I would have dedicated only 2 disks out of 16 then to a single large raidz2 instead of two 8 disk raidz2's (meaning 4 disks went to parity) I was still operating under the impression that vdevs larger than 7-8 disks typically make baby Jesus nervous. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
