Easy way -- you don't have to move the entire partition, go to
single-user, get people to log off, etc.  Just pick some big, read-only
/usr dirs (e.g. /usr/doc, /usr/share, whatever) and do:

  cd /usr
  tar cf - share doc | ( cd /mnt ; tar xvfp - )

Then

  mv /usr/share /usr/share.old ; mv /usr/doc /usr/doc.old
  ln -s /mnt/{share,doc} /usr

And hey presto.  You can then remove /usr/share.old and doc.old at your
leisure,

--j.
