It's probably even easier than that if you have enough ports and bays for two more drives. What you'd have to do, roughly, is: 1. Add both of the new drives as additional mirrors of the z2 pool. Wait for resilver to complete. 2. Detach the original drives from z2. If autoexpand is set to on, z2 should now have 1.5TB. Otherwise export / import the pool. 3. Add the original drives to z2 as a mirror vdev. 4. Do a zfs send of all datasets from z3 to z2. 5. zpool destroy z3. 6. Add the drives from z3 to z2 a mirror vdev. Your z2 should now have about 2.75TB space. If you're so inclined, you could move some datasets from rpool to z2 to keep your rpool smaller. -B -- Brandon High : bh...@freaks.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
