I have removed the drive for the moment, and am running a backup. Just

Description : The number of I/O errors associated with a ZFS device
exceeded
                     acceptable levels.  Refer to
              http://illumos.org/msg/ZFS-8000-FD for more information.

attempt
                     will be made to activate a hot spare if
available. 

Impact      : Fault tolerance of the pool may be compromised.

Action      : Run 'zpool status -x' and replace the bad device.
