Which is why I wrote (in the part you failed to quote):

-------
Use fdisk to make it larger, reboot, then run pvresize
on the PV, then run lvresize on the LV, then run resize2fs on the
filesystem on the LV.

The man page for pvresize says that's what it does. I don't even
have pvextend on my system here. Did you mean "vgextend"? That's
on a different layer of the LVM system, and is used for the other
(more complicated) approach of making a new PV.

If you have a spare disk lying around, you can recreate this
approach on that disk and see how it works. A keychain drive
should work fine.

The OP has a recent backup. Right?
