I''m getting the following status from a ZFS mirror.

unknown# zpool status
  pool: mypool
 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 online'' or replace the device with
''zpool replace''.

I''ve made a scrub, but READ errors increase. Should I replace HW with
this level of errors? Pool has just been used for a zone install.
