Created page with "To change the Head node's hostname, the typical CENTOS hostname changing procedure must be followed: * Edit the /etc/sysconfig/network file and change the HOSTNAME variable to..."

New page

To change the Head node's hostname, the typical CENTOS hostname changing procedure must be followed:
* Edit the /etc/sysconfig/network file and change the HOSTNAME variable to the desired name
* Run
hostname <new hostname>
* Reboot the head node for all the changes to be visible in the CMGUI

Everything should work fine by now. The only thing noted is that when a compute node pings the new head node's hostname, the old hostname is visible (although the IP is resolved). If this is a problem, re-install the compute nodes.
