Hi Mahmood,

I think, the problem was:
the python script 
which is called by the command rocks sync slurm
did not restart slurmd on the Head-Node.

After the restart of slurmctld, slurmd on the Head-node had the old 
and the Head-Node was drained.

I will fix this for the next release

Best regards
