I ran onto a similar problem when trying to create a LV where the ramdisk PV
came FIRST. It wouldn't do it even though I ordered it first in the list. So
what I had to do was create a VG out of the first PV alone, and the LV on
it, and then keep adding PV to VG and extend the LV. That resulted in a
If the composite VG already exists, the only technique I know is to search
or even write characteristic data patterns in the LV and also in all the
PVs, thus determining offsets :-(
