Hi
I'm running a cluster in a cloud provider and have run up against an odd
problem with power save. I've got several hundred nodes that Slurm won't
power up even though they appear idle and in the powered-down state. I
suspect that they are in a "not-so-idle" state: `scontrol` for all of the
no
ronan, you would test open ports using 'nmap'

Disabling the firewall service on the centos client allows the ‘srun hostname’
command to run.

Hi Carlos, Is there a way to test that? Are there certain ports that need to be
open? Thanks.

The communication from the compute nodes to the login nodes may be block by the
firewall. That will prevent srun from running properly

Ronan, as far as I can see this means that you cannot launch a job.
What state are the compute nodes in when you run sinfo?

Yes, srun just hangs. Commands like sinfo and squeue run fine.

Ronan, sorry to ask but this is a bit unclear.
Are you unable to launch ANY sessions with srun?
In which case you need to look at the logs to see why the job is not being
scheduled.
Is it only the hostname command which fails?
I would guess very much you have already run an ssh into a node and r
Yes I do.
