Your MDSMap compat is probably what's preventing promotion of standbys. That's a new change in master (which is also being backported to Pacific). Did you downgrade back to Pacific? Try: for i in $(seq 1 10); do ceph fs compat <fsname> add_incompat $i; done
I have a similar situation after upgrading to 16.2.6 on my test cluster. The three MDSs will not become active but stay in standby.
