We decided to stop using the posix filesystem, and as such have
stopped running ceph-mds (and removed the mds things from ceph.conf).
However we get warnings about the missing mds when running 'ceph
health'.
How do I delete all the mdses? I tried 'ceph mds rm <mdsname>' but
that doesn't seem to do any good.

This is a stupid question, but, did you stop and restart the cluster
after editing ceph.conf?

The 'rm' refuses to do it if it is in use. Instead,
- make sure the ceph-mds daemon(s) aren't running
- ceph mds newfs metadata data
That will blow away the old mdsmap (and fs metadata!). Until a new
'first' ceph-mds starts up, ceph health won't complain.
