I am curious about free open source tools out there for cloning and deploying nodes in a HPC cluster.
I am working on a hardware cluster built with RHEL6.
All software for the cluster will be installed on an image node, which will not be one of the worker nodes. This software will then be mounted as an nfs share to each of the worker nodes. All of that is tested and working.
What I need to do is build a golden image on one of the worker nodes and clone it to the rest of the nodes. Whenever I need to change the OS on the worker nodes, I will just clone them from the updated golden image.
I have been using SystemImager but it is old and dated and has not been getting any updates. Are there any other free tools out there, or any processes you can recommend to me that would be suitable?
