Recreating the vg overwrites the human-readable data at the beginning of
the device.  You claim that it is "still there" and is the "same
information".  But this cannot be true because originally that
information had your LV data, and now (apparently) it does not.  Do you
see your LVs when looking at the vg metadata with an editor??   What do
you mean by "displays the same information"?  Does lvs list your LVs?
