Chapter 4. Managing cluster PVC size
4.1. Configuring the default PVC size for your cluster
To configure how resources are claimed within your OpenShift AI cluster, you can change the default size of the cluster’s persistent volume claim (PVC) ensuring that the storage requested matches your common storage workflow. PVCs are requests for resources in your cluster and also act as claim checks to the resource.
Prerequisites
- You have logged in to OpenShift AI as a user with OpenShift AI administrator privileges.
Changing the PVC setting restarts the workbench pod and makes it unavailable for up to 30 seconds. As a workaround, it is recommended that you perform this action outside of your organization’s typical working day.
Procedure
-
From the OpenShift AI dashboard, click Settings
Cluster settings. - Under PVC size, enter a new size in gibibytes or mebibytes.
- Click Save changes.
Verification
- New PVCs are created with the default storage size that you configured.
4.2. Restoring the default PVC size for your cluster
To change the size of resources utilized within your OpenShift AI cluster, you can restore the default size of your cluster’s persistent volume claim (PVC).
Prerequisites
- You have logged in to OpenShift AI as a user with OpenShift AI administrator privileges.
Procedure
-
From the OpenShift AI dashboard, click Settings
Cluster settings. - Click Restore Default to restore the default PVC size of 20GiB.
- Click Save changes.
Verification
- New PVCs are created with the default storage size of 20 GiB.
