I've only used btrfs and devicemapper on el7. btrfs has worked well. devicemapper ate may data on multiple occasions. Is redhat supporting overlay in the el7 kernels now?

This is not recommended for production (see 'docker info'). We've been poking around with docker storage backends in TripleO for almost 2 months now here: https://review.openstack.org/#/c/451916/ For TripleO there are a couple of considerations: - we intend to support in place upgrades from baremetal to containers - when doing in place upgrades re-partitioning disks is hard, if not impossible. This makes using devicemapper hard. - we'd like to to use a docker storage backend that is production ready. - our target OS is latest Centos/RHEL 7 As we approach pike 2 I'm keen to move towards a more production docker storage backend. Is there consensus that 'overlay2' is a reasonable approach to this? Or is it too early to use that with the combinations above? Looking around at what is recommended in other projects it seems to be a mix as well from devicemapper to btrfs.
