Well, splitting and putting back together is not what I'm doing, although it
might look like that.

Although I currently have only 1 logical volume, and all my PV's are currently
a part of it, that's not necessarily how things will always be.  I
intentionally partitioned most of my disk into ~2GB chunks like this, so that
I can have a pool of 2GB PV's which I can throw at whichever LV needs it, and
thereby rid myself of future space constraint issues I've run into in the past
with traditional partitioning.

Yeah, that seems to be the general consensus.  Looks like LVM was until
recently either ignoring extended partitions or not reporting error messages
on them, which is why I only started to see this recently.
