device 8:2 is /dev/sda2. Some one is trying to use /dev/sda2 with
incorrect values (start sector or length). This looks odd and this
happens only when you try 'pvmove' on the USB disk. What does the
pvdisplay on /dev/sda2 report its size (PV Size and is that accurate).
It maybe incorrect....

Thanks, Malahal.
