Chapter 2. Verifying OpenShift Container Storage deployment for internal mode

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

2.1. Verifying the state of the pods

To determine if OpenShift Container storage is deployed successfully, you can verify that the pods are in Running state.

Procedure

  1. Click Workloads → Pods from the left pane of the OpenShift Web Console.
  2. 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 2.1, “Pods corresponding to OpenShift Container storage cluster”.

  3. Verify that the following pods are in running and completed state by clicking on the Running and the Completed tabs:

2.2. Verifying the OpenShift Container Storage cluster is healthy

You can verify health of OpenShift Container Storage cluster using the persistent storage dashboard. For more information, see Monitoring OpenShift Container Storage.

  • Click Home → Overview from the left pane of the OpenShift Web Console and click Persistent Storage tab.
  • In the Status card, verify that OCS Cluster has a green tick mark as shown in the following image:

2.3. Verifying the Multicloud Object Gateway is healthy

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

  • Click Home → Overview from the left pane of the OpenShift Web Console and click the Object Service tab.
  • In the Status card, verify that the Multicloud Object Gateway (MCG) storage displays a green tick icon as shown in following image:

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

To verify the storage classes exists in the cluster:

  • Click Storage → Storage Classes from the left pane of the OpenShift Web Console.
  • Verify that the following storage classes are created with the OpenShift Container Storage cluster creation:

    • ocs-storagecluster-ceph-rbd
    • ocs-storagecluster-cephfs
    • openshift-storage.noobaa.io
    • ocs-storagecluster-ceph-rgw
