Hi, Thanks, DNS is broken on my warewulf nodes it seems for some reason, but it cant find the controller's IP for some reason.
I had already swapped to, NodeName=node[1-7] and that works OK but not tested much yet. TY for the MB headsup, I had assumed GB. So I assume 48 x 1024? This is a PoC (proof of concept) so some VM nodes with some old nodes thrown in just to test if I can build a HPC. regards Steven ________________________________ From: Christian Goll via slurm-users <slurm-users@lists.schedmd.com> Sent: Thursday, 5 December 2024 3:35 am To: slurm-users@lists.schedmd.com <slurm-users@lists.schedmd.com> Subject: [slurm-users] Re: Slurm not running on a warewulf node On 04.12.24 11:30, Hermann Schwärzler via slurm-users <slurm-users@lists.schedmd.com> wrote: > Hi Steven, > > yes, you have the syntax a bit wrong.
