Disk quota exceeded (difference btw. du and df, again!)
I haven't been able to do anything since yesterday evening because my account is full to the brim. Very annoying on a Friday evening when no admin will be in until Monday morning. Of course, I might consider cleaning up if I knew where the problem is, but I can't figure it out because du and df give me so widely differing numbers:

Code:
~$ df -h .
Filesystem            Size  Used Avail Use% Mounted on
nfs-server:/misc-home-1/myuser
                       11G   11G     0 100% /home/myuser
~$ du -sh
72M    .

I read an article or two explaining the reason for the difference, but I've logged out in the mean time & ps doesn't show any "interesting" running processes that might have files open:

Code:
~$ ps -ef | grep myuser
myuser    1688 31169  0 15:22 pts/1    00:00:00 ps -ef
myuser    1689 31169  0 15:22 pts/1    00:00:00 grep myuser
myuser    1691 31169  0 15:22 pts/1    00:00:00 sed s/myuser/myuser/g
root     31160  3415  0 14:27 ?        00:00:00 sshd: myuser [priv]
myuser   31164 31160  0 14:27 ?        00:00:00 sshd: myuser@pts/1
myuser   31169 31164  0 14:27 pts/1    00:00:00 -bash

I'm not sure what lsof really is supposed to tell me, but it's supposed to be related, so here is its output:

Code:

Hi Mregine,

What does a simple ls -l show?

Regards

Only a minimal number of top-level directories...

Code:
~$ ls -l 
total 14
drwxr-xr-x  2 myuser group  3 Jul 21 05:28 Desktop
drwxr-xr-x  4 myuser group  4 Jun 18 19:33 Work
drwxr-xr-x 12 myuser group 12 Jul 21 05:41 local
drwxr-xr-x  2 myuser group  2 Mar  6 15:01 windows

windows is empty, Desktop contains only one 20-line text file with config stuff, local has some stuff I compiled and my svn repository (du says it's 34M of the total 72), and Work accounts for the rest. ls -lah reveals no large hidden files (nothing larger than 175K, .ICEauthority).

Hi Mregine,

Is the file systems an auto mounted file system, it could well be that the fs has been filled up on the sharing server.

The name "misc-home-1" suggests that you will not be the only user with access to this bit of disk, you may have to wait for the systems admin to have a look.

Regards

Dave

What's an "auto mounted file system"? And how would I know?

(I'm still busy googling, but I haven't found anything helpful for me as a user without admin rights)

Create an alias called "du."

Code:
alias du.='du -k | grep -v "/.*/" | sort -n'

Then using a combination of du.'s ... cd's ... & ls -la's you should be able to determine where and which file(s) are using the most disk space.

example: (cd /home/myuser)

Code:
ls -la (look for files that are large)
du. (this will show you the relative size of your sub-directories)
cd (to the largest sub-directory)

repeat until you find large file that you do not want and delete them.

According to what you posted, there is no reason to believe you are in cause in this disk full situation. The NFS server hosting your home directory and likely many other ones is simply full. You have been misled by questions asking about df and du discrepancy. Here, this discrepancy is expected as du is run on a subdirectory (hour homedir), not the whole file system which what df is reporting. There is not that much you can do outside waiting for an admin to fix the issue as you are likely missing the rights required to identify which other user(s) is/are using too much space.
