Montage NFS

Serveur

sudo vi /etc/exports

This application updates the current table of exports available to the NFS server.
sudo exportfs -ra

Client
sudo apt-get install nfs-common

sudo systemctl start rpcbind
sudo systemctl status rpcbind

sudo systemctl start nfs-common
sudo systemctl status nfs-common

$ sudo systemctl enable nfs-common
Synchronizing state of nfs-common.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable nfs-common
Failed to enable unit: Unit file /lib/systemd/system/nfs-common.service is masked.

It appears that the unit file has a symbolic link to /dev/null:

$ file /lib/systemd/system/nfs-common.service
/lib/systemd/system/nfs-common.service: symbolic link to /dev/null

I was able to unmask the service by removing the file:

$ sudo rm /lib/systemd/system/nfs-common.service

Then reloading the daemon:

$ sudo systemctl daemon-reload

As we can see the nfs-common service is not running:

$ sudo systemctl status nfs-common
● nfs-common.service - LSB: NFS support files common to client and server
   Loaded: loaded (/etc/init.d/nfs-common; generated; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:systemd-sysv-generator(8)

Let’s go ahead and start the service:

$ sudo systemctl start nfs-common
$ sudo systemctl status nfs-common
● nfs-common.service - LSB: NFS support files common to client and server
