Actually, I already have recovered OSDs and MON daemon back to the cluster according to http://ceph.com/docs/master/rados/operations/add-or-rm-osds/and http://ceph.com/docs/master/rados/operations/add-or-rm-mons/ .
But doc has missed info about removing/add MDS. How I can recovery MDS daemon for failed node?
