nfs-kernel-server does not start after reboot

Question

After installing the nfs server it does not run. After manually sztarting the rpcbind and nfs-kernel-server service everything works fine, but after a reboot it is again not running.

Answer 1

After evaluating tons of answers and threads about this topic I found a quite simple solution.

The problem is that the rpcbind service is not started. This can be achieved just by adding the correct dependencies for the nfs-kernel-server service. Add an approipriate drop-in for this service. For example

/etc/systemd/system/nfs-kernel-server.service.d/10-dep.conf:

[Unit]
  Requires=rpcbind.service
  After=rpcbind.service

Now reboot works fine without any strange sleep commands in service scripts.
