Hmm, what issues did you run into? I've used it on a few projects in a mirrored way and it was always fine. Is the clustering the issue?

Not OP, but that is my experience. It worked like a rock on a single server. Clustering brought us issues rooting from its complexity. Split brain scenario, corruption of the Mnesia database and such. We went back to single server mode.

Same! Never bothered with the so-called HA setup after running a cluster for few months. Making all messages durable + backups of underlying storage are sufficient, while the do not prevent an outage, at least bringing the system back to an operational state is fairly straightforward

Is Mnesia just terrible or is there some trick? I did run into issues you're talking about with ejabberd clusters.
