And, yes, we're running a "size:2 min_size:1" because we're on a very tight budget. If I understand correctly, this means: Make changes of files to one server. *Eventually* copy them to the other server. I hope this *eventually* means after a few minutes.
size:2 means there's two replicas of every object. Writes are synchronous (i.e. a write isn't complete until it's written to both OSDs) so there's no eventually - it's immediate.

min_size:1 means the cluster will still allow access while only one replica is available.
