Now I'd >like to be more granular. 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.
