Chapter 2. Deploying OpenShift Data Foundation on single node OpenShift clusters using OpenShift Web Console

Procedure

1. Log in to the OpenShift Web Console.
2. Click Operators OperatorHub.
3. Scroll or type ODF LVM Operator into the Filter by keyword box to find the ODF LVM Operator.
4. Click Install.

5. Set the following options on the Install Operator page:

   1. Update Channel as stable-4.11.
   2. Installation Mode as A specific namespace on the cluster.
   3. Installed Namespace as Operator recommended namespace openshift-storage. If Namespace openshift-storage does not exist, it is created during the operator installation.

   4. Select Approval Strategy as Automatic or Manual.

      If you select Automatic updates, then the Operator Lifecycle Manager (OLM) automatically upgrades the running instance of your Operator without any intervention.

      If you select Manual updates, then the OLM creates an update request. As a cluster administrator, you must then manually approve that update request to update the Operator to a newer version.

   5. Click Install.

Procedure

1. In the OpenShift Web Console, click Operators Installed Operators to view all the installed operators.

   Ensure that the Project selected is openshift-storage.

2. Click on the ODF LVM operator, and then click Create instance under LVMCluster.
3. In the Create LVMCluster page, select either Form view or YAML view.
4. Enter a name for the cluster.
5. Click Create.

Verification Steps

1. Click Storage Storage Classes from the left pane of the OpenShift Web Console.
2. Verify that the odf-lvm-<device-class-name> storage class is created with the ODF LVM cluster creation. By default, vg1 is the device-class-name.

Procedure

1. Select the project openshift-storage.

   $ oc project openshift-storage

   Copy to Clipboard Toggle word wrap

2. Display the pods.

   $ oc get pods
   NAME                                               READY   STATUS    RESTARTS      AGE
   lvm-operator-controller-manager-54df65b5c4-n7bhb   3/3     Running   1 (45h ago)   7d2h
   topolvm-controller-645cb47cd4-kskqb                5/5     Running   5 (45h ago)   7d3h
   topolvm-node-7bqxp                                 4/4     Running   0             7d3h
   vg-manager-hwmg2                                   1/1     Running   0             7d

3. Display the lvmcluster.

   $ oc get lvmcluster
   NAME             AGE
   odf-lvmcluster   7d3h

   Copy to Clipboard Toggle word wrap

4. Delete the lvmcluster.

   $ oc delete lvmcluster odf-lvmcluster
   lvmcluster.lvm.topolvm.io "odf-lvmcluster" deleted

   Copy to Clipboard Toggle word wrap

5. Verify the deletion by displaying the lvmcluster.

   $ oc get lvmcluster
   No resources found in openshift-storage namespace.

6. Wait until there is only the lvm-operator pod running.

   $ oc get pods
   NAME                                               READY   STATUS    RESTARTS      AGE
   lvm-operator-controller-manager-54df65b5c4-n7bhb   3/3     Running   1 (45h ago)   7d2h

   Copy to Clipboard Toggle word wrap

7. Change the project to default.

   $ oc project default

   Copy to Clipboard Toggle word wrap

8. Delete the project openshift-storage.

   $ oc delete project openshift-storage
