We recently has a job to implement a compute cluster with HA-Frontend and Lustre file system as cluster file system. A piece of this job that’s not really easy to achieve is Dual-Frontend with HA capability. Anyways, after few days of tweaking and digging, I can finally made a HA-Frontend for ROCKS 5.1 that could work in some level. I would like to share this experience with anyone who interest in similar topics.

Note that, this tutorial is created AFTER I finished the job. During the job, I note down as much as possible what I have been doing, but some details might be accidentally left over. Use it at your own risk!
