[Paul Emmerich <paul.emmerich@xxxxxxxx>]

The following RBD features are supported since these kernel versions:

Kernel 3.8: RBD_FEATURE_LAYERING  https://github.com/ceph/ceph-client/commit/d889140c4a1c5edb6a7bd90392b9d878bfaccfb6
Kernel 3.10: RBD_FEATURE_STRIPINGV2 https://github.com/ceph/ceph-client/commit/5cbf6f12c48121199cc214c93dea98cce719343b
Kernel 4.9: RBD_FEATURE_EXCLUSIVE_LOCK https://github.com/ceph/ceph-client/commit/ed95b21a4b0a71ef89306cdeb427d53cc9cb343f
Kernel 4.11: RBD_FEATURE_DATA_POOL https://github.com/ceph/ceph-client/commit/7e97332ea9caad3b7c6d86bc3b982e17eda2f736

Try using rbd-nbd if you need other features.
