I've had my 10x500 ZFS+ running for probably 6 months now and had thought it 
was scrubbing occasionally (wrong) so I started a scrub this morning, its 
almost done now and I got this:

errors: No known data errors
# zpool status
  pool: pile
 state: ONLINE
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'.
   see: http://www.sun.com/msg/ZFS-8000-9P
 scrub: scrub in progress, 97.93% done, 0h5m to go
config:

So it says its a minor error but still one to be concerned about, I thought 
resilvering takes care of checksum errors, does it not?  Should I be running to 
buy 3 new 500GB drives?

Thanks,
Sam
