It's better to selectively require some features. See also: https://docs.ceph.com/en/latest/cephfs/administration/#minimum-client-version The upstream documentation could be improved some in that we should no longer be mentioning `min_compat_client` (it should be deprecated). Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
