## Nova Compute Instance Storage
Nova Compute requires a place to store instances locally. Each node labeled `openstack-compute-node` needs to have the following directory:
```
admin@kubenode01:~$ mkdir -p /var/lib/nova/instances
```
*Repeat this step for each node labeled: `openstack-compute-node`*

Most commonly, we want to validate that Ceph is working correctly. This can be done with the following ceph command: Most commonly, we want to validate that Ceph is working correctly. This can be done with the following ceph command:

Use one of your Ceph Monitors to check the status of the cluster. A couple of things to note above; our health is 'HEALTH_OK', we have 3 mons, we've established a quorum, and we can see that our active mds is 'ceph-mds-2810413505-gtjgv'. We have a healthy environment, and are ready to install our next chart, MariaDB. Use one of your Ceph Monitors to check the status of the cluster.

For Glance and Cinder to operate, you will need to create some storage pools for these systems. Additionally, Nova can be configured to use a pool as well, but this is off by default.
```
kubectl exec -n ceph -it ceph-mon-0 ceph osd pool create volumes 128
kubectl exec -n ceph -it ceph-mon-0 ceph osd pool create images 128
```
Nova storage would be added like this:
```
kubectl exec -n ceph -it ceph-mon-0 ceph osd pool create vms 128
```
The choosing the amount of storage is up to you and can be changed by replacing the 128 to meet your needs.
We are now ready to install our next chart, MariaDB.
