Hello, I'm trying to get SLURM set up on a small cluster comprised of a head node and 4 compute nodes. On the head node, I have run
``` sudo systemctl enable slurmctld ``` but after a reboot SLURM is not running and `sudo systemctl status slurmctld` returns: ``` ● slurmctld.service - Slurm controller daemon Loaded: loaded (/lib/systemd/system/slurmctld.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Tue 2017-09-19 10:38:00 EDT; 9min ago Process: 1363 ExecStart=/usr/sbin/slurmctld $SLURMCTLD_OPTIONS (code=exited, status=0/SUCCESS) Main PID: 1395 (code=exited, status=1/FAILURE) Sep 19 10:38:00 arcesius slurmctld[1395]: Recovered state of 4 nodes Sep 19 10:38:00 arcesius slurmctld[1395]: Recovered information about 0 jobs Sep 19 10:38:00 arcesius slurmctld[1395]: Recovered state of 0 reservations Sep 19 10:38:00 arcesius slurmctld[1395]: read_slurm_conf: backup_controller not specified.

Sep 19 10:38:00 arcesius systemd[1]: slurmctld.service: Failed with result 'exit-code'. ``` If I then run `sudo systemctl start slurmctld`, it starts up without any errors and my compute nodes can communicate with the server. Launching `slurmctld -Dvvvvvv` works, and doesn't print anything that I deem concerning. Why would it work manually, but not automatically on boot? If you need any more information, please let me know; I'm not sure what is necessary to diagnose this problem. Thank-you, KM
