Procedure

  1. In the OpenShift Web Console, click Storage Data Foundation.
  2. Click the Storage Systems tab and then click on ocs-storagecluster-storagesystem.
  3. In the Status card of Block and File dashboard under Overview tab, verify that both Storage Cluster and Data Resiliency has a green tick mark.
  4. In the Details card, verify that the cluster information is displayed.

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

3.3. Verifying the Multicloud Object Gateway is healthy

Procedure

  1. In the OpenShift Web Console, click Storage Data Foundation.

  2. In the Status card of the Overview tab, click Storage System and then click the storage system link from the pop up that appears.

    1. In the Status card of the Object tab, verify that both Object Service and Data Resiliency have a green tick.
    2. In the Details card, verify that the MCG information is displayed.

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

Important

The Multicloud Object Gateway only has a single copy of the database (NooBaa DB). This means if NooBaa DB PVC gets corrupted and we are unable to recover it, can result in total data loss of applicative data residing on the Multicloud Object Gateway. Because of this, Red Hat recommends taking a backup of NooBaa DB PVC regularly. If NooBaa DB fails and cannot be recovered, then you can revert to the latest backed-up version. For instructions on backing up your NooBaa DB, follow the steps in this knowledgabase article.

3.4. Verifying that the specific storage classes exist

Procedure

  1. Click Storage Storage Classes from the left pane of the OpenShift Web Console.

  2. Verify that the following storage classes are created with the OpenShift Data Foundation cluster creation:

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