So I had two 1.5TB drives formatted as one Raid 1 volume with about 1.3 tb of files on them.
I added two 3 TB drives, one at a time and rebuilt Volume 1 to the first one and then removed the remaining 1.5 and added the second 3.0 and rebuilt Volume 1. All went well.
I wasn't watching carefully when I formatted Volume 2 and formatted it as jbod (I wanted another raid 1 volume)
I had already moved the 1.5's to a 323 and set them as raid 1 and moved about 200 gig of data to them.
Considering what I have what is the best method to get the 325 and the two 3TB drives onto 1 volume?
