It'll be fine. ZFS opens by path, but then checks both the devid and the on-disk vdev label, which is dispositive when the others disagree. > 2) if i create a raidz2 on 3 HDs, do i have any resilience?

A three-way mirror would give you better performance (because there's no parity to generate), but from a resilience standpoint they're equivalent.
