I'm setting up a new test cluster with SLURM 15.08.5 (we run Torque/Maui
on our production cluster). We have a SLURM master server running
CentOS 7.2 and two compute nodes on separate subnets (10.1.. and
10.2..). I'm writing a SLURM installation HowTo page as I go along:
https://wiki.fysik.dtu.dk/niflheim/SLURM
I'm now facing a problem running a trivial test:
# srun -N1 --constraint="opteron4" /bin/hostname
srun: error: Unable to allocate resources: Requested node configuration
is not available
Question: What may be causing the available node with property
"opteron4" to reject jobs?
The other partition works just fine:
# srun -N1 --constraint="xeon8" /bin/hostname
a012.dcsc.fysik.dtu.dk
FYI, the node status is:
# scontrol show nodes

I believe that the nodes are configured identically, except for their
hardware differences.
