Curious:

[r...@nas01 ~]# zpool status -x
  pool: tank
 state: DEGRADED
status: One or more devices has experienced an unrecoverable error.  An
        attempt was made to correct the error.  Applications are unaffected.
action: Determine if the device needs to be replaced, and clear the errors
        using 'zpool clear' or replace the device with 'zpool replace'.

Why has it been reported as bad (for probably 2 months now, I haven't
got around to figuring out which disk in the case it is etc.) but the
iostat isn't showing me any errors.

Note: I do a weekly scrub too. Not sure if that matters or helps reset
the device.
