How does one do that? Is it as simple as using "attach" instead of "add" when creating the new vdev? For example: zpool create mypool raidz2 disk0 disk1 disk2 disk3 disk4 disk5 disk6 zpool attach mypool raidz2 disk7 disk8 disk9 disk10 disk11 disk12 disk13 Would it work for adding a third raidz2 vdev? -- Freddie Cash fjwc...@gmail.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
