      there are two issue here:
      1- there is no indication the status of DONOR
      2- the label UP, isnt tell that it cant perform a WRITE cause is in donor mode

      for operational point of view we need AWAYS to mark the DONOR status, but also a better view status like 'Up/Donor/no_write_allow' would help a lot

      the right command " maxctrl alter monitor cluster_monitor available_when_donor true " make the swich status happend from UP to WRITE, still missing the donor status
