What about gmirror, though ? Does gmirror, or any of its associated binaries or libraries, have any equivalent to a 'zpool scrub' ? It seems like something you'd really want to do from time to time, not just wait for 'gmirror status' or smartmontools to start throwing errors ....UFS has no mechanism to verify data integrity.
