I’ve always wondered, given the warnings in documentation, if there are any people brave enough to try Btrfs in a RAID5/6 configuration. Has anyone here actually tried it with “real” data?

it’s still unstable and shouldn’t be used for anything except testing
Given how flexible RAID1 in btrfs is, I don’t really see any benefit in using RAID5/6.
Some people in the comments of this claims to use it with real data https://www.phoronix.com/news/Linux-6.2-Btrfs-EXT4
If you use it don’t forget to use RAID1 for metadata
If the people on Phoronix are to be believed, it’s a buggy mess that will eat your data. Either way I would recommend using LVMRAID (as it’s much more mature) and putting BTRFS on top. Then you can put DM-Crypt between them and get easy FDE.
If the devs say “unstable”, it’s probably unstable.
