Chapter 5. Verifying your OpenShift Container Storage installation for external mode

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

5.1. Verifying the state of the pods

  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 5.1, “Pods corresponding to OpenShift Container Storage components”

  3. Verify that the following pods are in running state:

    Table 5.1. Pods corresponding to OpenShift Container Storage components

    ComponentCorresponding pods

    OpenShift Container Storage Operator

    • ocs-operator-* (1 pod on any worker node)
    • ocs-metrics-exporter-*

    Rook-ceph Operator

    rook-ceph-operator-*

    (1 pod on any worker node)

    Multicloud Object Gateway

    • noobaa-operator-* (1 pod on any worker node)
    • noobaa-core-* (1 pod on any worker node)
    • noobaa-db-pg-* (1 pod on any worker node)
    • noobaa-endpoint-* (1 pod on any worker node)

    CSI

    • cephfs

      • csi-cephfsplugin-* (1 pod on each worker node)
      • csi-cephfsplugin-provisioner-* (2 pods distributed across worker nodes)
    Note

    If an MDS is not deployed in the external cluster, the csi-cephfsplugin pods will not be created.

    • rbd

      • csi-rbdplugin-* (1 pod on each worker node)
      • csi-rbdplugin-provisioner-* (2 pods distributed across worker nodes)

5.2. Verifying that the OpenShift Container Storage cluster is healthy

  • Click Storage → Overview from the left pane of the OpenShift Web Console and click Block and File tab.
  • In the Status card, verify that Storage Cluster has a green tick mark.

  • In the Details card, verify that the cluster information is displayed as follows:

    Service Name
    OpenShift Container Storage
    Cluster Name
    ocs-external-storagecluster
    Provider
    VSphere
    Mode
    External
    Version
    ocs-operator-4.8.0

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

5.3. Verifying that the Multicloud Object Gateway is healthy

  • Click Storage → Overview from the left pane of the OpenShift Web Console and click the Object tab.

  • In the Status card, verify that both Object Service and Data Resiliency are in Ready state (green tick).

    Figure 5.1. Health status card in Object Dashboard

    Screenshot of Health card in object service dashboard

  • In the Details card, verify that the MCG information is displayed appropriately as follows:

    Service Name
    OpenShift Container Storage
    System Name

    Multicloud Object Gateway

    RADOS Object Gateway

    Provider
    VSphere
    Version
    ocs-operator-4.8.0
Note

The RADOS Object Gateway is only listed in case RADOS Object Gateway endpoint details were included while deploying OpenShift Container Storage in external mode.

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

5.4. Verifying that the storage classes are created and listed

  • 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-external-storagecluster-ceph-rbd
    • ocs-external-storagecluster-ceph-rgw
    • ocs-external-storagecluster-cephfs
    • openshift-storage.noobaa.io
Note
  • If an MDS is not deployed in the external cluster, ocs-external-storagecluster-cephfs storage class will not be created.
  • If an RGW is not deployed in the external cluster, the ocs-external-storagecluster-ceph-rgw storage class will not be created.

For more information regarding MDS and RGW, see Red Hat Ceph Storage documentation

5.5. Verifying that Ceph cluster is connected

Run the following command to verify if the OpenShift Container Storage cluster is connected to the external Red Hat Ceph Storage cluster. 

$ oc get cephcluster -n openshift-storage
NAME                                      DATADIRHOSTPATH     MONCOUNT    AGE      PHASE       MESSAGE                         HEALTH
ocs-external-storagecluster-cephcluster                                   31m15s   Connected   Cluster connected successfully  HEALTH_OK

5.6. Verifying that storage cluster is ready

Run the following command to verify if the storage cluster is ready and the External option is set to true. 

$ oc get storagecluster -n openshift-storage
NAME                        AGE      PHASE EXTERNAL  CREATED AT              VERSION
ocs-external-storagecluster 31m15s   Ready true      2021-02-29T20:43:04Z    4.8.0
