Hi,

I was wondering what are the files included in the conf hash check?

I guess the file acct_gather.conf isn't included as it seems impossible to have the same file for every node as the file depends for example on ipmi sensors. Or is there a way to list all the nodes in this file so we can ensure the file is identical on the whole cluster as well, like we do for the gres.conf file.

Hi Yann,

Only slurm.conf.

acct_gather.conf is allowed to be different for each node, to adapt it to the underlying HW, as you have mentioned.

We don't have the need to specify all nodes in a single acct_gather.conf as slurmctld doesn't really need to know the exact underlying plugin the node is using to grab the metrics. gres.conf needs to be a general one with all nodes in it because slurmctld needs to know all the cluster GRES, so it can properly schedule the jobs.

I'm directly marking the bug as info given but if you need further assistance please reopen it and tell us your thoughts.

Regards,
Carlos.
