Dear Slurm-user list,
Sadly, my question got no answers. If the question is unclear and you have ideas how I can improve it, please let me know. We will soon try to update Slurm to see if the unwanted behavior disappears with that.
Best regards, Xaver Stiensmeier

Dear Slurm-user list,
when a job fails because the node startup fails (cloud scheduling), the job should be re-queued:
Resume Timeout Maximum time permitted (in seconds) between when a node resume request is issued and when the node is actually available for use. Nodes which fail to respond in this time frame will be marked DOWN and the jobs scheduled on the node requeued.however, instead of requeuing the job, it is killed.

Our ResumeProgram does not change the state of the underlying workers, I think we should set the nodes to DOWN explicitly if the startup fails given:
*ResumeProgram* is unable to restore a node to service with a responding slurmd and an updated BootTime, it should set the node state to DOWN, which will result in a requeue of any job associated with the node - this will happen automatically if the node doesn't register within ResumeTimeoutbut in any case as we can see in the log the job should be requeued based on it reaching the ResumeTimeout alone. I am unsure why that is not happening. The power down request is sent by the ResumeFailProgram. We have SlurmctldParameters=idle_on_node_suspend activated, but that shouldn't affect Resume, I guess.
My Slurm version is slurm 23.11.5
Best regards, Xaver
