I'm a newbie with pacemaker, so take my advice with that in mind. > Since I use Lighty as a load balancer, it is tied with my public > IP.

So if the ping node goes down, then lighty_group will be shut down everywhere. I'm not certain on how to improve this situation, since I'm having trouble with a similar configuration. In principle you should be assigning a positive score to nodes that can ping, so that you don't assign negative scores. As far as I know only negative scores can cause pacemaker to shut down a resource. ~David _______________________________________________ Pacemaker mailing list: Pacemaker@oss.clusterlabs.org http://oss.clusterlabs.org/mailman/listinfo/pacemaker Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://developerbugs.linux-foundation.org/enter_bug.cgi?product=Pacemaker
