You are write in that you need a cluster-aware file system like GFS2, which I use, or OCFS2. The most important thing you need to make dual-primary safe is to have a fence device. This is a mechanism for forcing one of the nodes to power off if the communications between the node breaks. This can be provided by a cluster resource manager like Red Hat's cluster service or pacemaker. Beyond this, the topic starts to get more complex. If you want more advice, you will need to be a little more specific on what it is you want to do. -- Digimer Papers and Projects: https://alteeve.ca
