I'm assuming that the "very bad move" means that you have some PGs not in active+clean. Any non-active+clean PG will prevent your mons from being able to compact their db store. This is by design so that if something were to happen where the data on some of the copies of the PG were lost and gone forever the mons could do their best to enable the cluster to reconstruct the PG knowing when OSDs went down/up, when PGs moved to new locations, etc.
Thankfully there isn't a way around this. Something you can do is stop a mon, move the /var/lib/mon/$(hostname -s)/ folder to a new disk with more space, set it to mount in the proper location, and start it back up. You would want to do this for each mon to give them more room for the mon store to grow. Make sure to give the mon plenty of time to get back up into the quorum before moving on to the next one.
