Disk suddenly full, no idea why

mir91 · 2014-09-12 18:21:58

On the home partition I had like 8 GB free space, now all of a sudden 100% is used! I have no idea why and by what.
How can I find out what happened there? I'm completely stumped.

There are few tools for this. Look in your journal, use ncdu to see what is taking up space, etc

Not a Sysadmin issue, moving to NC...

I do it the stupidly simple way: "du -sh /*" (Use "man du" to find out what it does.) Find out which directory is taking up the most space, then "drill down", if you follow my meaning.

If the drive is too full to even boot, just boot from a live disc and mount the drive.

I would recommend kdeutils-filelight for this.

Thanks, I ended up using

find /home -mtime -1 -ls

and it seems it's from game updates in Steam.

So checking if there is enough space before downloading is too advanced/complex for Steam developers? Must be an obvious oversight. Maybe you can inform them about this, but make sure it does not prevent the user from downloading, only warns/informs him.

Could be due to coredumps? I had 700MB used all of sudden and then realized that it was coredump.

Check: /var/lib/systemd/coredump

man coredump.conf

Nice, I had 2GB coredumps just from "Brasero" it seems, weird stuff..

Just FYI, ncdu is a great lightweight util for this task as well. As an aside, limit coredumps in the future in /etc/systemd/coredump.conf and see the coredump.conf man page.
