Hetzner-NFS-VLAN.md

Connect 2+ servers hosted on Hetzner using NFS and VLAN.

Note 1: This comes with no support other than the instructions provided here.

Note 2: This setup has been tested to work with standard Unionfs/Rclone VFS setup. Using either MergerFS or any non-standard setup will require you to tweak the appropriate mounts. You can look at the roles to see what changes need to be done.

Install

In this example, we'll set our Feederbox as the NFS server and our Mediabox as the NFS client - this is so that the feeder data can be available to the media server.

There are 3 phases to the setup. They are broken down below.

Hetzner Robot

1. Log into Hetzner Robot.

2. Create a VLAN (vSwitch) and add servers to it. Note the VLAN ID.

   

3. Setup Firewall.

   • Mediabox:

     

   • Feederbox:

     

NFS Server (Feederbox)

1. Setup the Ansible role config.

   1. Add vlan_id.

   2. mount_client setting is ignored for the NFS server (i.e. it will just use 2).

      cd ~/community
      nano hetzner_nfs.yml
      

      hetzner_nfs:
        vlan_id: 4001
        mount_client: 3

2. Run Ansible role to configure the NFS server.

   sudo ansible-playbook community.yml --tags hetzner_nfs_server
   

NFS Client (Mediabox)

1. Setup the Ansible role config.

   1. Add vlan_id.

   2. Add mount_client.

      Note: mount_client will need to be either 3 or a number > 250.

      cd ~/community
      nano hetzner_nfs.yml
      

      hetzner_nfs:
        vlan_id: 4001
        mount_client: 3

2. Run Ansible role to configure the NFS client.

   sudo ansible-playbook community.yml --tags hetzner_nfs_client_mount
   

Uninstall

Simply run the following commands on their respective servers:

NFS Server (Feederbox)

sudo ansible-playbook community.yml --tags hetzner_nfs_server_uninstall

NFS Client (Mediabox)

sudo ansible-playbook community.yml --tags hetzner_nfs_client_unmount
