Perfect. That must have been then, since my script (like the example one) did not have the execution permission on. > I'm curious: What kind of disruption did it cause for your production > jobs? All jobs failed and went in pending/held with "launch failed requeued held" status, all nodes where the jobs were scheduled went draining. The logs only said "error: validate_node_specs: Prolog or job env setup failure on node xxxx, draining the node". I guess if they said "-bash: /path/to/prolog: Permission denied" I would have caught the problem myself. In hindsight it is obvious, but I don't think even the documentation mentions that, does it? After all you can execute a file with a non-executable with with "sh filename", so I made the incorrect assumption that slurm would have invoked the prolog that way. Thanks!
