Here's my output of df -h:

[root@box root]# df -h
Filesystem            Size  Used Avail Use% Mounted on
                      1.8T  231G  1.5T  14% /
/dev/sda3              92M   27M   61M  31% /boot
tmpfs                 3.9G     0  3.9G   0% /dev/shm
/dev/sdc1             7.6G  6.3G  1.3G  83% /mnt/backup

I have a drive plugged in that I use as a backup which is aptly mounted at /mnt/backup. I've been getting errors that I can't copy files to this directory. So I tried to see what's using up the space, and therein lies the confusing part:

[root@box backup]# pwd; ls -a
.  ..

What's up with that‽ There are no files but 6.3 GB is being used?

Try checking the file system. – Dennis Feb 25 '13 at 14:05
Show the output of du -s /mnt/* or du -s /mnt/backup/*`. – ott-- Feb 25 '13 at 14:53
@ott : [root@box backup]# du -sh /mnt/* 4.0K /mnt/backup – Hut8 Feb 25 '13 at 15:17
Hmm. Could be the answer? – ott-- Feb 25 '13 at 15:41
