[CentOS] Resizing a PV that belongs within a Volume Group?

I was wondering if there was a way to extend (ie: grow) a PV that is part of
a Volume Group? I currently have a partition on my HD that is being used as
a PV for my Volume Group, but would like to make it larger. I have the
space on my drive to extend my partition, but using standard tools (ex:
gparted, Partition Magic, etc) would likely end up corrupting the data on in
the Logical Volumes that are housed within the VG.
I realize that I could just create a new partition on my HD and just add it
to my Volume Group and extend my Volume Group, however, given that it would
be two contiguous partitions on the HD, I was just wondering if there was a
way of resizing the original partition within the VG without causing any
I tried looking at tools like pvresize but I can't seem to understand the
right arguments to use it as whatever I try never seems to resize the
original partition itself. I also looked at system-config-lvm GUI tool, but
that doesn't seem to allow me to make the PV any larger.
Does anyone have any suggestions?
