pcluster update-cluster is deleting slurmdbd service #29

Closed rvencu closed 2 years ago

rvencu commented 2 years ago

Updating the cluster config from the Cloud9 instance is removing the slurmdbd service.

I am not sure maybe there is a personalized update procedure via enginframe portal instead?

rvencu commented 2 years ago

ok, manually starting slurmdbd works, so the config is not broken. But this does not start automatically, there is no service defined and maybe it should.

I do not know if not starting slurmdbd is by design or it should be corrected

nicolaven commented 2 years ago

it should be fixed now, thanks for pointing this out!

hi for some reason the service slurmdbd do not start, whereas launching the script from console works

systemctl status slurmdbd
● slurmdbd.service - Slurm DB controller daemon
   Loaded: loaded (/etc/systemd/system/slurmdbd.service; enabled; vendor preset: disabled)
   Active: inactive (dead) since Mon 2022-07-18 09:28:05 UTC; 33s ago

yes, changing the service to this seems to work:

[Unit]
Description=Slurm DB controller daemon
After=network.target munge.service slurmctld.service
ConditionPathExists=/opt/slurm/etc/slurmdbd.conf

[Service]
Type=oneshot
ExecStart=/opt/slurm/sbin/slurmdbd
ExecReload=/bin/kill -HUP $MAINPID
LimitNOFILE=65536
RemainAfterExit=yes

[Install]
