Run 'sinfo -R' to see if any of your nodes are out of the mix.
If so, resume them and see if things work.

Hi all, anyone have suggestions for debugging cloud nodes not
resuming? I've had this working before but I'm now using "configless"
mode so wondering if that's an issue.
If I login as SlurmUser and run the ResumeProgram manually, the
specified node(s) boot, and if I log into them `sinfo` works although
it only shows the "static" nodes, not the newly booted "cloud" nodes.
So that at least shows the program works, the image works, and new
nodes can contact the slurmctld.
However if I run a job which requires cloud nodes it immediately goes
Pending showing "Nodes required for job are DOWN, DRAINED or reserved
for jobs in higher priority partitions". Looking at SlurmctldLogFile
with SlurmdDebug=debug5 I don't see any attempt to boot the nodes at
all :-(.
I can post slurm.conf if anyone wants to look but I think the
important parameters are probably that I've got:
SlurmctldParameters=enable_configless,idle_on_node_suspend,cloud_dns,power_save_interval=10,power_save_min_interval=0
That look right?
thanks for any suggestions!
