This one I do not understand. E.g. consider 3 seconds timeout. Both servers are down. Server is powered on. Pacemaker on server 1 waits 3 seconds for other cluster nodes, then it starts as single node. Now server2 boots and pacemaker on server 2 will find the existing node and join it. Of course, for example if the network is down when both servers are booting, then I will have 2 single-node cluster. But that would also happen if the network gets partitioned later. regards Klaus _______________________________________________ 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
