Thanks again Bruce!  Storage Groups is my favorite new feature and
haven't looked back since.  Just trying to extend it a littler more
now :)

Right now I need to go back in and delete the storage groups I created
on the slave because they're identical (same mount point) as the
master.  So, they're duplicated so to speak.
