Please don’t fixate on just the bash output I posted. I assure you I have run `docker system prune -a -f --volumes` ` docker builder prune -f` etc. unmounted any overaly2 mounts. I’ve made sure there is nothing left in docker, but /mnt/docker\_storage/overlay2 still takes up a huge amount of space.
