Looking at lsblk on the two machines here. I noticed that I have a separate array for swap on one machine, but not in the other (it is just in a logical volume). I just realized that one advantage of the swap array is to provide an easy place to steal a few sectors in this "too small replacement drive" situation. -- Anthony Carrico
