Solving NFS Mounts at Boot Time(Today’s post is brought to you by the letters N, F, and S. Oh, and Scott Pack too.)Let’s face it. NFS is a magical thing. It allows you to centralize your storage, share volumes across systems, and all while maintaining sane permissions and ownership. Unfortunately, it can also be a bit of a fickle beast. Let’s say you just had your volume configured and you set up the mounts. You go and run this command: mount - t nfs 1.

Works like a champ, you now have your data partition mounted over NFS. So you add this line to your /etc/fstab and make it mount automagically.

A few weeks go by and you apply a kernel update. No big deal, you apply the updates and during your next maintenance window reboot to apply the new kernel. Then you start to see applications failing and notice the volume isn’t actually mounted. This is an unfortunate result of the automounter subsystem. It’s like this. At boot time the root partition gets mounted, automounter reads the /etc/fstab file, and boots any filesystem that doesn’t have noauto as a mount option. We’re still very early in the boot process so the network isn’t up yet, so naturally any network filesystems fail. The real problem here is that at no point does automounter go back and attempt to remount those systems.

Ware) mount points. This is exactly what you need. It is a service whose sole purpose is to read your /etc/fstab and mount network filesystems. All you have to do is enable itchkconfig netfs onand watch the magic happen. Now your mount boot process should look something like this: Automounter reads /etc/fstab. Ignores /data since it has . I had even gone so far as to start planning out my own custom init script that would do exactly this, except specifically for my mount points instead of generalizing.

It’s nice to see that I was on the right track, but even better that the tools already existed.
