You can manually extract, edit, and inject the mon map to manually fix it. In this case you probably need to:
1. check what exactly is going on, inspect the mon map of all mons 2. maybe the IP addresses changed or something? see if you can fix it somehow without editing the monmap 3. adjust the mon map accordingly and inject it back into 2 mons You can use these instructions to get/set/edit the mon map: http://docs.ceph.com/docs/mimic/rados/operations/add-or-rm-mons/#removing-monitors-from-an-unhealthy-cluster Paul Am Do., 4.
