/proc is not in the root directory but a file system of its own. It does not take any disk space.

It's odd that /proc takes any disk space at all.

Anyway, your best choice would be to check the /var/log directory and archive and move old log files from there and also check the /root directory to see if there are any files taking a lot of disk space there.

Rotating the log files (with logrotate) would be a great idea for the future, if it is not already done.

/root is probably full because of pacct. perhaps you should change its configuration, it logs too much.

maota_u,

Did you tried to list out the files/directories which is consuming more space...chances are there wtmp will fillup the filesystem

List out the files that are having more that 100MB and decide upon the action

find / -xdev -type f -size +100000000c -exec ls -lh {} \;

Alternatively, to list the 20 largest directories in the root file system:

Code:
du -dok / | sort -rn | head -20
