Description Matt Mix 2020-02-29 19:24:42 MST 
The plugstack.conf configuration on the controller node does not reflect in slurmd. The file, plugstack.conf, is also missing from the conf-cache directory.

I was able to fix the missing file by modifying this line to use plugstack_config instead of topology_config:

https://github.com/SchedMD/slurm/blob/03a30514ae587ef795c639a7f27c2da75ac40757/src/common/fetch_config.c#L350

Yet it still doesn't use plugins defined in the file. It does work if I copy the file in conf-cache to /etc/slurm/plugstack.conf. I think the issue is due to spank_stack_init using the configured PlugStackConfig path rather than the conf-cache location on slurmd configless nodes.

Thanks,
Matt Mix

Hi Matt -

In the future please submit patch suggestions under the 'C - Contributions' category; it'll get them processed much faster.

This, alongside a few other fixes for configless operation, are in 20.02.2 going forward.

Thank you for the fix.

- Tim
