[CentOS] disk space issues...any help is greatly appreciated

Hi all,

Please pardon my newbie-ness on this issue....I've a / partition which 
is full (quite suddenly, actually) and I'm not sure how to fix this.

I've searched for uneeded logs, etc in /var/log and /tmp to no avail. 
The system is CentOS 5.2 and is not connected to the internet, serves as 
a local LAN server running stock stuff...sendmail, dovecot, 
apache..nothing strange or special going on.

I have additional HDDs available if growing the partition is in order 
(would appreciate pointers to that, if applicable), but I'm really 
stumped as to where the space is being eaten up.

Thanks in advance,

My layout is:
