[SOLVED]ZFS One or more devices has experienced an unrecoverable error

a ZFS pool was scrubbed. It had quite a history of kernel panics due to a faulty USB cable. ZFS "feels" that the devices were in error, which I don't believe to be true. How do I reset or reconfirm the status of the devices? If at all they cannot be faulty all of them at the same time, can they?

# zpool status -v
  pool: zdata
 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'.
