- telinit 1
- umount all
- archive /usr onto tape
- delete the /usr logical volume, using smit or rmlv/rmfs/whatever
- create a new /usr logical volume of the correct size
- restore /usr from tape
- mount all
- telinit 2

A bit tedious, but it does save all the installation/update/patching/
configuring you've done in /usr.
