That's not true. You can shrink the PV with pvresize and then create
any desired partitions in the resulting space. Or did you mean
something different?
When I created 14 partitions using a DOS partition label
(3 primaries, plus extended containing 10 logical partitions)
and gave 6 of the partitions to an LVM setup,
then I could not remove one of the partitions from the clutches
of the LVM, and use the removed partition for some other purpose
(keeping the rest of the LVM going), unless I removed all the LVM
from that drive.
