The support is merged in Cinder for active/active, but the hold up now has been
getting Cinder driver maintainers to certify their drivers and storage devices
will work correctly when running in that configuration.

I seem to recall some work being done with the Ceph/RBD driver, but I don't
believe anything has merged for any drivers to enable that.
