Chapter 4. Verifying OpenShift Container Storage deployment

Use this section to verify that OpenShift Container Storage is deployed correctly.

4.1. Verifying the state of the pods

To verify that the pods of OpenShift Containers Storage are in running state, follow the below procedure:

Procedure

  1. Log in to OpenShift Web Console.
  2. Click Workloads → Pods from the left pane of the OpenShift Web Console.
  3. Select openshift-storage from the Project drop down list.

    For more information on the expected number of pods for each component and how it varies depending on the number of nodes, see Table 4.1, “Pods corresponding to OpenShift Container storage cluster”.

  4. Click on the Running and Completed tabs to verify that the pods are running and in a completed state:

4.2. Verifying the OpenShift Container Storage cluster is healthy

To verify that the cluster of OpenShift Container Storage is healthy, follow the steps in the procedure.

Procedure

  1. Click Storage → Overview and click the Block and File tab.
  2. In the Status card, verify that Storage Cluster and Data Resiliency has a green tick mark.
  3. In the Details card, verify that the cluster information is displayed.

For more information on the health of the OpenShift Container Storage clusters using the Block and File dashboard, see Monitoring OpenShift Container Storage.

4.3. Verifying the Multicloud Object Gateway is healthy

To verify that the OpenShift Container Storage Multicloud Object Gateway is healthy, follow the steps in the procedure.

Procedure

  1. Click Storage → Overview from the OpenShift Web Console and click the Object tab.
  2. In the Status card, verify that both Object Service and Data Resiliency are in Ready state (green tick).
  3. In the Details card, verify that the Multicloud Object Gateway information is displayed.

For more information on the health of the OpenShift Container Storage cluster using the object service dashboard, see Monitoring OpenShift Container Storage.

4.4. Verifying that the OpenShift Container Storage specific storage classes exist

To verify the storage classes exists in the cluster, follow the steps in the procedure.

Procedure

  1. Click Storage → Storage Classes from the OpenShift Web Console.
  2. Verify that the following storage classes are created with the OpenShift Container Storage cluster creation:
