BackupPC and Ceph sounds like an interesting combination. Other than this hanging MDS problem, what are your experiences with that? I'm asking because BackupPC is the only application I know of that actually makes heavy use of hardlinks. Ceph, as far as I've understood it, supports hardlinks, but works under the assumption that they're a rare and not performance-critical corner case, and does some optimizations that help the more common cases, but would probably hurt if you are using hardlinks a lot.
