As Neil outlined, this isn't possible while preserving current ZIL performance. There is no way to distinguish the "last" ZIL block without incurring additional writes for every block. If it's even possible to implement this "paranoid ZIL" tunable, are you willing to take a 2-5x performance hit to be able to detect this failure mode? - Eric -- Eric Schrock, Fishworks http://blogs.sun.com/eschrock _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
