slurmd on a warwwulf node - not running
by Steven Jones 04 Dec '24

04 Dec '24

Hi, I have munge running on the controller and nodes fine, all tests passed. I have slurmctld running on the controller ok after checking the logs /var/spool/slurmctld was not created which I assume should have happened via the rpm install? Anyway I cant get slurmd to run on the warewulf nodes and cant find any log to check? How to fault find this? regards Steven

How can I make sure my user have only one job per node (Job array --exclusive=user,)
by Oren 03 Dec '24

Hi, I have a cluster of 20-nodes, and I want to run a jobarray on that cluster, but I want each node to get one job per node. When I do the following: #!/bin/bash #SBATCH --job-name=process_images_train # Job name #SBATCH --time=50:00:00 # Time limit hrs:min:sec #SBATCH --tasks=1 #SBATCH --cpus-per-task=4 #SBATCH --mem=50000 #SBATCH --array=0-19# 19 # Job array with 20 jobs (0 to 19) I get 10 jobs in node #1 and 10 jobs in node #20, I want a job in each node. I've tried: #SBATCH --exclusive=user Also #SBATCH --spread-job #SBATCH --distribution=cyclic Nothing changes, node#1 got 10 jobs and node#2 got 10 jobs. Thanks

multiple conf-server entries for sackd
by Brian Andrus 03 Dec '24

03 Dec '24

Not sure anyone would know, but... If you are running slurm in HA mode (multiple SlurmctldHost entries) is it possible to point sackd to more than one using the --conf-server option? So either specify --conf-server more than once, or have a comma-delimited list of them? The docs are a little light about that. Brian Andrus

sinfo not listing any partitions
by Kent L. Hanson 02 Dec '24

02 Dec '24

I am doing a new install of slurm 24.05.3 I have all the packages built and installed on headnode and compute node with the same munge.key, slurm.conf, and gres.conf file. I was able to run munge and unmunge commands to test munge successfully. Time is synced with chronyd. I can't seem to find any useful errors in the logs. For some reason when I run sinfo no nodes are listed. I just see the headers for each column. Has anyone seen this or know what a next step of troubleshooting would be? I'm new to this and not sure where to go from here. Thanks for any and all help! The odd output I am seeing [username@headnode ~] sinfo PARTITION AVAIL TIMELIMIT NODES STATE NODELIST (Nothing is output showing status of partition or nodes) Slurm.conf ClusterName=slurmkvasir SlurmctldHost=kadmin2 MpiDefault=none ProctrackType=proctrack/cgroup PrologFlags=contain ReturnToService=2 SlurmctldPidFile=/var/run/slurm/slurmctld.pid SlurmctldPort=6817 SlurmPidFile=/var/run/slurm/slurmd.pid SlurmdPort=6818 SlurmdSpoolDir=/var/spool/slurmd SlurmUser=slurm StateSaveLocation=/var/spool/slurmctld TaskPlugin=task/cgroup MinJobAge=600 SchedulerType=sched/backfill SelectType=select/cons_tres PriorityType=priority/multifactor AccountingStorageHost=localhost AccountingStoragePass=/var/run/munge/munge.socket.2 AccountingStorageType=accounting_storage/slurmdbd AccountingStorageTRES=gres/gpu,cpu,node JobCompType=jobcomp/none JobAcctGatherFrequency=30 JobAcctGatherType=jobacct_gather/cgroup SlurmctldDebug=info SlurmctldLogFile=/var/log/slurm/slurmctld.log SlurmdDebug=info SlurmLogFile=/var/log/slurm/slurmd.log nodeName=k[001-448] PartitionName=default Nodes=k[001-448] Default=YES MaxTime=INFINITE State=up Slurmctld.log Error: Configured MailProg is invalid Slurmctld version 24.05.3 started on cluster slurmkvasir Accounting_storage/slurmdbd: clusteracct_storage_p_register_ctld: Regisetering slurmctld at port 8617 Error: read_slurm_conf: default partition not set.
