Well if pvcreate was run, and that is all, perhaps looking at the lvm
backup data in /etc can tell what the UUID used to be and pvcreate might
allow you to tell it what uuid you want used on that device. Then lvm
should recognize it again. pvcreate doesn't overwrite the data area of
a pv, just the block containing the size and uuid and such (and the size
shouldn't have changed). Unless I am missing something in my
understanding of LVM that is. If it was not previously an lvm device,
then year whatever was there is not hurt badly.
