NFS is very different than HTTP, so unless you have other software that encapsulates NFS in HTTP, I doubt that config will actually work. I found the following blog post about doing highly available NFS with haproxy. I think the page is in Hungarian, but the haproxy config is readable. Try Google Translate if you really want to read the post and don't understand that language. I can't read the original page, but Google's english translation looked pretty good. https://blog.xorp.hu/haproxy-high-available-nfs Thanks, Shawn
