Have you copied the _exact_ slurm.conf from the master to the compute node?

Check your firewall rules to ensure that those connections aren't
getting blocked, and also check that the hostname correctly resolves.

slurmd, I got the error:

Hi ,

I have installed slurm on a 2 node cluster.
On the master node when I run sinfo command I get below output.
sinfo
PARTITION AVAIL  TIMELIMIT  NODES  STATE NODELIST
debug*   up   infinite  2   idle punehpcdl[01-02]

But on compute node:Slurmd daemon is also running but it gives the error:
Unable to contact slurm controller (connect failure).



I am not able to understand the error , why this error exists.Although in the 
master node sinfo output state of this node is coming out to be idle.

Please help on this.
