Well that is easy then, if they free space is directly after your 
current PV, you can just extend the partition in the partition table 
then use PV resize to grow (cleaner but tricker),.

The Second thing "Easily" way you could do is create a new partition 
using the free space, then create a PV on that, then extend the volume 
group to also use that partition. Simplez
