[Bug 848823] Re: nfs-kernel-server requires a real interface to be up

[Doug Jones]

This is affecting me as well.  It started when I upgraded from 11.04 to
11.10.

I am identifying machines with IPs, not DNS.  I set it up as per this
tutorial:

https://mostlylinux.wordpress.com/network/nfshowto/

These instructions work fine for 10.04, 10.10, and 11.04.  (However, the
commands it describes for restarting services no longer apply in 10.10
and later;  my workaround has been to simply reboot the machine instead,
and that works fine).

I still have machines running those older versions, and they still talk
to each other,  but the one running 11.10 is incommunicado.

I did get the error message Tim mentioned about "/etc/exports.d: No such
file or directory", but I simply created an empty directory at
/etc/exports.d and that message no longer appears.  But NFS still
doesn't work.

I have tried the workaround Joseph Brown describes but that doesn't seem
to help.

I would like to try the workaround where one uses
/etc/network/interfaces instead of network-manager, but I have no idea
how to do that.  If someone could spell that out, at the user-
friendliness level of the tutorial I mentioned above, that would be
great.

BTW, I know at least two other people who are using NFS on 10.04 LTS,
using basically the same setup I have (from that same tutorial), and who
probably would be upgrading to the upcoming LTS if they hadn't already
been warned about NFS being borked.  I wonder how many other LTS users
are about to get a nasty surprise.

  working again. This is required atleast once per day.
