[DRBD-user] Fault Tolerant NFS

[J.R. Lillard]

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.
