220GB is way, way too big. I suspect your monitors need to go through a
successful leveldb compaction. The early releases of Cuttlefish suffered
several issues with store.db growing unbounded. Most were fixed by
0.61.5, I believe.
You may have luck stoping all Ceph daemons, then starting the monitor by
itself. When there were bugs, leveldb compaction tended work better
without OSD traffic hitting the monitors. Also, there are some settings
to force a compact on startup like 'mon compact on start = true' and mon
compact on trim = true". I don't think either are required anymore
though. See some history here:

My Mon store.db has been at 220GB for a few months now. Why is this and
how can I fix it? I have one monitor in this cluster and I suspect that
I can’t add monitors to the cluster because it is too big. Thank you.
