> ## Upcoming features planned in next two weeks:
>
> - Template support for Volgen. Gluster volume mounts and brick
>    processes loads the xlators and respective options based on the
>    provided Volfile. As of now list of Xlators and its options can be
>    modified by changing the Glusterd2 code and recompiling. With this
>    enhancement, list of Xlators to be loaded in generated volfile can
>    be controlled by adding/removing from a template file. This feature
>    provides flexibility to support different usecases without modifying
>    the Glusterd2 code.(https://github.com/gluster/glusterd2/pull/1229)
> - Making bricks provisioner as plugin: Currently LVM provisioner is
>    used to auto provision the bricks when volume create is requested by
>    specifying size without providing the bricks details. With this
>    enhancement new provisioners can be added easily without affecting
>    the existing ones.(https://github.com/gluster/glusterd2/pull/1256)
> - Newly added bricks were not placed properly when distributed
>    replicate volume was expanded. PR is sent to fix the issue
> - Replace brick - Support for replace brick operation as documented
>    here
>    
> https://github.com/gluster/glusterd2/issues/472#issuecomment-408389266
> - Add Volume capacity information in Volume info - Since Volume
>    capacity is static information which will not change after volume
>    create unless volume is expanded. Enhancement is planned to save the
>    capacity information in volinfo when auto provision volume is
>    created. (https://github.com/gluster/glusterd2/pull/1193)
> - Couple of PRs related to Snapshot feature are under
>    review.(https://github.com/gluster/glusterd2/pull/1228,
>    https://github.com/gluster/glusterd2/pull/1053)
> - Tracing support for Volume and Snapshot operations
>    (https://github.com/gluster/glusterd2/pull/1255 and
>    https://github.com/gluster/glusterd2/pull/1149)
> - Support for Volume profile - This helps users to understand and
>    debug the Gluster Volume. In Glusterd, this feature is supported
>    using `gluster volume profile*`
>    command.(https://github.com/gluster/glusterd2/pull/962)
