I am trying to make a hpc with rocks CentOS 7. After installing rocks, I have to connect the compute node to master node.

In terminal I have typed out insert-ethers to do the pxe(Preboot Execution Environment). After that I start my compute node with boot option as network pxe . After that it starts but shows this error:enter image description here

I have also tried that I have removed the node by rock remove compute-0-0 and rocks sync config but it's not working.

How can I fix it?
