Hi all,
Fortunately I solved this problem by changing Slurm version from 22.05.9 to
23.11.10.
With Slurm 23.11.10, after stopping the primary slurmctld and
slurmdbd, when I submit a job with sbatch while backup slurmctld and
slurmdbd are running, the job becomes scheduled and runs.
I don't know why, but this is OK.
Thanks,
Hiro
