    Hello, Thanks for the tutorial. Am wondering if these packages are available for debian-based distros such as Ubuntu too?

    • Thilina Uvindasiri says:


      cman you can use. But i dont think ricci, luci and other packs are available. You may use corosync, pacemaker, pcs etc. on ubuntu

    Hi Thilina, what´s about haproxy?

    • Thilina Uvindasiri says:


      HA proxy is also a reputed tool for the same purpose. And is used by many industrial giants. You can expect an article for HA in near future.

    Hi, first, I want to congratulate you for your website and excellent tutorials!! Great job and thanks for sharing your knowledge.. My doubt is about the Cluster Management Server, what if it fails? Is there a solution within the clustering system, or it is necessary to implement a contingency plan?

    Thanks in advantage!

    • Thilina Uvindasiri says:

      Hi Heriberto,

      Thank you for your interest for the post. For the question you ask, It is necessary to implement a contingency plan if you have critical and important data in the cluster. You can setup a fail-over for the cluster management server and services. But this way, it will cause additional costs for the resources. I will share with you if I could find a different and more convenient solution regarding this.

    Hi Dipanjan,

    For two different geographical DC location, you may prefer GRID computing.

  9. Mohammad Ariful Islam says:

    I am eagerly waiting for your next article. Please make it hurry if you can. Thanks.

  10. Dipanjan says:

    There is another big disadvantage in rhel cluster that we are facing everyday in our environment. That is red hat officially does not support extended distance (xd or stage) cluster,that located on two different geographical DC location. Even no solution for this.
