You can start with two disks and create a stripe accross both disks. Keep in mind that if one fails you will loose all your data! Later on you can mirror disk one by *attaching* a disk to this vdev. But this way you still have no redundancy. If the second disk/vdev fails, you still loose all data. You need to *attach* a second disk to the second vdev also. That way you can loose a disk per mirrored vdev. So you will need 4 disks. regards
