What is taking up so much space on my disk, beside the filesystem?

I asked this on stackoverflow, but maybe here is a better place.

On my ubuntu 11.10, /dev/sda3 (150GB) is mounted on / and /dev/sda1 (80GB) is mounted on /home. My entire disk has 250GB and the system is reporting I am running out of disk space. Here is the output of df -h:

Filesystem            Size  Used Avail Use% Mounted on
/dev/sda3             149G  141G     0 100% /
udev                  3.9G  4.0K  3.9G   1% /dev
tmpfs                 1.6G  860K  1.6G   1% /run
none                  5.0M     0  5.0M   0% /run/lock
none                  3.9G  508K  3.9G   1% /run/shm
/dev/sda1              74G   15G   56G  21% /home

Ubuntu disk usage analyzer report the same thing. But this is weird because I believe I never used that much space on /. I also check every individual directory under / ( exclude /home ), and they don't use that much space:

8.8M    bin
4.0K    dev
0   initrd.img
0   initrd.img.old
828M    lib
15M lib32
4.0K    lib64
4.0K    media
0   proc
9.2M    sbin
0   sys
1.1G    var
108M    boot
18M etc
4.0K    mnt
40K root
4.0K    selinux
72K tmp
0   vmlinuz
0   vmlinuz.old
16K lost+found
133M    opt
1004K   run
4.0K    srv
5.9G    usr

Any one could give me some idea what is using up the space? Thanks in advance.

one thing to add is that I turned the ufw log to full, then I noticed some extreme large log files. But I deleted the log files and turned the ufw log to low again. not sure if that's the problem.

ls -sh does not report sizes as you'd expect. It does not look inside the directories, and just reports then at some fixed size (usually, 4,0k)

There are many tools to check what is taking space on your disk. I'd recommend gdmap. It will show you a self-explanatory map of your disk

To install:

sudo apt-get install gdmap

to run, use

sudo gdmap -f / , if you want to check the whole disk

sudo gdmap -f /some/folder, to check some specific folder

Instead of installing an additional tool on your computer, you can use the built-in and decent "Disk Usage" (baobab is its executable).
