Restore from backup. No point in trying to figure out what changed, how and where.

If you have a look at the btrfs mailing lists post that introduced RAID1c34, they were created because RAID56 were not considered viable or fixable. It’s in couched language but reasonably clear. I don’t think you’re thinking of using those (RAID56) but don’t.

Never had any btrfs problems that weren’t self generated or date from a really sticky period in btrfs’s history (years ago, 4.13 or maybe 3.13). I’ve used RAID56 until RAID1c34 became available and RAID10 where I could.

Haven’t tried LUKS - btrfs though, although effectively no worse than putting btrfs in a VM (which is fine if slow at the time), albeit a bit more computationally intensive.

Install your own from one of the parent distros: Debian, Fedora/openSUSE, sources (eg. Exherbo, Gentoo), the state-based one I always forget.
