Log devices are generally write-only. They are only read during boot, after an ungraceful crash. It is extremely difficult to get a significant number of GB used on the log device, because they are flushed out to primary storage so frequently. They are not read when you do a scrub. For all these reasons, it will be extremely difficult for you to experimentally produce a checksum error on a log device. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
