Hey Slurm-users list, meanwhile I was able to find: [2026-03-23T12:58:16.105] debug: gres/gpu: init: loaded [2026-03-23T12:58:16.105] debug: gpu/generic: init: init: GPU Generic plugin loaded [2026-03-23T12:58:16.105] warning: Ignoring file-less GPU gpu:L4 from final GRES list [2026-03-23T12:58:16.105] debug: skipping GRES for NodeName=my_worker_node Name=gpu File=/dev/nv dia0 [2026-03-23T12:58:16.105] debug: skipping GRES for NodeName=my_worker_node Name=gpu File=/dev/nv dia1 [2026-03-23T12:58:16.105] debug: gres/gpu: init: loaded [2026-03-23T12:58:16.106] debug: skipping GRES for NodeName=my_worker_node Name=gpu File=/dev/nv dia0 [2026-03-23T12:58:16.106] debug: skipping GRES for NodeName=my_worker_node Name=gpu File=/dev/nv dia1 [2026-03-23T12:58:16.106] debug: gres/gpu: init: loaded so I am wondering whether that is the issue. I also noticed that after powering up the node without requesting a gpu (works), scheduling to the node by requesting a GPU is not an issue. Best, Xaver On 3/20/26 17:21, Xaver Stiensmeier wrote:
Hey Slurm-users list,
while our regular gpu nodes are working fine, our on demand gpu nodes have a weird issue. They power up, I can ssh onto them and execute nvidia-smi on them without issue, but they are marked invalid and slurmctld logs
_node_config_validate: gres/gpu: Count changed on node (0 != 2)
however, node show shows that the gpus are recognized and the gres.conf are stored on the worker nodes as expected and the node entries in the slurm.conf are fine, too:
# slurm.conf NodeName=my_worker_node SocketsPerBoard=16 CoresPerSocket=1 RealMemory=64075 MemSpecLimit=4000 State=CLOUD Gres=gpu:L4:2 # openstack
# gres.conf on my_worker_node ubuntu@my_node:~$ cat /etc/slurm/gres.conf # GRES CONFIG Name=gpu Type=L4 File=/dev/nvidia0 Name=gpu Type=L4 File=/dev/nvidia1
Thankful for any ideas and debugging ideas.
Best, Xaver
PS: By executing:
sudo scontrol update NodeName=$(bibiname 0) Gres= sudo scontrol reconfigure sudo scontrol update NodeName=$(bibiname 0) state=RESUME reason=None
the node can be resumed. However, this is not a real solution.
