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. df -h confirms that 99% of my 256gb drive is full. But 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?

    To help you we need to understand your setup

    • show us the output of ‘mount’
    • show us the output of ‘lsblk’
    • show us the output of ‘fdisk -l /dev/sda’
    • Do you run snapshots?

      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.

      mount outputted a lot of text. I suspect this may be getting somewhere but I’m not too experienced. There is a lot of overlay on /var/lib/docker/overlay2/[long string of numbers and letters]. I also see a lot (~25) of nsfs on /run/docker/netns/[string of letters and numbers] type nsfs (rw)

      lsblk game me my drives as expected, and fdisk gave fdisk: command not found.
