There's no reallocation process that I'm aware of. Obviously adding a single column to a pretty full volume prevents you from doing the most optimal (full-stripe) writes. But since the existing parity disk covers the new column, you do have full availability of the new space. That's a different story with raidz. Hopefully you don't wait until the raid group is full before adding disks, and the blocks sort themselves out over time. -- Darren Dunham [EMAIL PROTECTED] Senior Technical Consultant TAOS http://www.taos.com/ Got some Dr Pepper?
