If the number of available blocks on the 1TB disk is 2x the 500 GB disks, then you could make 2 partitions (slices) on the 1TB disk and mirror to each of the other disks. If the sizes are close but slightly smaller on the sliced 1TB drive, then you might need to be on a later build to attach the mirror. -- richard ZFS storage and performance consulting at http://www.RichardElling.com ZFS training on deduplication, NexentaStor, and NAS performance http://nexenta-atlanta.eventbrite.com (March 16-18, 2010) _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
