HA Active / Passive NFS Cluster
Get a Pair of CentOS 5.5 machines serving up Highly available NFS
I use NFS volumes for all of my production vmware servers. As a result, loosing your NFS server to a hardware failure would be a very bad thing.
We accomplish this using drbd, and heartbeat
This Guide assumes you have two identicaly configured systems, with an empty partition on each node that is un-formatted and ready to go. It also assumes a dedicated crossover connection between network cards on both nodes.
This setup was completed on a CentOS 5.5 system, utilizing the centosplus yum repository for drbd and the fedora epel repository for heartbeat.
