Official Title: OpenStack Block Storage Cinder

PTL: Rajat Dhasmana 

Mission Statement: "To implement services and libraries to provide on demand, self-service access to Block Storage resources. Provide Software Defined Block Storage via abstraction and automation on top of various traditional backend block storage devices."

Description
Cinder is a Block Storage service for OpenStack. It's designed to present storage resources to end users that can be consumed by the OpenStack Compute Project (Nova). This is done through the use of either a reference implementation (LVM) or plugin drivers for other storage. The short description of Cinder is that it virtualizes the management of block storage devices and provides end users with a self service API to request and consume those resources without requiring any knowledge of where their storage is actually deployed or on what type of device.

Sample cinder.conf
The cinder.conf.sample is no longer maintained and tested in the source tree. Currently you can obtain a copy by running the command 'tox -e genconfig' in a cloned version of the Cinder project and then look in etc/cinder/ for the cinder.conf.sample file.

The newly generated file will have all options in the Cinder project, driver options included.

Additionally, the generated file is available in the Cinder documentation: https://docs.openstack.org/cinder/latest/configuration/block-storage/samples/cinder.conf.html
