[Solved] NFS client not mounting NFS mount at boot

[milomak]

I have an NFS mount that is in my NFS client's fstab file

Code: Select all

192.168.1.102:/mnt/mythtv                               /mnt/mythtv     nfs             defaults        0 0

sudo mount -a will mount it after i have booted the system.

However, at boot it is not mounted. An extract of /var/log/boot shows

My /etc/network/interfaces looks like

Code: Select all

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

iface eth1 inet static

What am I missing?

So I have another Debian Sid computer that seems to load the NFS partition correctly. It uses the exact same fstab as the one that doesn't.

I'll trim down and update what I can and see what happens

[smallchange]

Debian has a great packaging system but there is more to running a *nix system than installing packages. What is happening here is that in Debian when a network interface is brought up it runs the scripts in /etc/network/if-up.d, one of which is mountnfs. This script uses a directory "/var/run/network/mountnfs" to know if it is bringing up the last interface so that it mounts the network file systems only once. If your system boot fails in a particular way that directory may be left existing and you will get this behavior. Remove that directory and it will work as it should.

[milomak]

yep you are right. that directory was the cause of the issue.

probably a leftover remnant from an earlier package (the computer that was having problems was built much earlier than the one where there was no problem). or a system crash that didn't remove it.

strangely i see this was previously discussed - http://forums.debian.net/viewtopic.php?f=5&t=45135

I am embarrassed by my search skills
