This isn't the officially preferred method but it works for us. Instead of using Pacemaker, Corosync and OCFS2 we just use ucarp. All of your switching is handled via /etc/network/interfaces. You'll want to disable NFS from starting automatically at boot. I also disable DRBD from starting at boot. Under my normal interface I post-up / pre-down commands to start / stop DRBD and bring my resources up / down. You'll also have your ucarp config in there which sets up your shared IP. Then on the ucarp virtual interface you use post-up / pre-down commands to promote / demote your server, mount / unmount the filesystem and start / stop the NFS service. Using this setup I can reboot one of my DRBD nodes and my ESXi hosts don't even notice the downtime.<div>
