Just because there is a ping connection doesn't mean that slurmctld can
talk to the Slurm clients. Look for a firewall between the server and
the nodes that is blocking the port used by Slurm.

Hi All
I'm new here its my 1st time :-) . happy to meet u
not sure if its the right mail list
let me ask pls
i have such problem :
slurm server ip 192.168.10.1
compute nodes 10.2.2.3-40
Until yesterday the compute nodes were in the same VLAN as the slurm ,
but i had to move them to new VLAN.
After i moved them there is ping connection between slurm server and the
compute nodes and reverse.
slurm.conf was updated at slurm server and compute nodes with the new IP
Address.
When changing the state of the compute nodes to IDLE they looks ok for
some time - 1, 2 , 5 minutes and then goes DOWN
The error at slurm server slurmctld shows nodes not responding..
Does anyone had such issue or any have any idea how can be solved ?
Thank u !!
Best Regards
