Run oc apply -f storage-provisioning.yaml to apply the file for all worker nodes.

To verify whether the PVC creation is successful, run oc get pvc -n infoscale-vtas on the bastion node.

To verify whether selector is being used, run oc get statefulset -n <InfoScale namespace> on the bastion node.

Output similar to the following indicates a successful creation of pods.

default   storage-0  1/1     Running    0  22h
default   storage-1  1/1     Running    0  22h
default   storage-2  1/1     Running    0  22h
default   storage-3  1/1     Running    0  22h
default   storage-4  1/1     Running    0  22h

Run oc get po -n infoscale-vtas on the bastion node.

Be ready with the temporary storage path on each node of the cluster. Ensure that you specify this path as excludeDevice while configuring cr.yaml. If you do not specify this path, the temporary storage is consumed. As this storage is not persistent, it might lead to a data loss.

Ensure that you do not power off the Azure RedHat OpenShift (ARO) cluster after provisioning storage.
