* Extend cinder-volumes past 20GB to allow for creating additional volumes to attach to instances.
** Followed the [https://udaraliyanage.wordpress.com/2014/05/23/openstack-increase-volume-capacity OpenStack Increase Volume Capacity] tutorial
** Created ''/usr/bin/ext-cinder-vol'' script:
::<precode>#!/bin/bash</code>::<code>/usr/sbin/losetup -f /var/lib/cinder/cinder-volumes-ext</code>::<code>/usr/sbin/vgchange --activationmode partial -a y cinder-volumes</code>::<code>/usr/bin/systemctl restart openstack-cinder-volume</code>::<code>/usr/bin/systemctl restart openstack-cinder-api</code>::<code>/usr/bin/systemctl restart openstack-cinder-scheduler</precode>
** Add to root crontab:
::<precode>@reboot /usr/bin/ext-cinder-vol</precode>
** Created 130Gb additional space for volumes (''/mnt/backup/stack-volumes'').
** Total volume space available is now 150GB.
