====Update slurm1====
Désactiver les services slurm:
<code>
(baobab)-[root@slurm1 ~]# systemctl disable slurmdbd
(baobab)-[root@slurm1 ~]# systemctl disable slurmctld
</code>

Stopper les services slurm:
<code>
(baobab)-[root@slurm1 ~]# systemctl stop slurmctld 
(baobab)-[root@slurm1 ~]# systemctl stop slurmdbd
</code>

Update Yum:
<code>
(baobab)-[root@slurm1 ~]# yum versionlock delete *slurm*
(baobab)-[root@slurm1 ~]# yum update 
</code>

Si tout est OK, rallumer slurmdbd pour lancer la conversion de la base (surveiller les logs):
<code>
(baobab)-[root@slurm1 ~]# tail -f /var/log/slurm/slurmdbd.log
(baobab)-[root@slurm1 ~]# systemctl start slurmdbd
</code>

Une fois la conversion fini, éteindre slurmctld et lancer salt-check slurm pour vérifier, si tout est OK => salt-apply slurm
<code>
(baobab)-[root@slurm1 ~]# salt-call --state-output=changes state.sls slurm test=true
(baobab)-[root@slurm1 ~]# salt-call --state-output=changes state.sls slurm
</code>

Vérifier les services slurm et la conf:
<code>
(baobab)-[root@slurm1 ~]# systemctl status slurmctld slurmdbd
(baobab)-[root@slurm1 ~]# less /etc/slurm/slurm.conf
</code>
Valeur a vérifier (sans ça le service ne démarre pas):
  * TaskPlugins=task/affinity
  * AccountingStoreFlags=job_comment



Enfin lancer le salt-apply:
<code>
(baobab)-[root@slurm1 ~]# salt-call --state-output=changes state.apply
</code>
