OK ... well, in a 3 node configuration, there is no quorum drive, I am 
told. The quorum drive exists to break a tie between nodes, and you can't 
have a tie with 3 nodes ... and in the cluster we were working on, there 
is no Q: drive (in this particular case, it's an R: drive ...)

So ... presume I backup the quorum drive (if it exists). How do you 
restore the settings? Just restore the quorum drive and restart the 
cluster?
