creating multiple PV on the same disk makes no sense.
if you were to do this you could well do without LVM and avoid the
hassle.

PV = Physical Volume = LVM idea of a single DISK
VG = Volume Group = a set of PV
LV = Logical Volume = where you put your data

i believe your problem is you created a giant LV, not a giant PV.

in this case you could resize the filesystem that is inside that LV
then lvresize the LV and create more LVs in the remaining space.
