The answer is given at http://docs.ceph.com/docs/nautilus/rados/operations/erasure-code/#erasure-coding-with-overwrites "... Erasure coded pools do not support omap, so to use them with RBD and CephFS you must instruct them to store their data in an ec pool, and their metadata in a replicated pool ..." Another option is using tiered pools, specially when you can dedicate fast OSDs for that: http://docs.ceph.com/docs/nautilus/rados/operations/erasure-code/#erasure-coded-pool-and-cache-tiering -- End of message.
