Try to send him an email fdisk at util-linux.org :-)
Please be polite :-)

or maybe try

# partprobe /dev/sda

/sys/<something>/rescan. And I see in "dmesg" that kernel found new
size of the LUN. But when I type "fdisk /dev/sda" it still shows old
size. On /dev/sda1 sits LVM PV and I'd like to resize it instead of
adding one more PV to volume group.

I imagine sda1 is thee only partition on sda !

I know all LVM commands by hart and was not knowing pvresize !
What a crazy thing! A day it will be possible to move an entire
partition inside a disk, and doing this online !
Then LVM will become useless :-)
I thing a day a man will walk on the moon :-)
