NFS partition not mounting automatically

milomak · 08-28-2010, 11:31 AM

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

Code:

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

Code:

My /etc/network/interfaces looks like

Code:

# 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

#auto eth1
#iface eth1 inet dhcp

iface eth1 inet static
address 10.0.0.1
netmask 255.255.255.0
network 10.0.0.2
broadcast 10.0.0.255

What am I missing?

Although I have posted Debian details above; the same thing happens with my Arch and Fedora installs - that is I have to run mount -a to mount the nfs partition although it is in my /etc/fstab

Use _netdev option.

Try this:

Code:

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

Greetingz!

I would suggest against using /etc/fstab for NFS mounts. Rather, there's a way to have an NFS mount auto mounted/unmounted as needed. Depending on your particular platform, you'll want to read up on the man pages for either auto.master and auto.nfs (or auto_master and auto_nfs).

For my CentOS/RHEL servers, the /etc/auto.net script will find all NFS shares that are shared out to the server, then auto-mount them as needed under /net. So if I setup an NFS share from ServerBravo:/mnt/backups to ServerAlpha, then on ServerAlpha I can "cd" to "/net/ServerBravo/mnt/backups".

Make sense?
