You can shrink a PV, but you will loose the extents that are stored in the space that you have truncated. I don't consider that resizing.
Changing the size of something is called resizing.
How would you distinguish between the resizing done by e.g. resize2fs and the one done by fdisk?
Unfortunately, pvmove can only move extends to other PVs but not to a different location in the same PV.
Not true. It isn't as straightforward; you have to know a map of the PEs and specify them to the pvmove command like (assuming the destination PEs are not in use):
pvmove /dev/sda2:1000-1100 /dev/sda2:100-200
Oh, I didn't know about that. It seems that this thread finally produced some useful information as well, thanks!
