Technically, raidz describes a vdev in a pool, not a pool itself. So yes, you can add another raidz to the pool. New data is striped across both components, but weighted to the empty one to try to balance things out a bit over time. No relayout occurs. > Also, is it possible to explicitly request a relayout; for example can > I convert a raidz1 pool to a raidz2 pool? Not today. My assumption is that other items (like zpool shrink/evacuation) are being targeted as a higher priority. -- Darren Dunham [EMAIL PROTECTED] Senior Technical Consultant TAOS http://www.taos.com/ Got some Dr Pepper?
