BTRFS dropped by RedHat

[Przemek Klosowski <przemek.klosowski@xxxxxxxx>]

The release notes for RHEL 7.4 announce that RedHat gave up on btrfs:

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/7.4_Release_Notes/chap-Red_Hat_Enterprise_Linux-7.4_Release_Notes-Deprecated_Functionality.html

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.

I think RH roadmap is to use XFS over LVM.

This is a pity---BTRFS features looked attractive:

- integrated RAID that ties low level (block/stripe) issues with high-level objects (files); I thought this is important because with brfs filesystem integrity features filesystem-level trouble could be tied to low level issues like silent failures on one raid element. This is important and unique: I had seen failures of large volumes both on proprietary RAID hardware and in software RAID, due to silent corruption of one element of the array, that propagated to other healthy elements.

- snapshotting/rollbacks that enable recovery system update failures and other nice functionality

- scalable support for really large file systems (reasonable fsck times, etc)

Are people who care about mass storage issues aware of RedHat's plans and are OK with the situation? Are there any other options apart from what RedHat is planning?
