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

Hi Steven,
yes, you have the syntax a bit wrong. If you consult the documentation (or the man-page) of slurm.conf you find this in the "NODE CONFIGURATION" section (in the paragraph about "NodeName"):
Note that if the short form of the hostname is not used, it may prevent use of hostlist expressions (the numeric portion in brackets must be at the end of the string)
So the respective part in your slurm.conf should be
NodeName=node[1-7] ...
and you have to configure your name resolution (default domain?) such that these short names are resolvable to IP-addresses.
If that's not feasible you might have to use e.g. something like this
NodeName=DEFAULT CPUs=20 RealMemory=48 NodeName=node1.ods.vuw.ac.nz NodeName=node2.ods.vuw.ac.nz ...
BTW: do your nodes only have 48 MB of memory? The unit in which "RealMemory" has to be specified is megabytes.
Regards, Hermann

Where is this set?

You don't often get email from jrlang@uwyo.edu. Learn why this is important https://aka.ms/LearnAboutSenderIdentification

Trying running the failing process from the command line and use the -D option.
Per man page: Run slurmd in the foreground. Error and debug messages will be copied to stderr.

Hi,
I have set a log creation/location in slurm.conf as,
SlurmdLogFile=/var/log/slurm/slurmd.log
But it is 0 length.
Slurm will not run, what else do I need to do to log why its failing pls?
regards
Steven
Hello Steven, if its warewulf v4 you can have a look at https://apc01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com...https://github.com/warewulf/warewulf/blob/main/etc/examples/slurm.conf.ww which is a template for a slurm.conf created from the available nodes in warewulf.
kind regards, Christian
