A development server that's in use is not a production server. Those are visible to the world. I don't think it's unreasonable to go in, add a drive group, add these drives to the group, and have it rediscover them and present them to me. Why is that not a safe thing? Other than the rediscover the RAID, it's no different than shoving an ordinary drive into one of the hot swap bays and mounting it under /mnt. <snip> mark
