Hi Ben,
RedHat (which CentOS is based off) have included btrfs in RHEL7 as
Technology Preview. This basically means that they are happy for you to
use it at your own risk. I have spoken with an engineer there and they
said they would basically try to support any related issues using it
that they could, but there was no guarantees with their support.
So seeing as RedHat is targeted at enterprise and they are not
guaranteeing support on it, I would not use it in production unless:
* You have a reliable backup strategy.
* You know the Recovery point objective.
* You know the Mean time to recovery.
* Does the advantages of using btrfs out weigh the possibility for
causing you down time and a lot of work down the track?
The current ceph production recommendation is xfs.
Regards,
Ross

Howdy,
The Ceph docs still say btrfs is 'experimental' in one section, but
say it's the long term ideal for ceph in the later section. Is this
still accurate with Hammer? Is it mature enough on centos 7.1 for
production use?
(kernel is 3.10.0-229.7.2.el7.x86_64 )
thanks-
