Move your BTRFS /home subvolume to a new disk

Or in my case, to many disks. I have 4x Samsung 990 Drives that I want to setup in RAID10 with BTRFS and move my /home directory over to these disks. Here are the steps I took to get everything setup and moved over. I went with RAID10 on BTRFS, but you can use this guide to move any subvolume to a new disk, whatever the setup might be.

All of this was done on Fedora 38 workstation. Your millage may vary.

WARNING: BACKUP YOUR DATA BEFORE DOING THIS!

Seriously, back up your data first if you care about it. I use restic and my fancy restic-systemd-units to take incremental backups to my TrueNAS Scale server and to a local secondary hard drive in my workstation. I will probably be moving to incremental local backups with snapper in the future.

This guide allows you to use the TPM on your computer to decrypt your LUKS encrypted volumes. If you are worried about a cold boot attack on your hardware please DO NOT use this guide with your root volume!
