(b) In my posts, I swapped slab for record. I really should have

(c) It is possible for constituent drives in a RaidZ to be issued
concurrent requests for portions

Slabs don't matter. So the rest of this argument is moot.
Tell it to Erik. He might want to know. Or maybe he knows better than you.

How long does it take to resilver a disk in that pool? And how long
