Tha was the problem, I was running at "/home/user" folder and still
got the same issue.
Now I realized that "/home" was a very different folder on nodes, so I
removed "/home" on nodes, exported "/home" from server with nfs and
mounted on nodes. Now it is running great !

just for the records
(on server, 192.168.100.0 is the network, 255.255.255.0)
/etc/exports
/home 192.168.100.0/255.255.255.0(rw)

 (on nodes, 192.168.100.100 is server IP )
/etc/fstab
192.168.100.100:/home /home nfs rw,addr=192.168.100.100,users 0 0

Thank you guys.
