	  1) size AGs so that they do not always start on the same part of a striped
	  disk; that is, AG size % Stripe Width is not 0.
	  With 4GB AGs we are always starting AGs on first disk in a stripe.
	  2) Fix an off-by-one error on rounding down an AG that is too small to be an AG
	  3) don't auto-grow the log to be larger than an AG
	  4) change the error philosophy for -d su=,sw= away from forcing the XFS 
	  stripe size to match the XLV stripe size and instead accept, with a warning,
	  the stripe unit & width supplied on the commandline.
