growfs on /

[Jeff LaMarche]

Hey all...

Have FreeBSD 4.8-STABLE, and I've run out of space on the slice /

I really want to avoid having to backup and reformat, or doing anything 
that's super-time-intensive - from reading various posts and blogs 
related to FreeBSD, it appears to me that I can resolve my issue by 
using growfs - the next slice after / is /tmp which has plenty of room 
free, and can afford to be reduced by a little. It doesn't seem to be 
affecting system use except that I can't add new users.

Here's what I look like now:

Filesystem  1K-blocks    Used    Avail Capacity  Mounted on
/dev/ad0s1a    128990  127682    -9010   108%    /
/dev/ad0s1f    257998    1254   236106     1%    /tmp
/dev/ad0s1g  18359694 4955608 11935312    29%    /usr
/dev/ad0s1e    257998    8400   228960     4%    /var
procfs              4       4        0   100%    /proc

I understand the process in general, but am a little afraid of hosing 
the box in the process; most of the stuff I've seen assumes a greater 
familiarity with tools like disklabel than I have. Does anyone know of 
a step-by-step tutorial or article on doing this? If not, would anyone 
be so kind as to give me a high-level breakdown?

Alternatively, if anyone knows how I can free up some space in / 
perhaps by moving something to another slice, I'd be open to that 
possibility.

Thanks in advance
