An excellent point. BTW, does the system *ever* read from the log device during normal operation? Such as perhaps during a scrub? It really would be nice to detect failure of log devices in advance, that are claiming to write correctly, but which are really unreadable. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
