Or do you have to shrink the file system then the lv to have the space back? I'm going to back up anything that I need to be safe, but I'd like to avoid a total reinstall right now(that's for May). Thanks again. I think you've got me on track. One more quick one, on 9 you said "amount occupied + some" wouldn't it be minus some? Stuart answered at least as well as I could, but for the last, "occupied + some" is what I meant. By "occupied" I am talking about the amount of data that actually exists in your "/" volume. Then, since you need a little room to grow, add some to that value, so that you have a bit of free space in that volume. ( As well as Stuart's explanation, to leave room for errors. ) Brian
