please help searching for big files on Centos 4.3

[bossadvisor]

Hello, all.

I am trying to determine which files take up the space on my Centos 4.3 server.
So far, I can't account for them using these methods.
I am stumped. Please advise.

1.
/]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 247G 216G 19G 93% /

2. I searched / for any file equal bigger than 5000K. That didn't account for 216 GBs reported being used on this server.
find / -type f -size +5000k -exec ls -lh {} \; | awk '{ print $9 ": " $5 }'

3. du / showed only 122 G
[]# du / -sh
122G /

4.
[/]# du /bin /dev/ /home/ lib/ /media/ /sbin/ /srv/ /tmp/ /var/ /boot/ /etc/ /initrd/ /lost+found/ /misc/ /opt/ /root/ /selinux/ /sys/ /usr/ -sh
5.3M /bin
152K /dev/
108K /home/
196M lib/
12K /media/
15M /sbin/
8.0K /srv/
3.9M /tmp/
5.7G /var/
17M /boot/
54M /etc/
8.0K /initrd/
16K /lost+found/
8.0K /misc/
18G /opt/
33M /root/
8.0K /selinux/
0 /sys/
2.1G /usr/

What does

ls / -al

report? have you got hidden folders like a trash folder?

Sorry. This suggestion did not help.
Nothing in .Trash
