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.

Sorry I believe I wasn't actually in the root of the drive! 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.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
