    keyring = /var/lib/ceph/mds/ceph-$id/keyring

So it will work for every MDS that you setup. Besides that, no extra
options would be needed for MDS to start.

More then the bellow lines should not be needed to get the mds started.

mkdir -p /var/lib/ceph/mds/ceph-$SERVER
chown -R ceph:ceph /var/lib/ceph/mds/ceph-$SERVER
ceph --cluster ceph --name client.bootstrap-mds \
--keyring /var/lib/ceph/bootstrap-mds/ceph.keyring auth \
get-or-create mds.$SERVER osd 'allow rwx' mds 'allow' mon 'allow profile mds' \
-o /var/lib/ceph/mds/ceph-$SERVER/keyring

If it's not working, whats the output of 'systemctl status
