              So, should I rewrite the beginning of the device with
                the dd command?
              

              What then?
              

              Thanks a lot for all your help!
              

    You could try the dd, if it has a good chance of restoring the
    device to before the pvcreate.  I don't know offhand how much of a
    PV pvcreate overwrites.  Hopefully, an LVM guru can chime in. 
    Before doing pvcreate, things like vg_scan -v should give a clue as
    to whether knoppix is even looking at md127.  You might need to
    tweak the device filter in lvm.conf for knoppix.
