Ask HN: Glusterfs or ceph on Digitalocean block storage?

I'm curious to hear of experiences running distributed filesystems like glusterfs or ceph (others too?) on Digitalocean's block storage.

I've got a side project that will be continuously adding many 50kb to 20mb files, so easy expansion is necessary.

Any "at-scale" (ie. production, under real load) performance reports/benchmarks appreciated.

Reliability, recovery from node failure, etc comments welcome.
