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.
Reminds me of a time I ended up getting some corruption in some cache file for firefox. It was after I did a number of forced power offs. I’m not sure if I should blame such corruption on the filesysten.
RAID5/6 are clearly marked as unstable in the docs, so that doesn’t bother me too much. But there is definitely a history of corruption. I can’t actually find any concrete info these days as the act seems to have been cleaned up recently. For example Red Hat started supporting BTRFS but dropped official support: https://archive.is/1VuTK

Better hope it was cosmic radiation and not an early indicator of failing hardware.

I think the upcoming on-disk format changes are going to fix most of the RAID5/6 issues.
