I was able to successfully configure MySQL master-master replication and RabbitMQ clustering to start toying with a HA Baruwa setup, but has anyone else experienced problems when replicating certain tables that utilize the msg IDs as the PK [as opposed to an auto-increment PK]? I'm wondering if it's still a better route to pursue DRBD+Pacemaker/Heartbeat rather than relying in MySQL replication... the biggest benefit to using MySQL replication is distribution of redundant servers, whereas the virtual IP shared between nodes in a DRBD cluster could limit where I can place offsite nodes...
