I can't give you an authoritative answer, because I don't know UFS

available and may want to use it at some point getting EIO then.
Well, my ovservation from using "diskinfo -t -v" on my /dev/ad4
device and then on the /dev/mirror/gm0 device after the mirror create
shows a slightly smaller mediasize. Now, whether the UFS knows it is
smaller or not, I can't say, but the lower level of the OS is
reporting a smaller media size.
In any case, every time I partition a disk, fdisk always leaves a
bunch of sectors hanging off the end. I presume that's where gmirror
stores its data for whole-disk mirror... at least I'd hope!
