I have two back-end databases, one load balancer, and one replicator. I've been testing failover and rebuilding a degraded cluster, and I'm finidng that it is REALLY easy for the two back-ends to get out of sync with each other. This is very disturbing. I was wondering if anyone has experience with solving this problem.
