Firstly, pvmove --abort abandons a pvmove cleanly.

Two ideas:
  Use dmsetup directly to hide the problematic PE.
e.g. dmsetup table vg1-lvol1 to display the table,
  Work out which sector(s) are the problem and replace them with
  an 'error' line


  Edit a (current) VG backup file to 'move' 1 extent elsewhere.
e.g. 1 segment containing the problematic extent turns into 3 segments
