Updating the storage quota of a Hosted Control Plane cluster

Update the allotted storage quota of the Fusion Data Foundation client on a Hosted Control Plane cluster to meet the storage requirement of the application workloads.

Before you begin

Points to remember before starting this procedure:
  • You can only increase the storage quota from a defined value to a higher limited value, such as from 90Gi to 100Gi, 100Gi to 200Gi, 9Gi to 1Ti, and so on.
  • You can't increase the storage quota from a defined value to unlimited.
  • You can't decrease the storage quota.
  • You can't modify the storage quota from unlimited to any specific value, as this action is considered a decrease.
  • When you set the storage quota, it sets limits on the total storage consumption across the cluster. Therefore, while updating the storage quota, ensure that:
    • The value meets the storage requirements for all application workloads in the cluster.
    • The value meets the storage requirements of all PersistentVolumeClaims (PVCs), regardless of their state within the cluster.

About this task

Use this procedure if you configured the storage quota for Fusion Data Foundation clients during their installation on hosted clusters and now need to increase it. For more information on storage quota configuration, see Installing Fusion Data Foundation on a Hosted Control Plane cluster.

Whenever the storage consumption of a Fusion Data Foundation client exceeds 80% of its quota limit, you might face issues in creating new applications on the cluster.

You can verify the usage by checking the Storage quota utilization field on the Storage Clients tab in the OpenShift® Container Platform web console.

If the client's storage consumption exceeds 80% of the quota, a warning icon appears next to the value of the Storage quota utilization field along with the StorageQuotaUtilizationThresholdReached alert. In such cases, increase the client's storage quota to clear the alert.

Note: To see the details of the StorageQuotaUtilizationThresholdReached alert, go to Notifications > Other Alerts.

Procedure

  1. Log in to the OpenShift Container Platform web console and select All clusters.
  2. Go to Infrastructure > Clusters.
    The Cluster list tab appears on the screen.
  3. Click the ellipsis menu of the required cluster and select Edit labels.
    The Edit labels window appears on the screen.
  4. Update the isf.ibm.com/fusion-fdf-quota=<value> with the required value.
    Remember: The storage quota value must match the pattern <integar-value><Gi/Ti>, such as 10Gi, 10Ti, or so on. Otherwise, an error message appears on the screen.

    For example:

    Old storage quota value:

    isf.ibm.com/fusion-fdf-quota=100Gi

    New storage quota value:

    isf.ibm.com/fusion-fdf-quota=1Ti
  5. Click Save.
  6. Verify that the Storage Clients tab displays the updated storage quota for the client as follows.
    1. Go to the hub cluster in the OpenShift Container Platform web console.
    2. Select the Storage Clients tab under the Storage menu.
    3. Check whether the Storage quota field displays the updated storage quota and the value of the Storage quota utilization field is below 80%.

Results

The Storage Clients tab displays the updated storage quota for the relevant storage client.
