I luckily set it up on a development system so no big loss. But what ends up happening is that I tried to stripe my "e" slice which housed my /usr filesystem. Needless to say this is gone since you have to do a newfs once you configure the ccd. So my question now is this. What do I do about the /usr filesystem short of restoring from tape? Also how does one go about setting up ccd so that you can stripe/mirror existing information, since it seems anything that is on the involved slice gets wiped away. It is a neat product but it would be great if you could use it during installation or after install but not wipe out your old info. Any help anyone might have in this regard would be greatly appreciated. Eli
