Hi all, I was trying to rebuild mtr (http://vault.centos.org/6.7/os/Source/SPackages/mtr-0.75-5.el6.src.rpm) and I keep getting: ==== Executing(%install): /bin/sh -e /var/tmp/rpm-tmp.gu9Ds0 + umask 022 + cd /root/rpmbuild/BUILD + '[' /root/rpmbuild/BUILDROOT/mtr-0.75-5.el6.x86_64 '!=' / ']' + rm -rf /root/rpmbuild/BUILDROOT/mtr-0.75-5.el6.x86_64 ++ dirname

Hi all, I'm happy to announce a new tutorial! https://alteeve.com/w/2-Node_Red_Hat_KVM_Cluster_Tutorial This tutorial walks a user through the entire process of building a 2-Node cluster for making KVM virtual machines highly available. It uses Red Hat Cluster services v3 and DRBD 8.3.12. It is written such that you can use entirely free or fully Red Hat supported environments.

I'm not surprised, given that it is in the repo. That's why I was asking if anyone tried building it themselves and, if so, did they have the same issue as I describe below? Alternatively, any tips/advice on solving my build issue would be helpful. digimer On 07/03/16 07:29 PM, Nux! wrote: > It built just fine in mock, results here > http://li.nux.ro/download/nux/tmp/mtr6/ >

Almost exactly two years ago, I released the first tutorial for building an HA platform for KVM VMs. In that time, I have learned a lot, created some tools to simplify management and refined the design to handle corner-cases seen in the field. Today, the culmination of that learning is summed up in the "2nd Edition" of that tutorial, now called "AN!Cluster Tutorial 2".
