The slurm-roll hosted on sourceforge is developed and supported by Werner Saar not by developers of Rocks and/or other Rocks application rolls (e.g. SDSC).

There is ample documentation on sourceforge[1] on how to configure your Rocks cluster to properly deploy the slurm-roll components and update your Slurm configuration.

There is also an active discussion group for the slurm-roll on sourceforge[2] where Werner supports users of the slurm-roll for Rocks.

While we don't use Werner's slurm-roll on our Rocks/Slurm based systems I have installed it on test system and can say that it works as expected/documented.

In the default configuration WCKeys were NOT enabled so this something that you must have added to your Slurm configuration.

If you don't need the WCKeys capability of Slurm perhaps you could simply disable it in your Slurm configuration.

Hope this helps,
