[slurm-users] Re: salloc not starting shell despite LaunchParameters=use_interactive_step

Thanks Jason for the hint. Looks like, the parameter was kept in slurm.conf from previous SLURM versions at our site.  Works also without setting InteractiveStepOptions in slurm.conf.

Best Regards, Carsten

Ours works fine, however, without the InteractiveStepOptions parameter.

Hi Loris,

we use SLURM 23.02.7 (Production) and 23.11.1 (Testsystem). Our
config
contains a second parameter InteractiveStepOptions in slurm.conf:

InteractiveStepOptions="--interactive --preserve-env --pty $SHELL -l"
LaunchParameters=enable_nss_slurm,use_interactive_step

That works fine for us:

[k202068@levantetest ~]$ salloc -N1 -A k20200 -p compute
salloc: Pending job allocation 857
salloc: job 857 queued and waiting for resources
salloc: job 857 has been allocated resources
salloc: Granted job allocation 857
salloc: Waiting for resource configuration
salloc: Nodes lt10000 are ready for job
[k202068@lt10000 ~]$

Best Regards,
Carsten
