ZFS doesn't work that way: it works on pools of storage. Disks are added to the pool. Filesystems (or datasets) are carved out of a pool, not out of physical disks directly. There are vdevs on top of physical disks. That's like people who are stuck back in the '80's because of ext3 arguing that ZFS is crap because it doesn't come with fsck or "some sort of repair tool" -- they just can't wrap their head around the ZFS concepts.
