Remember thta LVM doesn't effect the data on your disk, just
the LVM headers. If you remember the approx. sizes of things
you may be able to bring the LV back on line long enough to
back it up, blow off LVM, re-create the thing from scratcn,
run the VG backups and restore the original data.

All you can do it play around with it until the volume mounts.
