I noticed the root drive of my home server (Debian) is at 99% capacity, which was odd to be because I don’t store anything on the root ssd. sudo df -h confirms that 99% of my 256gb drive is full. But sudo du -sh * all added up, only comes to about 30gb.

This is a pc that only runs docker containers and one virtual machine for home assistant. And yes I have restarted, Any ideas as to how to find the missing 200+ gigabytes?

EDIT: sudo ncdu allowed me to find a 72gb [long string of characterless]-json.log file in /var/lib/docker/containers and many 1gb+ files in /var/lib/docker/overlay2. I’m not sure what to do with this information (or what’s safe to delete) but I’m getting somewhere.
