ok so it seems i am missing something here. lets take an example of two nodes cluster. my understanding is , pacemaker cluster will be using one network (bind nw interface) for heartbeat and if it fails then it , both node will be in split brain situation and both will try to fence each other. now for fencing if we are using ilo then , it will be using entirely different network and this way it shoud work . if ilo network becomes down , then off course the stonith will not work. and this will be second failure. here our goal is to prevent single point of failure. so the above thing should be independent of distance, in spite of we are having local cluster , or extended cluster (whose nodes are spanning across multiple sites) , the stonith behavior should be same. am i wrong?? > _______________________________________________ > Pacemaker mailing list > Pacemaker@oss.clusterlabs.org > http://oss.clusterlabs.org/mailman/listinfo/pacemaker >
