Mounting points

IP addresses

local: 192.168.1.16
remote: 192.168.1.191

1) We will mount

Source:     remote:/srv/share/app/docs
Destination: local:/srv/app/static/data/docs

2) We will mount

Source:     local:/srv/app/static/data/docs
Destination local:/var/app/app/static/data/docs

Mount remote: in local:

/etc/fstab:
-----------
...
192.168.1.191:/srv/share/app/docs   /srv/app/static/data/docs   nfs  noauto,x-systemd.automount,x-systemd.device-timeout=10,timeo=14,x-systemd.idle-timeout=1min 0 0

Since the fstab will not be loaded until we reboot the host, we can mount it manually:

_$: mount \
-t nfs \
-o noauto,x-systemd.automount,x-systemd.device-timeout=10,timeo=14,x-systemd.idle-timeout=1min \
192.168.1.191:/srv/share/app/docs /srv/app/static/data/docs
