The first hit on this search is a demo of ZFS detecting corruption of one of the mirror pair using checksums, very cool: http://www.opensolaris.org/os/community/zfs/demos/selfheal/;jsessionid=52508 D464883F194061E341F58F4E7E1 The bad drive is pointed out directly using the checksum and the data integrity is preserved. - Luke
