Yes, there is. Using ceph-objectstore-tool you are able to rebuild the MON database. BUT, this isn't something you would really want to do as you loose your cephx keys and such and getting them all back will be a total nightmare. My advice, make sure you have reliable hardware for your Monitors. Run them on DC-grade SSDs and you'll be fine.
