NFS-kernel-server starting before fstab and fails

Hello there,

im setting up an iscsi Drive for the home directory. It works except the nfs-kernel-server cant start because he starts before the fstab mount and gets problems with the marketplace share.
I can manually restart the service after the boot is completed and it works.

I cant find the setting to switch the order…

I probably have to do smth like:

But I cant find the nfs-kernel-server.service file

Thanks for help
