Thanks, but it actually seems to be the same.  It accepts both.  I'm not
quite sure what the difference is.  But stricly speaking
"/dev/phantom-vg1/root" is the correct format:

  phantom-vg1 - the volume group which contains the logical volumes
  root        - the logical volume I'm tried to resize
