You didn't restore the LV, you created a new one.  That clears the first
block, so you likely will need recovery efforts on your erstwhile 
filesystem.

What you *should* have done is restore the metadata to the point before
your errant command.  You can still do that (if it is still in the archive),
but the several K of zeros written to the start of the LV you created will
require recovery.
