Chapter 7. Checking for Local Storage Operator deployments

Red Hat OpenShift Data Foundation clusters with Local Storage Operator are deployed using local storage devices. To find out if your existing cluster with OpenShift Data Foundation was deployed using local storage devices, use the following procedure:

Prerequisites

  • OpenShift Data Foundation is installed and running in the openshift-storage namespace.

Procedure

By checking the storage class associated with your OpenShift Data Foundation cluster’s persistent volume claims (PVCs), you can tell if your cluster was deployed using local storage devices.

  1. Check the storage class associated with OpenShift Data Foundation cluster’s PVCs with the following command: 

    $ oc get pvc -n openshift-storage

  2. Check the output. For clusters with Local Storage Operator, the PVCs associated with ocs-deviceset use the storage class localblock. The output looks similar to the following: 

    NAME                      STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS                  AGE
