Hi Bob,
I have not, although I started to go down that path. I had wanted
erasure coded pools but in order to front an erasure coded pool with an
RBD volume you apparently need a cache tier? Seems that doesn't give one
the performance they might want for this type of workload
(http://docs.ceph.com/docs/master/rados/operations/cache-tiering/#a-word-of-caution).
If you're OK replicating the data I suspect it might work well.
I did try sheepdog (https://sheepdog.github.io/sheepdog/) and that did
work the way I wanted it to with erasure coding and gave me pretty good
performance to boot.
