That's interesting. I do consider it resizing... It's not the function
of the pvresize command to move the LVs around so that it is possible
to downsize the PV. That's something that the admin must do.
My definition of resizing is shrinking without the need for temporary
additional storage. A partition can be resized by resizing the file
system and then shrinking the partition with fdisk. A logical volume can
be resized the same way. A physical volume can not be resized, you first
need to put the data (extents) somewhere else.
Yes, so it won't do exactly what you want in one command, so you
have
to do it a different way. I have in the past added a second PV,
In my case that doesn't work. I just created one PV for every harddisk,
I never had the need for additional PVs or partitions until now. Well,
my bad luck I guess.

I wasn't being particularly aggressive, but I do actually dislike
people saying (or abbreviating) "just for the record" when they are
incorrect or the facts are disputed. The only thing that goes in the
official record are the facts.
My intention was just to avoid a reply of the form "Then use an USB
stick instead". It's not that I am not able to work around the problems,
I just wanted to clarify that it can be quite a hassle.
Best,
