Because this infrastructures supports multiple departments, there are several volume backends. The default volume backends for persistent volume and ephemeral instances are not the fastest. To use volume types available to you, can do:
$openstack volume type list
+--------------------------------------+-----------+-----------+
| ID | Name | Is Public |
+--------------------------------------+-----------+-----------+
| dea91be1-971b-44d6-91dc-f9a6e91c7634 | ecs-ceph | False |
When you create a volume,
From the commandline add the following option to specify the volume backend you want:
'--type ecs-ceph'
From the dashboard gui, when creating a volume there is a ‘ volume type ‘ drop down box to select the type you have access to.
A sample heat resource that specifies a volume type:
sandbox_volume:
type: OS::Cinder::Volume
properties:
image: gt-rhel7server
name: arenarium
size: 20
volume_type: ecs-ceph
