While it's certainly not ideal, of the available options I prefer
cephfs.  You get full functionality unlike going through cinder and I
wouldn't trust the new iscsi gateway functionality for any kind of
redundant gateway usage yet.  Direct native rbd access would certainly
be preferred but unfortunately I just don't see it coming.  Once upon a
time there was hope but then the cinder bandaid arrived and that pretty
much killed it.
