Btrfs has been deprecated
The Btrfs file system has been in Technology Preview state since the initial release of Red Hat Enterprise Linux 6. Red Hat will not be moving Btrfs to a fully supported feature and it will be removed in a future major release of Red Hat Enterprise Linux.
The Btrfs file system did receive numerous updates from the upstream in Red Hat Enterprise Linux 7.4 and will remain available in the Red Hat Enterprise Linux 7 series. However, this is the last planned update to this feature.
Red Hat will continue to invest in future technologies to address the use cases of our customers, specifically those related to snapshots, compression, NVRAM, and ease of use. We encourage feedback through your Red Hat representative on features and requirements you have for file systems and storage technology.

Hi, I don't know the answer to your question. But maybe Red Hat decided to spend more time in the development of ZFS on Linux. I would appreciate it to get ZFS in an upcoming version of RHEL.
To paraphrase the upstream opinion, btrfs has been "almost production ready" for many years now, but never quite got to the stage where it actually was ready.
In the meantime, many of the features that btrfs provides are now available via other more mature and stable storage technologies like ext4, XFS, LVM, etc. We've put considerable effort into improving these technologies to the point where current Red Hat offerings already cover almost the entire btrfs feature set.
If you have a specific need which btrfs meets but you believe the Red Hat storage offering doesn't meet, then as the docs say, get in touch. I see your account has a Principal Solution Architect assigned to it, they will be glad to hear from you and can discuss implementation with storage/filesytem engineering as required.
There is a good thread on this exact topic here:
