That is what your first choice should be.
Us du(1) to find out which directories are taking up the space.
cd /
du -sk * will give you a useful list.
It may be possible to move one or more of them to another slice
and make a soft link to it. But, most of the things in root
have to be there instead of somewhere else. You already have
the biggies somewhere else (/tmp, /usr, /var). Some of the
remaining directories may have extra junk left over from some
stuff that could well be deleted. A frequent culprit is home
directories for root accounts. If you are doing a bunch of
development, they can accumulate a lot of junk.
I wouldn't even consider growfs until after cleaning stuff up and
would not be confidant of using it on root anyway.
