I have installed an NFS File Server on Ubuntu 11.10, and that is working well.

I am only able to connect to the NFS server from my Mac with this command:

 mount -t nfs -o vers=4 10.0.10.26:/srv /Users/admin/Desktop/mount

But I cannot connect via Finder (nfs://10.0.10.26:/srv) or through any third party programs that don't allow for the version parameter. The Syslog error is

mount_nfs: can't mount /srv from 10.0.10.26 onto /Users/admin/Desktop/mount: Program version wrong

Is there any way to set this to V4 by default? Either server side or on my Mac? I need to be able to connect without the extra parameters.

Thanks

This question came from our site for professional and enthusiast programmers.

The syntax for using NFS v4 (and passing options in general) is :

nfs://vers=4,10.0.10.26/srv

You can check the mount afterwards from the Terminal using :

nfsstat -m

I found (OSX 10.9.5) that this was no good. The comma ends up in the mount command. Investigating the command it ran (from the ps list) I saw that this resulted in a command: mount_nfs -odeadtimeout=45 nfsvers=2,example.com:/var/www /Volumes/www - which was a failure. Experiments with other variations of spacing before the hostname seemed to help a little. Entering an nfs URL nfs:// -onfsvers=2 example.com:/var/www - Including those spaces looked like it should have worked, but for some reason still did not. – dman Dec 10 '14 at 2:13

Hmmm, seems we need to have this question re-answered every major release of OS X.

So I can only say this works on 10.10.x :)

From OS X's man page for mount_nfs

"nfs.conf(5) can be used to configure some NFS client options. In particular, nfs.client.mount.options can be used to specify default mount options"

To get the Finder to default to using NFS v4 add the following to /etc/nfs.conf using the terminal command "sudo vi /etc/nfs.conf"

 nfs.client.mount.options = vers=4

Again, to check after mounting use "nfsstat -m" and check the "NFS parameters".
