[slurm-users] srun --reboot option is not working

[Brian Andrus]

You may want to double check that the node is actually rebooting and 
that slurmd is set to start on boot.

ResumeTimeoutReached, in a nutshell, means slurmd isn't talking to 
slurmctld.
Are you able to log onto the node itself and see that it has rebooted?
If so, try doing something like 'sinfo' from the node and verify it is 
able to talk to slurmctld from the node and verify slurmd started 
successfully.
