Looks like in this case you never actually needed what Ceph brings to the table - for a tremendous cost in complexity (and fragility, from personal anecdotal evidence) you can allow your dataset and -load to grow beyond the physical capabilities of a single node. The HA argument in less demanding settings ends up being a cargo cult mostly. Your setup will probably produce higher reliability figures than running Ceph, assuming the lack of some serious engineering capabilities.
