Any indication that the disk turned bad from before ?

Looks like it either did and your single copy of the LVM1 metadata
went south
-or-
the metadata got corrupted somehow differently.

LVM1 didn't have UUIDs on LVs, that's why.
Can you access the VG from the rescue disk and access your data alright ?

If the disk's intact, and you better prove that by running access tests
on /dev/sda from your rescue disk, you have to restore the metadata from
backup using pvcreate+vgcfgrestore. See man vgcfgrestore for details.
