I have an EX8350 in Raid 6 with 6 1TB drives originally. Over the years I have replaced the 1TB with 2TB drives and now have all 6 as 2TB drives. This leaves the array with 4TB of space as all drives are used as 1TB with 1TB free per drive.
How do I expand the array to now make use of all the drives 1TB free space? Included is a screen view of the WebPAM logical drive view.
