you probably hadn't lost anything.  one approach that usually
works is to:

	vgexport vg0;
	vgimport vg0 /first/disk /second/disk;

likely to get you back to where you were before the vgextend.

if vgimport doesn't like them anymore you can create a new lv,
vgextend it to the two devices and create new vg's w/ the same
allocations as the old ones (simple enough if they havn't been
extended too many times).
