A backup of LVM metadata is stored in /etc/lvm (or where configured).
Metadata is also stored on PVs.  Your second drive was probably
a second VG (your details are rather vague), hence there was no PV
to override the lvm backup.

There was a version conflict between the /etc/lvm backup and the PV version
of VolGroup00, and it reverted to the PV version.
