For an explanation of ranks etc see http://docs.ceph.com/docs/master/cephfs/standby/ Note that if the daemon is still running then you'll find it immediately appears in the map again. If you want to permamently remove an MDS daemon on a particular server then you need to go and do that on the server (or modify whatever configuration management solution you're using).
