Nfs failed in joomlatools box

[Yves Dangel]

Hi everybody,

I needed to reinstall my system on new ssd/motherboad but I have some problems with vagrant joolabox on my new debian 8.2 host. (all was working before)
Mismatch of virtualbox guest addon was solved when updating vagrant to 1.8 and virtualbox to 5.0 but a nfs problem remains.

With vagrant ssh, I was able to install a test site with
sudo joomla site:create test   (without sudo the command didn't complete)

but I cannot modifiy source files on my host because ~/Dev/jbox/www folder is empty.

The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!

mount -o 'vers=3,udp' 33.33.33.1:'/home/yves/Dev/jbox/www' /var/www

Stdout from the command:



Stderr from the command:

stdin: is not a tty
mount.nfs: requested NFS version or transport protocol is not supported

nfs-kernel-server is installed on host and nfs module is loaded on both client and host.
IP Adress 33.33.33.1 is pingable from client.
I cannot see anything in client log about this problem.

What does I need to check to solve that ?

Thanks for your help

Hello,

I suppose you checked already your firewall settings...

If not, please do so.

Did you try emptying your /etc/exports folder and restart your nfs-kernel-server.service after that.

This seems to work is some cases.

I see you are working in your home directory. Is is encrypted by any chance? This could also cause this type of error.

If so, you could move your working directory out of your home directory.

Good luck,

Peter

Hello Peter,

I have no firewall and ping can success from host to client and from client to host.
i have no encrypted home directory so it doesn't seem to be the problem.
No luck.

I will try again to google same issue but as far as I searched, i didn't find a solution.
A lot of issues on Mac...

Thanks for your help.

More info :


sudo mount -v -o 'vers=3,udp' 33.33.33.1:'/home/yves/Dev/jbox/www' /var/www
gives

mount: no type was given - I'll assume nfs because of the colon

Hello Yves,

It seems that NFS server isn't running at all based on the output you posted from the rpcinfo -p command. If you were to look for the keyword nfs only you should get the following result:

{20:29}[5.5.32]~/:master ✓ ➭ rpcinfo -p | grep nfs 
    100003    2   udp   2049  nfs
    100003    3   udp   2049  nfs
    100003    2   tcp   2049  nfs
    100003    3   tcp   2049  nfs

If you run  ps -aef | grep nfs  you should see the nfs daemon in the output (/sbin/nfsd or similar).

Does it work if you start it manually? I 'm not 100% sure about the correct command for your system, but something along these lines should do it: /etc/init.d/nfs-kernel-server start

If it works then it means the service fails to start properly at boot time (for example wrong startup ordering). 

Good luck,

Steven
