Description
Twice now when I've had an active drive fail and get replaced by a spare, the spare itself had too many bad sectors and the replace fails.
It would be much better to detect the spare is bad before it is needed to rebuild a degraded vdev. We need a method that spares are periodically written to in their entirety and verified.
Possibly as part of a pools scrub procedure or separate function.

We can probably borrow the logic for this form Nexenta. I wrote just such a verifier for them, and its in their open source tree, or at least it used to be.
