<br>
One thing - do the nodes return to this state when you resume them with <br>
"scontrol update node=srvgridslurm[01-03] state=resume" ?<br>
<br>
If they do then what does your slurmctld logs say for the reason for this?<br>
<br>
You can bump up the log level on your slurmctld with (for instance <br>
"scontrol setdebug debug" for more info (we run ours at debug all the <br>
time anyway).<br>
<br>
All the best,<br>
Chris<br>
