Disk full but du shows approx 14GB free [SOLVED]

ZeroGrav · 06-13-2011, 03:09 PM

I shared a folder on my system through Samba. After a while my disk became full and I did a cut - paste of the files through Webmin File Manager to an external USB-drive.

The problem is that source files are gone but the free space is still 0.

I have tried reboot, forced fsck at boot but none has helped.

Output from df -h:

Code:

Filesystem            Size  Used Avail Use% Mounted on
/dev/sda1              15G   15G     0 100% /

Output from du --max-depth 1 -c -h

14M     ./boot
143M    ./var
0       ./sys
15G     .
15G     total

The 14GB listed in ./media is the USB-stick where I pasted the files, I have tripple checked it already.

What else can I do? The files should be unlocked after reboot right? lsof doesn't show anything related to this.

Please help!!

On ext partitions, 5% is reserved for system use in cases like this. Use 'sudo tune2fs -l /dev/sda1' for a rundown on what is going on with the partition.

From the du output, I think you need to run that with the USB stick removed (and any other storage devices as well) so you can see space utilization on the root partitions and not on other mounted file systems. It almost looks like you have a subdirectory under /media that is being used as both a storage area and as a mount point and that could confuse things.

/media is not reported in the df output..

could you try "df -hP" and paste the results here..
Also use fdisk -l

Thanks for helping out!

Did an extra check and it turns out that Webmin shows that the external USB-stick is mounted to /media/usb1 but it turns out that it was not mounted at all. What I actually did was to copy files from /media/usb0 to /media/usb1, both residing on the root file system.

How can I find out where /media/usb0 and /media/usb1 are located in the filesystem?

df -hP /media/usb0 /media/usb1

The above command will show you in which filesystem the directories are residing.
