Hello me again Just found out that when our slurmctld restarts all qos are gone.
I mean users who have association with the qos can not submit job with sbatch, they get error as sbatch: error: Batch job submission failed: Invalid qos specification Do we need to make anymore changes in slurm.conf so that qos becomes permanent ?
