Yes, the autoexpand property (or whatever it's called). Although I'm not sure if it would help me in this case (because my requirements require that I keep the OS confined to 160G and partition the rest for other uses...) Another big benefit of ZFS mirror over hardware mirror is that when you scrub ... it will actually scrub both disks. If you scrub a hardware mirror, there's no telling *what* you're scrubbing. A block from the first one, a block from the 2nd one, a whole swath of blocks from the first one, alternating with just an occasional small chunk from the second one ... Maybe you're only hitting one disk the whole time, for all you know. The one thing you can safely assume if scrubbing a hardware mirror is that you're only scrubbing half of your data.
