Ah, so this would be why say a super-capacitor backed SSD can be very helpful, as it will have some backup power present. Luckily, my use case is not a high-availability server, but a NAS in my basement. I've got it attached to a UPS with very conservative shut-down timing. Or are there other host failures aside from power a ZIL would be vulnerable too (system hard-locks?)? _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
