I have a system booting from an BTRFS RAID1, which mounts a data disk during boot formatted as a BTRFS RAID5.
This worked until the most recent kernel update. Since then, I can't mount the data disk anymore during boot.
So what I do, is to deactivate in fstab the mount of the data disk, then reboot (now it boots without problems), then I go into fstab again, activate the data disk and then do a 'mount -a' and everything mounts and works.
So the same configuration that during boot can't mount, mounts, once booted, without a problem.
Here's my fstab:
