[slurm-users] 'srun hostname' hangs on the command line

[John Hearns]

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 run the
hostname command manually.
