Fatal: module nfs not found

Question

I am setting up a new NFS client on a LAN that has a working NFS server (Ubuntu 12.04) running nfs4. The other clients all work as expected.

On this new client I'm running ChrUbuntu with kernel 3.4.0 (Kubuntu 12.04) on an Acer Chromebook. I installed nfs-common. However, the mount command returns the error mount.nfs4 no such device. And # modprobe nfs returns Fatal: module nfs not found. Google didn't offer me any solutions.

The mount command is like:

sudo mount -t nfs4 -o _netdev,noatime,auto,rw myserver:/home/user/shared /home/user/mountpoint

The modprobe command is:

sudo modprobe nfs

And nfs-common is the latest version from this release's repo: 1:1.2.5-3ubuntu3.1

modprobe is looking in /lib/modules to know whether a module is present. So you should check first if the current version of your running kernel has nfs module:

ls -l /lib/modules/$(uname -r)/kernel/fs

if you don't see nfs folder, it means the nfs module is not compiled for your running kernel. You can recompile kernel to make it use nfs module. However, you should upgrade your kernel first:

sudo apt-get update
sudo apt-get dist-upgrade
sudo init 6
