Or just fdisk the thing, expand the last partition and reboot.  No
need to make things more complex than necessary.

?  Why not?  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.  Nothing to it.  If there's a total power
failure while pvresize is running, and you don't have a UPS, then
you're probably completely boned.  But that's always a risk.
