One example is that in a transparent vs hardcoded gmirror, the -1 would have to apply to both to allow "gmirror configure" to continue to work without accidentally destroying something. While we're on the topic of desired gmirror changes I'd like an easier method to "right-size" a mirror so that mirroring similar sized hard drives from different manufacturers doesn't create an Uff Da when the number of bytes isn't consistent. You can do this with gnop, but that requires extra steps. -- Adam Vande More
