NOTE: There will be no change in behavior unless partition configuration 
  or node Features/Weight are altered using the scontrol command to differ 
  from the contents of the slurm.conf configuration file.

  Preserve current partition state information plus node Feature and Weight 
  state information after slurmctld receives a SIGHUP signal or is restarted 
  with the -R option. Recreate partition plus node information (except node
  State and Reason) from slurm.conf file after executing "scontrol reconfig" 
  or restarting slurmctld *without* the -R option. 

     OPERATION            ACTION
     slurmctld -R         Recover all job, node and partition state
     slurmctld            Recover job state, recreate node and partition state
     slurmctld -c         Recover no jobs, recreate node and partition state
     SIGHUP to slurmctld  Preserve all job, node and partition state
     scontrol reconfig    Preserve job state, recreate node and partition state

  Old logic preserved node Feature plus partition state after "slurmctld" or 
  "scontrol reconfig" rather than recreating it from slurm.conf. Node Weight 
  was formerly always recreated from slurm.conf.
