It would probably be better to iSCSI export the "raw" disks on the SAN boxes to the NAS Head. Let the NAS head do raidz2. That will make it easier to move disks between computers if you have to. Then you will have a redundant zfs pool on the NAS head without loosing any disk space. You could do 3 way raidz so that you can loose any SAN box. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
