RAID1 has been fine for years, but hardly anyone is running that and RAID5/6 are still considered unstable even by the devs: https://btrfs.readthedocs.io/en/latest/Status.html#block-gro...

I ran into Btrfs RAID6 corruption myself about ten years ago. Though to btrfs's credit, I didn't lose any data: the filesystem only locked up read-only on me. But this time I'll take their word on unstable.

> RAID1 has been fine for years

It's never been RAID1 it's the odness of the pid decides which disk to read from.

There is a patch for this. Hopefully it will be available in mainline kernels soon. https://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux....
