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. )
