[slurm-users] sinfo: error: resolve_ctls_from_dns_srv: res_nsearch error: Unknown host

[Michael Lewis]

Hi All,

I’m trying to get slurm-23.11.3 running on Ubuntu 20.04 and running on a stand alone system.  I’m running into an issue I can not find the answer to.  After compiling and installing when I fire up slurmctld and slurmd I get an error from sinfo:


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 looks like a DNS issue but the system has no issue resolving to its hostname or localhost.  The slurm.conf file is also being read properly as I have the logs directed to a place convenient to me.  I see lots have had these same issues but cannot find a clear resolution.

I have slurm running on a stand alone system in another lab with and identical setup without issue.  Any advice would be greatly appreciated.

Thanks,

Mike
