Yeah, I did it the wrong way the first time and wound up with a raid-6 array that expected one more drive than I had. It would be a lot easier if I could have specified the target number of destination stripes and then also specified the number of parity stripes. I needed to reduce the added space back out, so that it could be added as a parity device instead of another data-device.
