How to mount NFS share using systemd

This is an extension to an older blog post on how to mount WebDAV share using systemd as this proved to be a very reliable method that is easy to mark as a dependency for other services.

Install nfs-common package to mount NFS share.

$ sudo apt-get install nfs-common

Create a mount directory.

$ sudo mkdir /mnt/usr-export-from-main-server

Escape mount directory name so it can be used to name the systemd unit file.

$ systemd-escape /mnt/usr-export-from-main-server
mnt-usr\x2dexport\x2dfrom\x2dmain\x2dserver

Verify that the unit name will match the mount path.

$ systemd-escape --unescape --path  'mnt-usr\x2dexport\x2dfrom\x2dmain\x2dserver'
/mnt/usr-export-from-main-server

Create a systemd mount unit configuration.

$ cat << EOF | sudo tee '/etc/systemd/system/mnt-usr\x2dexport\x2dfrom\x2dmain\x2dserver.mount'
[Unit]
Description=Mount NFS share
After=network-online.target
Wants=network-online.target

[Mount]
What=192.168.50.151:/usr
Where=/mnt/usr-export-from-main-server
Options=auto
Type=nfs
TimeoutSec=60

[Install]
WantedBy=remote-fs.target
EOF

Reload systemd manager configuration.

$ sudo systemctl daemon-reload

Enable the mount service at boot time.

$ sudo systemctl enable 'mnt-usr\x2dexport\x2dfrom\x2dmain\x2dserver.mount'

Start the mount service right away.

$ sudo systemctl start 'mnt-usr\x2dexport\x2dfrom\x2dmain\x2dserver.mount'

Finally, check service status.

$ sudo systemctl status 'mnt-usr\x2dexport\x2dfrom\x2dmain\x2dserver.mount'
