Thanks, but is it really necessary to copy the PE at all? It's broken,
and I don't care about that 8MB of data. Isn't it possible to just
reassign the LE that's mapped to the broken PE to a completely empty PE
at some other disk?

At the moment I'm a bit tempted to just set up a new VG, and migrate
data from the old VG file by file, disk by disk.
