Thanks for the info. Some questions arise:

1. Is slurmd running on the node?

2. What’s the output of “slurmd -C” on the node?

3. Define State=UP in slurm.conf in stead of UNKNOWN

4. Why have you configured TmpDisk=0? It should be the size of the /tmp

I hope changing these slurm.conf parameters will help.
