Here's a quick video on how to add volumes to Openstack:

openstack_add_volume.mp4Adding a volume to Openstack - Demo

GlusterFS setup

Once you have your infrastructure running and your RAW volumes mounted to your kubernetes nodes, deploy your Heketi / GlusterFS infrastructure. You can use the scripts included in OOM to automate this in your lab. (Not recommended for production install).

...

Grab the OOM artifacts from Gerrit (we did this on the Rancher master node in our deployment).

Currently the scripts are available by cherry-picking the following changeset: https://gerrit.onap.org/r/#/c/67049/

e.g. Run this after downloading Cassandra OOM: 
git fetch https://gerrit.onap.org/r/oom refs/changes/49/67049/1 && git cherry-pick FETCH_HEAD

git clone http://gerrit.onap.org/r/oom
#git fetch https://gerrit.onap.org/r/oom refs/changes/49/67049/1 && git cherry-pick FETCH_HEAD
cd oom/kubernetes
cd onapcontrib/resources/scripts
ls -l

Validation

Once the script is finished, check to make sure you have a valid StorageClass defined, and GlusterFS/Heketi Pods running on each Kubernetes node:
