Yes, by default DevStack configures cinder with "LVM". But we can customize DevStack to configure cinder with our own backend ("real storage backend").<br>
<br>
Below is the link to the path, enables Automatic Configuration of GlusterFS for Cinder using devstack:<br>
<a href="https://review.openstack.org/#/c/133102/">https://review.openstack.org/#/c/133102/</a><br>
<br>
And also below it the link to Configure CEPH with Cinder using devstack:<br>
<a href="https://review.openstack.org/#/c/65113/">https://review.openstack.org/#/c/65113/</a><br>
<br>
Above two are old way of "real storage" plugin implementation. Sean Dague proposed a new way of devstack plugin implementation. Have a look at below two links:<br>
