Expanding encrypted Btrfs storage by adding an extra partition
What am I talking about? I’m assuming the following: You have a Btrfs partition that you store data on. (I don’t care what data. Don’t tell me.) You use LUKS to encrypt it. You’re running out of space. You have a way of obtaining additional space on your disk but you can’t just simply expand the existing partition. If your situation differs, the rest of this post may be much less helpful.
