Disk Full issue

["Rob Brenart (TT)" <Rob.Brenart@tradingtechnologies.com>]

I came in this Monday morning to find some problems on my debian server
because the disk is full.

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/cciss/c0d0p1       256149    256149         0 100% /

I can't seem to think of anything unnecessary that may be eating up the
space, perhaps I just made it way too small?

Can anyone think of a common offender I should be tracking down, or is
there a way to increase this partition without losing all my data?
