It's a while since I've done some pacemaker testing, but yesterday I've done a setup of KVM guests on top off DRBD volumes This without using shared storage or cluster file systems. (2-node cluster)
I like this setup because it allows applications that can't be clustered easily to run in an VM. Live migration is not necessary, but fast recovery is necessary. The problem: some guests don't boot after a "migrate" or "standby". Also cutting the connection on one of the nodes doesn't work that wel for the moment. It's no problem to recover these guests manually, but this way it doesn't behave like a cluster Maybe I've to tweak some parameters/ordering/colocation/.... ? Or do I really need shared storage? Or.... _______________________________________________ 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
