Lots. CephFS takes advantage of almost every RADOS capability, and EC pools support only a subset of that. We haven't even whiteboarded what would be required at this time. If using a cache pool is a feasible option that would be a lot easier, but we haven't evaluated it yet. -Greg Software Engineer #42 @ http://inktank.com | http://ceph.com > > In our case we'd like to take advantage of the savings since a large > chunk of our data is written once, read many times, after a while > seldom accessed.
