Red Hat :: Cannot Extend PV (LVM) After Resizing Partition

I know there are probably alot of threads about lvm however they aren't addressing my problem. I want to extend the PEs available in a VG. This VG already has LVs and those are active and mounted. From what I read from the manpages of pvresize this should be perfectly possible.
Code:
pvresize resizes PhysicalVolume which may already be in a volume group and have active logical volumes allocated on it.

I did the following steps and wonder if anyone has the same issue. THe machine where I am talking about is an ESX VM.
1. Resized the vmdk in ESX (+1G)
2. Let the kernel reread the device geometry: echo 1 > /sys/block/sdc/device/rescan
3. fdisk shows me the new size... so far so good
4. I resize the partition using fdisk (remove, recreate) and gave it the 8e type (lvm)
5. wrote config to disk
6. executed partprobe
7. pvresize /dev/sdc

Here it goes wrong! Pvresize says in the verbose output it sees the same size however at the end it says the pv has been resized. I have seen when I put volumes "offline" using vgchange -a n vg on a test machine, and then try pvresize it seems to work ok. This is against what is in the manual as it says pvresize should work on online mounted volumes.
