Let me give a different opinion on this approach.

It can be useful; one day you will want to have a "root for mandriva"
out of any LVM and you will simply kick one of the PV out of
the VG and turn the partition back to native.
I know there is pvresize, but I feel better when using pvmove alone
(which you will probably have to use in any case before pvresize).

More difficult: I want a 20 GB partition, and I'd like to have
it near the fastest part of the disk (the beginning). I just
kick sda6 out of the VG.

Having more than one PVs has no real disadvantage, so, why not?

(personally used to slice disks in 50GB or 100GB PVs)
