We did not have any cephfs or mds involved. But since you haven’t even started a ceph upgrade in earnest, I have to wonder about your nautilus versions. Maybe you have a mismatch there?
I would definitely share the output of `ceph versions` and `ceph features`. If you’re not 14.2.22 across the board, I would at least upgrade your mon, mgr, and mds services. Then check release notes to see if there’s any clues there.

The clients says: mount error 13 = Permission denied The cephmds log: lacks required features 0x0000000000001000 client supports 0x00000000000000ff The mds/mon is still centos7/nautilus. The Clients centos7 as well. Any ideas ? Thx for suggestions and hints .
