October 27, 20223 yr I found a few posts with similar titles but they weren't quite asking the same question (I think). I am using the clear-disk method to shrink the array and I have two parity drives. When I checked "Parity is Valid" and went to start the array I got the message, "Dual parity valid requires ALL disks in their original slots." The instructions say to click "Proceed," but I got cold feet since this message seems to be calling out dual parity specifically. I can wrap my head around the idea that zeroing the drives makes the first parity drive valid when they are removed, but I don't really understand the method the second parity drive uses well enough to know whether the same holds true for it. Can I proceed?
