Kory, You can do exactly what you suggested to stripe the data across your two drives without losing data. Obviously, if your data is critical to you, then you should consider investing in two additional drives so you can mirror them them later. It's worth noting that once you go to a stripe you won't be able to remove that stripe later. BTW, you should send email to zfs-discuss at opensolaris.org if you need more assistance as there are more subscribers on that forum. This one devoted to the zfs code. Thanks, George
