I want to increase the size of the vdev, not just the zpool. I want to make a 3-drive array into a 4-drive array by adding a single drive while still having one parity stripe across all data. Adding more vdevs to a zpool isn't quite the same thing as online capacity expansion. It's not something most businesses would do, which is why the feature never made it into ZFS, but consumers are cheap and mdadm supported it. From what I've read, btrfs supports it, too.
