>> Pacemaker@oss.clusterlabs.org >>>> http://oss.clusterlabs.org/mailman/listinfo/pacemaker >>>> >>> >> >> _______________________________________________ >> Pacemaker mailing list >> Pacemaker@oss.clusterlabs.org >> http://oss.clusterlabs.org/mailman/listinfo/pacemaker >> > > _______________________________________________ > Pacemaker mailing list > Pacemaker@oss.clusterlabs.org > http://oss.clusterlabs.org/mailman/listinfo/pacemaker > > > > > _______________________________________________ > Pacemaker mailing list > Pacemaker@oss.clusterlabs.org > http://oss.clusterlabs.org/mailman/listinfo/pacemaker > >
