All of the "btrfs eats your data" bugs have been fixed and the people who constantly repeat them are people who relied on an experimental filesystem for files they cared not to lose. FUD all around. I have a btrfs on my home file server that's been running just fine for almost 10 years now and has survived the initial underlying hard drives mechanical death. Since then I have used it in plenty of production environments.
Don't do RAID 5. Just don't. That's not just a btrfs shortcoming. I lost a hardware RAID 5 due to "puncture" which would have been fascinating to learn about if it hadn't happened to a production database. It's an academically interesting concept but it is too dangerous especially with how large drives are now, if you're buying three, buy four instead. RAID 10 is much safer especially for software RAID.
Stop parroting lies about btrfs. Since it became marked stable, it has been a reliable, trustworthy, performant filesystem.
But as much as I trust it I also have backups because if you love your data, it's your own fault if you don't back it up and regularly verify the backups.
