BTRFS dropped by RedHat

[Przemek Klosowski]

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/...

    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?
