BTRFS can do that, but RAID 5/6 use is discouraged to say the least.

  Synology seems to use it, doesn't it?

    Synology uses mdadm to create the array, then formats the resultant block device as btrfs. Btrfs's RAID code never touches your data.

      Is the RAID code being worked on or would it be better to just remove that capability from btrfs?
