Question re reducing a file system in FreeBSD 6.2

Hi,

I have a question re reducing a filesystem in FreeBSD 6.2 - I am new to 
FreeBSD - I am use to AIX

We have FreeBSD installed on a dell 1950 - I would like to reduce the size 
of /usr   in case I want to added the space to another file system.
We currently have all our space allocated as follows.

Here is the set-up

$ df -h
Filesystem       Size    Used   Avail Capacity  Mounted on
/dev/mfid0s1a    1.9G     59M    1.7G     3%    /
devfs            1.0K    1.0K      0B   100%    /dev
/dev/mfid0s1d    1.9G     14K    1.8G     0%    /tmp
/dev/mfid0s1f     58G    3.2G     50G     6%    /usr
/dev/mfid0s1e    1.9G     58M    1.7G     3%    /var
$ mount
/dev/mfid0s1a on / (ufs, local)
devfs on /dev (devfs, local)
/dev/mfid0s1d on /tmp (ufs, local, soft-updates)
/dev/mfid0s1f on /usr (ufs, local, soft-updates)
/dev/mfid0s1e on /var (ufs, local, soft-updates)

In AIX I can reduce the filesystem on the fly - however I don't think I 
can do that with FreeBSD from what I have seen and I am not sure how this
would be done consdering it is /usr I would like to reduce.
I am currently looking at google to see what I can find.

Any Suggestions you have would be helpful.

Thank you &
Regards
Irene
