The `devicemapper` storage driver is deprecated in favor of `overlay2`, and will be removed in a future release. Users of the `devicemapper` storage driver are recommended to migrate to a different storage driver, such as `overlay2`, which is now the default storage driver. The `devicemapper` storage driver facilitates running Docker on older (3.x) kernels that have no support for other storage drivers (such as overlay2, or AUFS). Now that support for `overlay2` is added to all supported distros (as they are either on kernel 4.x, or have support for multiple lowerdirs backported), there is no reason to continue maintenance of the `devicemapper` storage driver.
