Hi Guys
I have a server with several HDD and created a LVM disk. Now I receive a error message at Webmin that my / has only 98 MB free space. Here is a DF -H output:
root@srv01:/# df -h
Dateisystem Größe Benutzt Verf. Verw% Eingehängt auf
udev 59G 0 59G 0% /dev
tmpfs 12G 138M 12G 2% /run

tmpfs 5.0M 0 5.0M 0% /run/lock
tmpfs 60G 0 60G 0% /sys/fs/cgroup

/dev/mapper/srv01--vg-home 103G 60M 98G 1% /home

tmpfs 12G 0 12G 0% /run/user/1000
/home/dblake/.Private 103G 60M 98G 1% /home/dblake
At the moment I can’t see where this space is left. I tried several tricks to clean up space:
apt-get autoremove -purge
But still there is no space left. As I use this server also as Plex Media Server I’m not able to stream now. (All films are located at a own HDD /storage/Plex)
Anybody has some tips for me?
Thanks

You just need to chase down where the space has gone and fix it. No magic bullet for this.
Use du to spelunk into it and figure it out. I usually use this incantation:
# du -xh --max-depth=2
-x tells du to not cross onto other filesystems (so you’re only checking /), and -h is just a convenience to get the sizes in human readable format. --max-depth is how many directories to dig down into. I start with 2, because otherwise I end up with too much noise. You may need to cd into your biggest directories and do a more specific search.
95G is obviously not just packages; there’s some kind of non-system files or logs or something that are huge. I’d suspect a runaway log, or maybe root email (receiving some sort of system notification, probably indicating some sort of misconfiguration).

Hi Joe
Thanks for this explanation - the problem is that I can see that there are many directories which includes many files … but in summary there are only 32GB if I read the output correctly:

Also changing from max-depth=2 to 4 doesn’t show me any larger files …
