I've mounted a btrfs filesystem on /var/lib/docker, and added "-s btrfs" to /etc/sysconfig/docker. Whenever I try to start docker the logs produce the following message:
driver not supported [8d0e189f] -job initserver() = ERR (1)
Anyone out there with experience using btrfs with docker on a rhel/centos/fedora system. Also, Docker was installed using the epel docker-io.rpm.
docker-io-1.0.0-6.el6.x86_64
It does not work currently. You need to disable SELinux support for docker. See https://github.com/docker/docker/issues/7952
