Maybe someone else could take a look as well.  Some of the LVM metadata
files in the archive directory appear to be missing logical_volumes {}
sections.

I wonder if this could be fixed with a simple 

  vgcfgrestore -f /etc/lvm/backup/storage storage
  vgscan
  vgchange -ay storage

Also it looks like some of the older archived versions would be valid
as well.

  vgcfgrestore -l storage

Should give a list...
