You can add clusters to the block storage service to increase storage capacity for volumes.

Prerequisites

Note: If you want to add compute clusters from a separate vCenter Server instance, you must deploy VMware Integrated OpenStack with NSX-T Data Center networking. Other networking modes do not support adding compute clusters from separate vCenter Server instances.

If you have added resources to your vSphere environment after deploying OpenStack, refresh your vCenter Server instance before proceeding.

  1. Log in to the Integrated OpenStack Manager web interface as the admin user.
  2. In OpenStack Deployment, click the name of your deployment and open the Manage tab.
  3. On the Settings tab, click vCenter Credentials.
  4. In the VC Resources column for the desired vCenter Server instance, click Refresh.

Procedure

  1. Log in to the Integrated OpenStack Manager web interface as the admin user.
  2. In OpenStack Deployment, click the name of your deployment and open the Manage tab.
  3. On the Cinder tab, click Add.
  4. From the vCenter Server drop-down menu, select the vCenter Server instance containing the compute cluster that you want to add.
    ( NSX-T Data Center only) If the desired vCenter Server instance is not displayed, click the Add (plus sign) icon and enter its host name and credentials.
  5. Select VMDK or FCD as the back-end driver.
  6. Enter an availability zone for the new cluster.
  7. From the table, select the desired compute cluster.

Results

The capacity of the block storage service increases accordingly with the size of the additional cluster.

What to do next

You can remove clusters from your deployment by selecting the desired cluster and clicking Delete.
