The section about the chunk size does not seem to be correct. When creating a btrfs filesystem I can see that 2 GB are allocated. That would indicate that a 1 GB chunk for data and a 1 GB chunk for metadata are created.

Are these 256 MiB still valid?

Yes it is valid, it depends on the filesystem size, 50GiB: --Kdave (talk) 10:07, 4 November 2021 (UTC)
