From personal experience: A two node volume can get you into trouble when one of the nodes goes down unexpectedly/crashes. At the very least, you should have an arbiter volume (introduced in Gluster 3.7) on a separate physical node.
I've introduced a third node for full replica 3 now. Surprised and pleased that there is no real performance drop.
This is where the docs get a bit frustrating :( https://gluster.readthedocs.org/en/release-3.7.0/Features/server-quorum/ discusses server quorum and the settings, but doesn't say what the default values are, and there is no way of reading volume settings in gluster.
