Ubuntu

Bad partition free space size

Asked by peter07

Something is wrong with my 8.10 installation. Ubuntu gets bad system partition (/dev/sda2) free space size. I can't use system right now.

If I type df - h I get :
~$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 9,7G 9,6G 0 100% /

which is wrong result.

I'm almost sure, that I have few GBs free space there. I checked it using baobab from LiveCD. Analyse result showed 5GB free space on /dev/sda2. I tried fsck, resize2fs, e2fsck (with badblock check) with no positive result :/. What is going on?

Please try to check your filesystem...

Force filesystem check

Please open a Terminal from the menu Applications → Accessories → Terminal and type:

sudo touch /forcefsck

give your user password when requested, you don't see nothing when you type it, then press enter.

Then reboot your pc the filesystem will be checked...

Hope this helps

I tried to check my filesystem. I checked your solution - no result still df output is wrong - no free space for system. Like I wrote before I also tried other tools: fsck, resize2fs, e2fsck (with badblock check) from Ubuntu LiveCd. I didn't receive any error messages.

I dont know what's happen for you, but you can try to check where this "used" space is...
open a Terminal and try :
cd /
du -khs *

what the system is showing?

You're right - there must be a bug in baobab application. It doesn't show backups from /var/backup and I don't know why? du command helps me find those big files. Thanks for help.

There's also a graphical du called "Disk Usage Analyzer" which shows where everything is being used pretty neatly in a pie form.
