>> 2. in a raidz do all the disks have to be the same size? Disks don't have to be the same size, but only as much space will be used on the larger disks will be used as is available on the smallest disk. In other words, there's no benefit to be gained from this approach.

E.g., can you do a 3-way raidz with 2 complete disks and > one slice (of equal size as the disks) on a 3rd, larger, disk? Sure. One could do this, but it's kind of a hack. I imagine you'd like to do something like match a disk of size N with another disk of size 2N and use RAID-Z to turn them into a single vdev. At that point it's probably a better idea to build a striped vdev and use ditto blocks to do your data redundancy by setting copies=2.
