NFS lose UID - GID once mounted

Hello,

I am a beginer on OMV.

I am trying to share folder through NFS but once mounted is always owned by anonymous.

In detail :
I created a shared folder
I added it to NFS

The /etc/exports shows :
export/Films 192.168.0.10(rw,subtree_check,secure,all_squash,anonuid=1000,anong
id=1000)

# NFSv4 - pseudo filesystem root
/export 192.168.0.10(ro,fsid=0,root_squash,no_subtree_check,hide)

I mounted the shared directory with :
~$ sudo mount -t nfs -o rw 192.168.0.44:/Films /home/olivier/Video_Serveur

The file owner's UID is 1000 on OMV.

It is the same UID that is mounting on the client side

But once mounted the files are belonging to anonymous

$ ls -l /home/olivier/Video_Serveur/
total 2368
-rw-rw-r-- 1 nobody users 83149 févr. 5 2013 Capture du 2013-02-05 21:25:02.png
drwxrwxr-x 12 nobody 4294967294 4096 mai 3 2012 FilmDVD
-rw-r--r-- 1 nobody users 2334208 déc. 31 2010 SCN_0013.pdf

I tried the sale operation with another NFS server (on a ubuntu machine) and the files are showing the correct owner once mounted on the client.

Could you please help me ?

The FS is mounted under /media on OMV.

That's the corresponding command you can see the owner is Olivier whose UID is 1000.

Thanks for your help.

I am not really sure I understood your comment. I didn't change any permission. I just selected an existing folder and add it as a share one and then use it for NFS.

I am starting this OMV as a backup machine.

I may be doing this the wrong way but my objective is to mount the OMV folder on a client machine to run a backup (using lucky backup).

In a previous test I did many months ago if the owner were wrong the backup messed up and was backuping all the files all the times.

I didn't go until the test with Luckybackup, since I stopped when I found this situation.

My previous test were with sshfs but I red that NFS would be better for a continuous connection.

Thanks very much for your help David.

I have to go too. It's a liitle bit late here ...

I'll try tomorrow and keep watching your answer.

Hey David,

I made some afdditional testing.

My current situation (permissions not being root - users on the server side) is due to the use of existing disks with existing FS that came with permissions that OMV kept as they were.
I created a new FS from OMV on an empty partition and everything is set to root - users as expected.

However mouting throough NFS I still getting root - users on the client side.

I tested CIFS -Samba
I have the issue of permissions on the client side (regardless of the protocol used : NFS or Samba).

So, on the client side I added the user (olivier) to the group users and my backup program is able to run correctly.
We can consider that I have a solution.
But I still do not understand why the ANONUID and ANONGID is not working with NFS.

By the way, Samba it looks like Samba is running better and faster than NFS. Therefore I am getting rid of NFS and switching to CIFS, it's a shame as all my machines are running Linux.

Thanks again David.
