 Well i have a similar problem and i HAVE type DERIVE an minimum set to

inicio=`date -d '2002-06-01' +"%s"`

  rrdtool create --start $inicio interface.rdd --step 60 \
  DS:in:DERIVE:600:0:U                               \
  DS:out:DERIVE:600:0:U                              \
  RRA:AVERAGE:0.5:1:600                              \
  RRA:AVERAGE:0.5:6:700                              \
  RRA:AVERAGE:0.5:24:775                             \
  RRA:AVERAGE:0.5:288:3725                           \
  RRA:MAX:0.5:1:1:600                                \
  RRA:MAX:0.5:6:700                                  \
  RRA:MAX:0.5:24:775                                 \
