Encrypted Btrfs storage setup and maintenance guide

Initial setup with LUKS/dm-crypt

This exemplary initial setup uses two devices /dev/sdb and /dev/sdc but can be applied to any amount of devices by following the steps with additional devices.

Create keyfile:

dd bs=64 count=1 if=/dev/urandom of=/etc/cryptkey iflag=fullblock
chmod 600 /etc/cryptkey

upstream plex-upstream {
	# change plex-server.example.com:32400 to the hostname:port of your plex server.
	# this can be "localhost:32400", for instance, if Plex is running on the same server as nginx.
	server plex-server.example.com:32400;
}

The specificity of my setup, is that the Raspberry won’t be a router but a bridge. DHCP is thus delegated to the main ADSL router and all devices connected to the AP will appear on the same network than other devices. The instructions below are based on a fresh Raspbian lite install so that it can be reproduced easily.

Install the required packages :

$ sudo apt-get install -y bridge-utils hostapd

To create a bridge, we need to enable ip_forward in the kernel, for that, edit /etc/sysctl.conf and remove comment (#) from the following line :
