NAS

The NAS is relied upon for many other hosts on the network, which need to be offlined before the NAS can be shut down.

1. Offline the seedbox. Follow the graceful reboot instructions described in its note to shut it down.
2. Offline the server. Follow the graceful reboot instructions described in its note to shut it down.
3. Offline the NAS. SSH into the NAS and run shutdown now.
4. Perform necessary maintenance, then reboot the NAS.

Seedbox

1. Stop all Docker containers with docker stop $(docker ps -aq).
2. Reboot the host with sudo reboot now.
3. When the host has finished booting, re-mount all NAS shares defined in /etc/fstab with sudo mount -a.
4. Start all Docker containers with docker start $(docker ps -aq).

Server

1. Stop all Docker containers with docker stop $(docker ps -aq).
2. Reboot the host with sudo reboot now.
3. When the host has finished booting, re-mount the NAS SMB shares defined in /etc/fstab with sudo mount -a
4. Start all Docker containers with docker start $(docker ps -aq).

Router

The router is relied upon by all clients on the network, so they all need to be offlined or prepared.

1. Offline the seedbox.
2. Offline the server.
3. Offline the NAS.
4. Run shutdown.

PiHole

The PiHole is relied upon for DNS resolution for all devices on the network which have not manually configured another DNS resolver.

1. Log into router via SSH and run the following:

configure
delete system name-server 192.168.1.22
set system name-server 1.1.1.1
commit; save; exit

2. Reboot the Pi with sudo reboot now
3. Switch back to the router and run the following:

configure 
delete system name-server 1.1.1.1
set system name-server 192.168.1.22
commit; save; exit

4. Done.
