I'm running FreeNAS-8.0-RC2-amd64 and currently have one volume. This volume consists of 3 2TB disks in a Raid-Z format. I would like to expand this volume (not add a new one) and would like to know how to go about doing that. I've done some Googling but as I'm new to FreeNAS it still left me pretty confused. I have one new 3TB disk that I'd like to use to expand the volume, is this possible? Or would I need to add 2 3TB disks to expand the volume? If somebody could layout what options I have in terms of expanding my current volume or even point me to some resources I can go over that would be greatly appreciated. Thanks in advance for any help!
