You need to ensure that the deivce given isn't degraded. It's certainly
possible to boot with a mirrored root with one device degraded. If you choose
that device for grub-setup, you may fail to write to it or you may succeed,
but something else may prevent it from being accessible on boot.

Don't forget to check the state of the device also.
Can you be more specific? I notice a "state" integer variable associated
with the pool (none associated with the device), which has a zero-value in
my case (I assume this indicates no error).
What kind of errors can it indicate? Should we care even? Keep in mind
this routine is, given a pool that is known to be mounted, merely determining
its underlying devices, not asserting anything about its well-being.
