The original poster was asking how to delete an MDS so that he could move it to another server, presumably he doesn't also want to lose all his files. Sebastian's guide only mentions newfs because he's talking about permanently removing the last MDS when CephFS is not in use. Anyway: to use a different server for your MDS, simply create your new MDS (e.g. ceph-deploy mds create [mynewhost]), stop the old MDS (e.g. stop ceph-mds-all), and prod ceph to start using the new one (ceph mds fail 0). Now you're using your new MDS, and can clean up the old MDS at leisure. ceph-deploy doesn't have support for this yet, so you'll probably just remove the /var/lib/ceph/mds/<your-mds-id> directory on the old server and be done.
