You can check the remaining active daemons if they have pinned subtrees: ceph daemon mds.daemon-a get subtrees | jq '.[] | [.dir.path, .auth_first]' [ "/dir1/subdir1", 6 ] [ "", 0 ] [ "~mds6", 6 ] If there's no pinning enabled it should probably look like this: [ "", 0 ] [ "~mds0", 0 ] [ "/dir2", 0 ] If you mount the cephfs root directory you can check the subdirectories with getfattr: host:~ # getfattr -n ceph.dir.pin /mnt/dir1/subdir1 getfattr: Removing leading '/' from absolute path names # file: mnt/dir1/subdir1 ceph.dir.pin="1" Does that help?

I don't have a Luminous cluster at hand right now but setting max_mds to 1 already should take care and stop MDS services. Do you have have pinning enabled (subdirectories pinned to a specific MDS)?
Not on this cluster, AFAIK. How can I check that?
