Don, Can you send the entire 'zpool status' output? I wanted to see your pool configuration. Also run the mdb command in a loop (at least 5 tiimes) so we can see if spa_last_io is changing. I'm surprised you're not finding the symbol for 'spa_scrub_inflight' too. Can you check that you didn't mistype this?
