ZFS RaidZ - Only One HDD Light Active

[Paul Kraus]

What does a `zpool iostat -v 10` show ?

What does an `iostat -x -w 10' show ?

If the above show disk activity on all drives then you probably have bad 
chassis wiring to the other drive LEDs.

While sorting out another problem, I had the cover off on my server and noticed that only a single HDD activity light is lighting up. Only disk #3, none of the other drives seem to be showing any activity. I've been scrubbing the zpool for a few hours now and didn't notice any other lights lighting up.
