The easiest thing to do is probably to use some or all of the
available 4Gb as a new filesystem mounted under /usr. For instance,
/usr/local might be a good choice. You need to copy the current
contents of /usr/local onto the new partition, move the old /usr/local
aside somewhere and mount the new one in it's place:
Assuming the disk partition where you have space is /dev/da2s2
something like the following (in single user mode):
mount -a
fdisk -i da2 [ Mark slice 2 as belonging to FreeBSD ]
disklabel -e da2s2 [ Create a 4.2BSD partition /dev/da2s2e, say ]
newfs /dev/da2s2e
mkdir /usr/local.new
mount -t ufs /dev/da2s2e /usr/local.new
rsync -avx /usr/local/ /usr/local.new/
[ rsync(1) is only one way to copy the whole directory tree over.
Obviously, you need to install ports/net/rsync before dropping to
single user... Another alternative might be:
cd /usr/local ; tar -cf - . | ( cd /usr/local.new ; tar -xvpf - )
or there are similar methods using find+cpio, dump+restore etc.]
umount /usr/local.new
mv /usr/local /usr/local.old
mkdir /usr/local
mount -t ufs /dev/da2s2e /usr/local
diff -ur /usr/local.old /usr/local [ make sure everything copied OK etc. ]
vi /etc/fstab [ add /dev/da2s2e to standard mounts ]
reboot
Now, when the system comes back up multiuser you should have a
separate /usr/local partition containing the same files as the
original /usr/local directory. Once you're satisfied that everything
has gone according to plan you can delete /usr/local.old and make
merry in the extra space that becomes available.
Cheers,
Matthew
