I am surprised that CephFS isn't proposed as an option, in the way it removes the not negligible block storage layer from the picture. I always feel uncomfortable to stack storage technologies or file systems (here NFS over XFS over iSCSI over RDB over Rados) and try to stay as possible on the "KISS" way. Is it because CephFS is still considered as unstable or because MDS doesn't yet support HA ? (planned for Giant if I remember good).
