Thank you for your quick reply
Sorry if I am not being clear. I am using this as a media server so I want to access all the files from the array and the NAS in the same folder (simply because it is more tidy) without creating a symlink.
My fstab looks like this:
UUID=543717ae-3aa5-476e-bc19-df43a0f7e9c4 /files/archive2 ext4 defaults 0 2
192.168.1.18:/volume1/Archive2/ /files/archive nfs nouser,atime,auto,rw,dev,exec,suid 0 0
Now, it works of course, but if I mount them both to the same folder it does not.
