Base on what I have seen so far, when your thumper shows up it should have the following factory configuration, which is pretty close to your scenario above. c5t4 and c5t0 as boot disk mirror metadevices 1 pool with the following raidz groups: c0t0 c1t0 c4t0 c6t0 c7t0 c0t1 c1t1 c4t1 c5t1 c6t1 c7t1 c0t2 c1t2 c4t2 c5t2 c6t2 c7t2 c0t3 c1t3 c4t3 c5t3 c6t3 c7t3 c0t4 c1t4 c4t4 c6t4 c7t4 c0t5 c1t5 c4t5 c5t5 c6t5 c7t5 c0t6 c1t6 c4t6 c5t6 c6t6 c7t6 c0t7 c1t7 c4t7 c5t7 c6t7 c7t7 _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
