From what I have read here in the past, growing monitor db is related to not having pg's in 'clean active' state

Hi all,
I have a fairly pressing issue. I had a monitor fall out of quorum because it ran out of disk space during rebalancing from switching to upmap. I noticed all my monitor store.db started taking up nearly all disk space so I set noout, nobackfill and norecover and shutdown all the monitor daemons. Each store.db was at:
mon.a 89GB (the one that firt dropped out)
mon.a 400GB
mon.c 400GB
I tried setting mon_compact_on_start. This brought mon.a down to 1GB. Cool. However, when I try it on the other monitors it increased the db size ~1Gb/10s so I shut them down again.
Any idea what is going on? Or how can I shrik back down the db?
