rootfs full

rob · Oct 11th 2015

Hello

It appears, my external USB drive was dismounted and so a backup was made to my system drive. The drive now is full and I can't login via WebGUI anymore.

df -h:

It appears, the issue is with "/dev/disk/by-uuid/b6c50d69-28de-4e28-be51-d6c698098642", but as a Linux Noob, I have no idea, how do access/delete the backup data written to this drive... Appreciate any help!!!

Thanks,
Rob

Do this to free up some space:

apt-get clean
rm /var/log/*gz

The give results of this command:

du -a /var | sort -n -r | head -n 10

tekkb,

Thank you for your reply!

I ran apt-get clean and removed the log files, but still can't log in to the web interface. I enter my login credential and am automatically redirected to the login page again, without any error message.

Here the result for "du -a /var | sort -n -r | head -n 10":

Code

537208  /var
349824  /var/lib
102516  /var/lib/clamav
97348   /var/log
83112   /var/lib/apt
83052   /var/lib/apt/lists

68700   /var/lib/squeezeboxserver/cache
67068   /var/tmp
63204   /var/lib/clamav/main.cvd

Looking at the "df -h" output in my first post, disk "/dev/disk/by-uuid/b6c50d69-28de-4e28-be51-d6c698098642" - which is my OS disk - has used up all of its 14G. But neither with MC nor with the "find" command can I find the files taking up all the space on this disk... Where have the files been backed up do?

Never mind, I was able to solve the problem!

The backup was saved to /media/1DC504B8290910E4 which is the path to my USB drive. Since the drive wasn't mounted, the data was written to the OS disk under that path, instead of the USB drive. Unmounting the USB drive and then deleting the files under "media/1DC504B8290910E4" did the trick to get my rootfs space back...

Cheers!
Rob
