What I am curious about: where zfs checksum failures the only symptom of the bad disks or where there SMART failures as well?
In our ZFS JBOD setup with 90HDDs we scrub regularly and never find checksum errors. Instead, we might get a few recoverable read errors, but more likely, no SMART warnings, just sudden drive failure disappearing from the bus.
