Technique 1, if you have a free hard drive:
/dev/hda1 is /, which is filling up
/dev/hda2 is unused.
/foo is some large directory (like /usr or /usr/local/src/ or /home

mount /dev/hda2 /mnt
cp -a /foo /mnt
(spot check /mnt if you're naturally paranoid like me)
(take a shot of something strong)
rm -rf /foo/*           #Leave foo directory there but not its contents
umount /mnt
mount /dev/hda2 /foo
edit /etc/fstab to make the mount happen at boot


Technique 2, if you have a hard drive in use with free space:
/dev/hda1 is /, which is filling up
/dev/hda2 is /bar, which is in use but has space.
/foo is some large directory (like /usr or /usr/local/src/ or /home             

mkdir /bar/foo
cp -a /foo /bar/foo
(spot check /bar/foo if you're naturally paranoid like me)
(take a shot of something strong)
rm -rf /foo             #remove /foo and the horse it rode in on
ln -s /bar/foo /foo     #links across filesystems must be symbolic

Good luck.
