You need quite a lot of services and some pseudo file systems mounted for nfs to work properly. When I switched to systemd there weren't any service files so I wrote my own. Took me a while, since it was a bit of a hassle to find out the right order and what I actually need. This is my setup for nfsv4:
proc-fs-nfsd.mount:

The rpc.[svc]gssd services are only needed if you use nfsv4 with kerberos authentication. Enable rpc.gssd on the client and rpc.svcgssd on the server.
The rpc.mountd and rpc.statd, as well als sm-notify services are only necessary if you are using nfsv3 shared. Enable the first two on the server if you export nfsv3 shares, and sm-notify on the client.
To make it a little easier, these are the services you need to enable on the server:
Code:
systemctl enable var-lib-nfs-rpc_pipefs.mount
systemctl enable proc-fs-nfsd.mount
systemctl enable rpcbind.service
systemctl enable rpc.idmapd.service
systemctl enable rpc.nfsd.service
systemctl enable exportfs.service
# for NFSv3 only:
systemctl enable rpc.mountd.service
systemctl enable rpc.statd.service
# for NFSv4 kerberos auth only:
systemctl enable rpc.svcgssd.service
# finally, enable nfs.target to start services at boot:
systemctl enable nfs.target
on the client:
Code:
systemctl enable rpcbind.service
systemctl enable var-lib-nfs-rpc_pipefs.mount
systemctl enable rpc.idmapd.service
# for nfsv3 only:
systemctl enable sm-notify.service
# for nfsv4 kerberos auth only:
systemctl enable rpc.gssd.service
# finally, enable nfs.target to start services at boot:
systemctl enable nfs.target
Of course you need to add a "After=remote-fs-pre.target" in the [unit] section to any .mount unit on the client that should mount an nfs share.
Hope those files can help you.
