Mirrors are made with vdevs (LUs or disks), not pools. However, the vdev attached to a mirror must be the same size (or nearly so) as the original. If the original vdevs are 4TB, then a migration to a pool made with 1TB vdevs cannot be done by replacing vdevs (mirror method). -- richard ZFS storage and performance consulting at http://www.RichardElling.com ZFS training on deduplication, NexentaStor, and NAS performance Las Vegas, April 29-30, 2010 http://nexenta-vegas.eventbrite.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
