As promised in one of my previous posts about dual-primary DRBD and OCFS2, I’ve compiled a step-by-step guide for Fedora. These instructions should be somewhat close to what you would use on CentOS or Red Hat Enterprise Linux. However, CentOS and Red Hat don’t provide some of the packages needed, so you will need to use other software repositories like RPMFusion or EPEL. In this guide, I’ll be using two Fedora 14 instances in the Rackspace Cloud with separate public and private networks.
