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.

    du -hs * won’t find “hidden” (.) files and folders, you’ll need a slightly sifferent regx (which I will leave as an exercise for you / I don’t have that info here)

    And also both du and df show different results depending on the underlying filesystem, ie btrfs (and maybe ZFS?) won’t show how much deduplication is happening.

    Also, you might be looking at sparse files too, and from memory, you’ll need another option for du or df to report those correctly.

        Nice. Glad you’re on to something.

        I can’t help you with docker files as I don’t use it, but, there’s usually a way to find out who / what owns a file, so I hope docker utils can tell you if it’s safe to delete
