It appears that sometime during the 33 and 34 files in archive/ the
UUID's on your PV's changed.

Do you see the above errors for storage_00034.vg?

What about for vgcfgrestore -l -f /etc/lvm/backup/storage storage ?

I'm not sure which one of these backup files I'd use to restore to.
You can also re-run pvcreate with the --uuid and --restorefile argument
if you want to recreate a "lost" uuid...

Still wondering how in the world this happened :)
