▶ chunk
A chunk is simply a piece of storage that Btrfs can use to put data on. Think of a chunk (usually 1GiB) as of a page in a book. The book is the volume, and the chunk is one page of it. When you start, all pages are empty. When you write data to the volume, one page (="chunk") after the other is written to.
