  Ahh!

raneb:/etc/lvm/archive# pvcreate --uuid v3HXpi-d5QN-OGiW-VFBG-TNIY-qTun-bFhlVd  --restorefile vg1_00026.vg /dev/hdb1
  Warning: Volume group vg1 is not consistent
  Physical volume "/dev/hdb1" successfully created

  BTW, I never understood if I should use disks or
  partitions is lvms.

  I presume I have to restore the lv somehow. But this
  has got me a step foward.

  Big thank and cheers,
