Chen Liang commented on HDFS-11138:
-----------------------------------

I actually do not have any strong opinion on this, if it is making more sense 
to require setting force flag all the time, then I can just make this change. 

Thanks for the suggestion.

> This JIRA adds the skeleton for server side code, which is one of the core 
> components in block storage. For performance concerns, the server does not 
> handle any actual read/write operation but serving primarily as a meta data 
> server. It provides four APIs:
> # create volume : which will call into underlying container layer to allocate 
> containers
> # delete volume : delete a specific volume (as well as its containers)
> # info volume : return information of a specific volume
> # list volume : list all volumes
> Note that this is still subject to potentially major changes. Features such 
> as persistence are missing.
