There's differing opinions of BTRFS's suitability in production - it's the default filesystem of SUSE on one hand, on the other RedHat has deprecated BTRFS support because they see it as not being production ready and they don't see it being production ready in the near future. They also feel that the more legacy linux filesystems have added features to compete.

Check what features of BTRFS SUSE actually uses and considers supported/supportable.

It's also the default file system of millions of Synology NASes running in consumer hands (although Synology shimmed on their own RAID5/6 support)

  Kroger (and their subsidiaries like QFC, Fred Meyer, Fry's Marketplace, etc), Walmart, Safeway (and Albertsons/Randalls) all use Suse with BTRFS for their point of sale systems.

  Synology uses standard linux md (for btrfs too). Even SHR (Synology Hybrid RAID) is just different partitions on the drive allocated to different volumes, so you can use mixed-capacity drives effectively.

    Right, instead of BTRFS RAID5/6, they use Linux md raid, but I believe they have custom patches to BTRFS to "punch through" information from md, so that when BTRFS has a checksum mismatch it can use the md raid mirror disk for repair.

  But then, your personal requirements/use cases might not be the same as Facebook's. (And this does not only apply to Btrfs[1]/ZFS, it also applies to GlusterFS, use of specific hardware, ...) [1] which I used for nearly two years on a small desktop machine on a daily basis; ended up with (minor?) errors on the file system that could not be repaired and decided to switch to ZFS. No regrets, nor similar errors since.
