+==== Slurm logging ====
+The Slurm logfile directory is undefined in the RPMs since you have to define it in slurm.conf. See SlurmdLogFile and SlurmctldLogFile in the slurm.conf page, and LogFile in the slurmdbd.conf page.
+Check your logging configuration with:
+<code>
+grep -i logfile /etc/slurm/slurm.conf
+</code>
+<code>
+SlurmctldLogFile=/var/log/slurm/slurmctld.log
+SlurmdLogFile=/var/log/slurm/slurmd.log
+</code>
+<code>
+scontrol show config | grep -i logfile
+</code>
+<code>
+SlurmctldLogFile        = /var/log/slurm/slurmctld.log
+SlurmdLogFile           = /var/log/slurm/slurmd.log
+SlurmSchedLogFile       = /var/log/slurm/slurmsched.log
+</code>
+If log files are configured, you have to create the log file directory manually:
+<code>
+mkdir /var/log/slurm
+chown slurm.slurm /var/log/slurm
+</code>
 Study the configuration information in the [[https://slurm.schedmd.com/quickstart_admin.html|Quick Start Administrator_Guide]].
+===== Home Users =====
+For the users folder, you can use the server's local disk or mount the remote storage. For this reason it is recommended to create a folder to put the information of the users. In this example we created a folder /home/CLUSTER and here we create the folder for every users.
+<code>
+mkdir /home/CLUSTER
+</code>
+===== Creating users =====
+For the users you can crate every user manually o you can user an external user database how Active Directory, OpenLDAP or MySQL, etc.
+For this example we going to create the users manually in every server.
