Does Daos have a plan to support disk expansion without restart？

Lombardi, Johann #1469 Hi Qiu, We currently don’t support adding new SSDs to an existing storage node. Assuming that you have spare DIMM slots, SCM can be expanded if you take the engine offline and do a dump/restore of the SCM content. This cannot be done online/in-place.

I mean yea, add new SSDs to an existing storage node. Adding SSDs is more economical than a new storage node so that it may be more common. By the way, is there any way to expand SCM on the existing storage node?
