Disk free result "df" differs from "du"


Hi,
the command "df -h" reports 101G whereas "du -h --max-depth=1" reports 62G on my partition /data (ReiserFS, size 104G, raid5) running on a file server with Suse 10.0.
Total number of files: 152412
Number of small files (< 5k): 73573
Where is the rest of disk space (39G) ?

df reports on the whole partition

du reports on the disk space used by specific files / directories

What is the complete output of df?---ie Size, Used, Avail

Files might have been deleted, but might still be 'in use' by processes. That can explain the difference and a reboot should solve that.

If you know which files are 'involved', you can find the responsible process with the lsof command and stop/start that process which also should clear the situation.

Hi pixellany,
thanks for your quick answer !

Here is the complete output of df -h
Size = 104G
Used = 100G
Avail = 3.6G
Use% = 97%
Mounted on: /data

So partition is nearly full.

Hi Wim,

thanks for you quick answer !

I will do a reboot on that machine cause I do not know what files are involved.

Yesterday I did the reboot, here the results:
linux starts in maintenance mode
reiserfsck --check reports exit-code 4
reiserfsck --rebuild-tree runs pass 0, 1 but does not finish pass 2
reboot and run rebuild again for three times with the same result: hang in pass 2
support for ReiserFS no longer available (www.namesys.com)
format with Ext3, restore data from backup

I hope Raid5 will run better on Ext3, ...
