I have installed cinder in multiple servers and want to access their space as a unified whole. How is that possible?

For example if I have two 1 TB servers (totalling 2 TB space). I want to use, say, a 1.5 TB chunk of storage through a cinder volume. Please give me some pointers about how to proceed.

You may use gluster as cinder backend.
First . Risky approach

A Striped Volume takes this one step further than the Distributed Volume: In the background, GlusterFS splits up each file delivered to it and distributes the pieces randomly over the individual bricks. This allows for very fast read and write speeds, but again, if even one server fails, all of the data is lost. Therefore, volumes of this kind are only suitable for large, temporary files. To create them a Striped Volume, enter:

 #   gluster volume create examplevolume stripe 3 transport tcp \

Second. Creating Striped Replicated Volumes
