FAI with NFS v4 on Debian Wheezy

[Toomas Tamm]

Hello!

This is not a FAI problem, but a more general NFS4 problem. NFSv4 needs
some configuration, and the defaults differ between squeeze and wheezy.
I have done the following:

1) ensure that idmapd is running on the server.
In /etc/default/nfs-common you should have
NEED_IDMAPD=yes
(restard nfs-common manually or reboot to have this take effect)

2) ensure that all idmapd-s have the same value for "Domain". Squeeze
defaults to a portion of your fqdn, while wheezy defaults to
"localdomain". This is set in /etc/idmapd.conf and better make it
identical across your entire network.

A symptom of misconfiguration of (2) are messages like
nss_getpwnam: name 'root at localdomain' does not map into domain 'your.fqdn.com'
in dameon.log.

Other than that, NFSv4 runs out of the box with the 3.2 series kernels.
No need to set up complicated loopback mounts as explained in several
howto's in the net. Apparently that is a thing of the past.

Hoping this helps,

Toomas
