root partition full

Can someone help me figure this out.
It states that it has no space left on the drive

#sudo df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 143G 141G 0 100% /
tmpfs 1012M 0 1012M 0% /lib/init/rw
varrun 1012M 116K 1012M 1% /var/run
varlock 1012M 0 1012M 0% /var/lock
udev 1012M 3.0M 1009M 1% /dev
tmpfs 1012M 12K 1012M 1% /dev/shm
lrm 1012M 2.0M 1010M 1% /lib/modules/2.6.27-11-generic/volatile
/dev/sdd1 111G 67G 39G 64% /home

did a du -sh on each of the directory

6.1M bin
31M boot
3.0M /dev
16M /etc
4.0K /initr
247M lib
16K lost+found
138M opt
7.7M root
7.3M sbin
2.9G usr
400M var

As you can see this does not total up to 141G
the home directory is mounted on a different drive

What about /tmp ?

Do this instead - might take a while ...

Code:

sudo du / -x --max-depth=1 | sort -nr | less

Also, have in mind that normal & modern linuxes take a 10% of your partitions just to prevent them from collapse. Think, transactional partitions need more space for doing operations, so completely full partitions are unusable. So, if it is "full", you still can load your own system (no rescue/live cd needed) and free some space.

Ah! du is not at all a good solution, because if your partition is divided in 4096bytes blocks, a file with just 1 byte will be seen as 1 byte file by du, but it will be filling an entire block, so 4096 bytes will be locked.

Edit: 'du' DOES count sizes by partition block size. See below.

What do you propose as the more suitable alternative?

'df' is the only one, I suppose. The only problem with 'df' is the percentage: 99,6% full will be seen as 100%, just it.
Just a trick: 'df' doesn't need root privileges to be run: it's ok to run it as a normal user (without 'sudo' or 'su').

I mean for displaying the disk usage of files/directories within the mounted filesystems.

du -sk / .[0-9A-Za-z]* | sort -n

Sorry to all. I correct myself: 'du' DOES count sizes by block size. It's ok to use it as a real disk usage tool. Only keep in mind that numbers shown by plain 'du' are in kB. So a file with just 1 byte will show a '4' in a 4kB block size partition. I'll now correct previous posts to prevent errors to others

Edit: syg00 first post is what probably you're looking for.
