Question about resizing raid groups.  Can one change the number of disks in a raid group on the fly in a netapp filer?  I currently have an aggregate with a single raid groups and I would like to add another shelf.  So as to reduce the amount of storage I lose can I change the size of the raid group and grow the underlying raid for the aggregate or do I have to start a new raid group?
