[slurm-users] sbatch does not work with Debian image

[Sorin Draga]

Hello everyone,

I'm trying to run the new Debian image with SLURM, namely debian-11-bullseye-v20230206 but sbatch/sinfo do not seem to work. I installed slurm-client via:

sudo apt-get install slurm-client



but it did not solve the problem:

sinfo: error: resolve_ctls_from_dns_srv: res_nsearch error: Unknown host
sinfo: error: fetch_config: DNS SRV lookup failed
sinfo: error: _establish_config_source: failed to fetch config
sinfo: fatal: Could not establish a configuration source



I am using this image because it provides python 3.9.x out-of-the-box.



It might be that the problem is trivial and I am missing something.



Would appreciate your help and insight



Kind regards,



S

this is a hostname resolution issue, you should check your slurm.conf
and related dns resolution

The error message says that slurm cannot find slurm config file. Do you have a local copy of /etc/slurm/* or share the /etc/slurm across NFS, or using DNS & configless slurm?

Sincerely,

Hello everyone and thank you for the feedback,

@Shunran Zang: Indeed, for some reason there is no slurm.conf file in the /etc/slurm/ directory. We previously used the  ShedMD's CentOS images and things worked fine. Could this be due to the Debian GCP image?

Many thanks!

Two of likely several possibilities:

 

The slurm master host name does not resolve.

The rights on /etc/slurm are such that the user running the command cannot read /etc/slurm/slurm.conf
