Chapter 3. Deploy using local storage devices

Procedure

1. Log in to the OpenShift Web Console.
2. Click Operators OperatorHub.
3. Type local storage in the Filter by keyword​ box to find the Local Storage Operator from the list of operators and click on it.

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

   1. Update channel as either 4.9 or stable.
   2. Installation mode as A specific namespace on the cluster.
   3. Installed Namespace as Operator recommended namespace openshift-local-storage.
   4. Update approval as Automatic.
5. Click Install.

Procedure

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

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

   1. Update Channel as stable-4.9.
   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. Ensure that the Enable option is selected for the Console plugin.
   6. Click Install.

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 OpenShift Data Foundation operator and then click Create StorageSystem.

3. In the Backing storage page, perform the following:

   1. Select the Create a new StorageClass using the local storage devices option.
   2. Expand Advanced and select Full Deployment for the Deployment type option.

   3. Click Next.

      Note

      You are prompted to install the Local Storage Operator if it is not already installed. Click Install and follows procedure as described in Installing Local Storage Operator.

4. In the Create local volume set page, provide the following information:

   1. Enter a name for the LocalVolumeSet and the StorageClass.

      By default, the local volume set name appears for the storage class name. You can change the name.

   2. Choose one of the following:

      • Disks on all nodes to use the available disks that match the selected filters on all nodes.

      • Disks on selected nodes to use the available disks that match the selected filters only on selected nodes.

        Important

        • The flexible scaling feature is enabled only when the storage cluster that you created with 3 or more nodes are spread across fewer than the minimum requirement of 3 availability zones.

          For information about flexible scaling, see Add capacity using YAML section in Scaling Storage guide.

        • If the nodes selected do not match the OpenShift Data Foundation cluster requirement of an aggregated 30 CPUs and 72 GiB of RAM, a minimal cluster is deployed.

          For minimum starting node requirements, see Resource requirements section in Planning guide.

   3. From the available list of Disk Type, select SSD/NVMe.

   4. Expand the Advanced section and set the following options:

      Volume Mode	Block is selected by default.
      Device Type	Select one or more device type from the dropdown list.
      Disk Size	Set a minimum size of 100GB for the device and maximum available size of the device that needs to be included.
      Maximum Disks Limit	This indicates the maximum number of PVs that can be created on a node. If this field is left empty, then PVs are created for all the available disks on the matching nodes.

   5. Click Next.

      A pop-up to confirm the creation of LocalVolumeSet is displayed.

   6. Click Yes to continue.

5. In the Capacity and nodes page, configure the following:

   1. Available raw capacity is populated with the capacity value based on all the attached disks associated with the storage class. This takes some time to show up. The Selected nodes list shows the nodes based on the storage class.
   2. Click Next.

6. Optional: In the Security and network page, configure the following based on your requirement:

   1. To enable encryption, select Enable data encryption for block and file storage.

   2. Choose one of the following Encryption level:

      • Cluster-wide encryption to encrypt the entire cluster (block and file).
      • StorageClass encryption to create encrypted persistent volume (block only) using encryption enabled storage class.

   3. Select Connect to an external key management service checkbox. This is optional for cluster-wide encryption.

      1. Key Management Service Provider is set to Vault by default.
      2. Enter Vault Service Name, host Address of Vault server ('https://<hostname or ip>''), Port number and Token.

      3. Expand Advanced Settings to enter additional settings and certificate details based on your Vault configuration:

         1. Enter the Key Value secret path in Backend Path that is dedicated and unique to OpenShift Data Foundation.
         2. Optional: Enter TLS Server Name and Vault Enterprise Namespace.
         3. Provide CA Certificate, Client Certificate and Client Private Key by uploading the respective PEM encoded certificate file.
         4. Click Save.
   4. Click Next.

7. In the Review and create page, review the configuration details.

   • To modify any configuration settings, click Back to go back to the previous configuration page.
8. Click Create StorageSystem.
