Yeah, it occured to me that this was probably the best opportunity I had
to increase the PE-size. So I set it to 32MB, giving me a maximum
LV-size of 2TB.
BTW: What are the effects of choosing a large PE-size? Apart from
getting larger LV's, of course? Does it effect performance or memory
usage at all?
