[PROBLEM] Moode find my Nas but not the library

[romain64]

Thank for you help, 
192.168.0.18 is ip adress of my nas
192.168.0.17 is my ip adress of my moode player
my shared folder / music : Now, I created a authorization nfs for 192.168.0.0/24 
And I click on update mpd but nothing happen

With my iPhone, I use app folder,  I connected to server with 192.168.0.18 and I acceded to music and play the song. Maybe because I checked SMB,AFP,NFS in service
folder?
Anyway the problem persist : the source has a tick next to it in the moode's library page, but mpd is not finding any file.

This is unlikely to be a Moode issue, more likely to do with the options on your NFS share on the NAS or file permissions on the shared files.

You could access the mounted filesystem in a shell if you wish, as follows...

•    Goto to [Configure] > [System] > [Local Services] and ensure [SSH term server] is enabled.
  
•    Once enabled select the [Open] button for Web SSH terminal
  
•    Login as user pi with the password moodeaudio
  
•    At the prompt you can see any NFS mounts with...
  

Code:

mount| grep nfs

     ... which should show your /mnt/NAS/musique mountpoint

•    List the contents of the share with
  

Code:

ls /mnt/NAS/musique

•    Test to see if the mpd user can see any mp3 files on your share...
  

Code:

sudo su - mpd -c 'find /mnt/NAS -iname "*mp3" '

Hope that helps

It's going to be more complicated, I follow your instructions step by step:
I think you are right, the problem comes from the nas.
I send you a capture of the terminal screen. So now what should happen?
Thank a lot
