Hello, I am not aware of fencing.Yes you are correct i have not configured anything related to fencing. Can you please let me know as how can i proceed...Do i have to purchase some sort of hardware? How can i implement Power Fencing? I am using virtual box machines on my desktop in which linux are installed and have been connected through swtich.

Hence they may not have IPMI/ILO etc. I am 99.99% certain that fencing has not been configured. I also doubt if it has external storage. (I can identify as I tried my experiments with clusters first time with such desktop class machines) The only solution for this is Power Fencing. -- Regards, Rajagopal -- Linux-cluster mailing list <a href="mailto:Linux-cluster@redhat.com" target="_blank">Linux-cluster@redhat.com</a> <a href="https://www.redhat.com/mailman/listinfo/linux-cluster" target="_blank">https://www.redhat.com/mailman/listinfo/linux-cluster</a> </blockquote></div>
