Interesting read on bcachefs. Thanks for that. I have been keeping an eye on it for a while now but didn't dare to try it out.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Interesting read. My understanding is that BTRFS has had long standing issues with it's parity raid configurations (I.e. Raid5/6). Recently, kernel version 6.2 seems to have added more fixes. I'll stick to the "wait and see" approach for the time being, as Raid1 is sufficient for my home server.
Other than the Raid5/6 issue, I don't know of any other issues with BTRFS losing data. If there are some, I'd love to know.
I think the upcoming on-disk format changes are going to fix most of the RAID5/6 issues.
