There's still plenty of things to keep in mind with Gluster, though. If you use a replicated setup for redundancy, and you get a split network, you can very well end up with an inconsistent state because you can get into situations where you write to different replicas from different clients and replication doesn't succeed.

Gluster will just throw it's hands up during self-heal if that happens, and you'll need to manually resolve it.

Your filesystem structure won't break, but your files certainly can.
