Ok, so the only time you *need* /etc/lvm/* is if you have to recover from bad
metadata.  Every PV in your VG has a complete copy of the metadata for that
VG, so you have multiple copies of the layout - if you have one of these, you
can recover your LVM setup.

Seeing the output of 'vgscan -vvv' and 'vgchange -ay -vvv' would be helpful -
maybe you could toss it up on pastebin.com?
