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?

      Yes, as in, there were people using Btrfs RAID 5/6. It didn’t end well. Not that I’ve used it - I very much prefer having my data safe.

      The warnings in the docs are there for a reason - those modes of Btrfs simply aren’t finished and thus aren’t fit to be used.

      You can test this yourself easily in a VM, this will let you see how things fail for Btrfs 5/6 when one of the disks “fails”.
