Because my primary server went down today, I have a couple of servers
that have 'stale NFS mounts' which I can't unmount...

# umount /home/storage/users
umount: /home/storage/users: device is busy
umount: /home/storage/users: device is busy

short of restarting...is there a trick that I can do to umount/remount?
