  Paul, you are really helpful. But I got myself into more knots.
vgconvert said:
  lv_number -19205086645 too large
 ...
  Use pvcreate and vgcfgrestore to repair from archived metadata

But now vgdisplay, vgconvert, vgscan, pvscan  all give 'segmentation
fault' and the disk  claims to be uninitialised for the graphical lvm
client. 
    Do you think there is a way to recover this?
   Sorry,
