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

Warning - use at your own risk

Remove SentinelOne agent from Mac

Boot into Recovery Mode by holding Cmd+R during reboot
Open Terminal from top menubar
Run /Applications/Utilities/Disk\ Utility.app/Contents/MacOS/Disk\ Utility to open Disk Utility
If your startup disk is encrypted, use Disk Utility to mount it
In Terminal, run chroot /Volumes/Macintosh\ HD
Execute the deletion commands or script

USE AT OWN RISK

This was only tested on a 'partial' SentinelOne installation on the High Sierra beta, where SentinelOne was never allowed to enable it's kernel extension. (Some things failed while I was messing around with OS betas.)

This script is most likely outdated.

A lot happens in 2+ years, at this point there's a good chance this script will do more harm than good. Read the comments before using!

Disclaimer

I take no responsability for any problems a user might have on following this gist. This includes university problems.

The motivation for this is to document, as dummy-oriented as possible, a way to setup and add a system call to Minix OS. This is a classic assignment at Operational Systems classes (and is pretty cool tbh)

Configuration:

ISO used: minix_R3.3.0-588a35b.iso
