Hello Ole, I have no firewall on the computenodes and I have the internal interfaces on kadmin2, opa and eth, in the trusted zone of the firewall. It should allow everything through. I'm using RHEL 9.4. I built the rpm packages from source using the admin guide https://slurm.schedmd.com/quickstart_admin.html : https://slurm.schedmd.com/quickstart_admin.html "Kadmin2" and "headnode" are the one and same. This system is on an air gapped network and I had to hand jam everything. Sorry for the confusion. No luck stopping the firewall service. Still the same issue. I'll continue to read the documentation that you have sent me and see if I missed anything.

What is your OS, and did you install Slurm by RPM packages or what? Does sinfo work on your SlurmctldHost=kadmin2? Is the "headnode" a different host? Try stopping the firewalld service. You can see some advice on firewalls in the Wiki page https://wiki.fysik.dtu.dk/Niflheim_system/Slurm_configuration/#configure-fir... There is information about Slurm installation and configuration in the Wiki pages in https://wiki.fysik.dtu.dk/Niflheim_system/ IHTH, Ole On 11/27/24 15:56, Kent L. Hanson via slurm-users wrote:

You only have one partition named 'default' You are not allowed to name it that. Name it something else and you should be good. Brian Andrus On 11/28/2024 6:52 AM, Patrick Begou via slurm-users wrote:

Hi Kent,

on your management node could you run: systemctl status slurmctld

and check your 'Nodename=....' and 'PartitionName=...' in /etc/slurm.conf ? In my slurm.conf I have a more detailed description and the Nodename Keyword start with an upper case (do'nt know if slurm.conf is case sensitive) :

NodeName=kareline-0-[0-3]  Sockets=2 CoresPerSocket=6 ThreadsPerCore=1 RealMemory=47900

and it looks like your nodes description is not understood by slurm.
