In this section, we use the Cinder CLI to verify that the configuration presented in the section called “cinder.conf” has been properly initialized by Cinder.

In this section, we create a variety of Cinder Volume Types that leverage both the default capabilities of each driver, as well as the NetApp specific extra specs described in Table 4.11, “NetApp supported Extra Specs for use with Cinder Volume Types”.
- The
iscsitype provisions Cinder volumes onto any backend that uses the iSCSI storage protocol (in this example, that would be[cdot-iscsi]and[eseries-iscsi]). - The
nfstype provisions Cinder volumes onto any backend that uses the NFS storage protocol (in this example, that would be[cdot-nfs]). - The
goldtype provisions Cinder volumes onto any backend that has a SnapMirror relationship (in this example, that would be[cdot-nfs], although only one of the four NFS exports defined in/etc/cinder/nfs_shareshas this support). - The
silvertype provisions Cinder volumes onto any backend that has deduplication enabled (in this example, that would be[cdot-nfs], although only one of the four NFS exports defined in/etc/cinder/nfs_shareshas this support). - The
bronzetype provisions Cinder volumes onto any backend that has compression enabled (in this example, that would be[cdot-nfs], although only one of the four NFS exports defined in/etc/cinder/nfs_shareshas this support). - The
analyticstype provisions Cinder volumes onto the[eseries-iscsi]backend.

We'll now look at the local NFS mounts that are present on the node that is running cinder-volume and look for the volumes that were created on NFS backends. By mapping the mountpoints to the directories where the volume files exist, we are able to associate that the volumes were created in the appropriate FlexVol volume that had the NetApp specific features enabled that matched the Cinder volume type definitions.

In this section, we will configure a Cinder volume type, a Cinder QoS spec, and lastly associate the QoS spec with the volume type.

After we associate the QoS spec with the volume type, we can use the volume type just as we did in the section called “Creating and Defining Cinder Volume Types”. The example below shows how to verify that the QoS policy group has been created on the NetApp storage controller.
qos policy-group show -policy-group *66027b97-11d1-4399-b8c6-031ad8e38da0*
Name Vserver Class Wklds Throughput
---------------- ----------- ------------ ----- ------------
openstack-66027b97-11d1-4399-b8c6-031ad8e38da0
dustins01 user-defined 1 0-100IOPS
The name of the QoS policy group created on the storage controller contains the UUID of the Cinder volume that was created previously. This QoS policy group has been assigned to the file or LUN on the storage controller to ensure an isolated, independent limit is enforced on a per-Cinder-volume basis.
In this section, we will configure a Cinder volume type, associate the volume type with a backend capable of supporting consistency groups, create a Cinder consistency group, create a Cinder volume within the consistency group, take a snapshot of the consistency group, and then finally create a second consistency group from the snapshot of the first consistency group.

To delete a consistency group, first make sure that any snapshots of the consistency group have first been deleted, and that any volumes in the consistency group have been removed via an update command on the consistency group.
$ cinder consisgroup-update cg2 --remove-volumes ddb31a53-6550-410c-ba48-a0a912c8ae95
$ cinder delete ddb31a53-6550-410c-ba48-a0a912c8ae95
Request to delete volume ddb31a53-6550-410c-ba48-a0a912c8ae95 has been accepted.
