View cluster health and manage storage classes

Contributors netapp-dbagwell amgrissino

After you add clusters to be managed by Astra Control Center, you can view details about the cluster, such as its location, the worker nodes, persistent volumes, and storage classes. You can also change the default storage class for managed clusters.

View cluster health and details

You can view details about the cluster, such as its location, the worker nodes, persistent volumes, and storage classes.

Steps
  1. In the Astra Control Center UI, select Clusters.

  2. On the Clusters page, select the cluster whose details you want to view.

    Note If a cluster is in removed state yet cluster and network connectivity appears healthy (external attempts to access the cluster using Kubernetes APIs are successful), the kubeconfig you provided to Astra Control might no longer be valid. This can be due to certificate rotation or expiration on the cluster. To correct this issue, update the credentials associated with the cluster in Astra Control using the Astra Control API.
  3. View the information on the Overview, Storage, and Activity tabs to find the information that you’re looking for.

    • Overview: Details about the worker nodes, including their state.

    • Storage: The persistent volumes associated with the compute, including the storage class and state.

    • Activity: Shows the activities related to the cluster.

Note You can also view cluster information starting from the Astra Control Center Dashboard. On the Clusters tab under Resource summary, you can select the managed clusters, which takes you to the Clusters page. After you get to the Clusters page, follow the steps outlined above.

Change the default storage class

You can change the default storage class for a cluster. When Astra Control manages a cluster, it keeps track of the cluster’s default storage class.

Note Do not change the storage class using kubectl commands. Use this procedure instead. Astra Control will revert the changes if made using kubectl.
Steps
  1. In the Astra Control Center web UI, select Clusters.

  2. On the Clusters page, select the cluster that you want to change.

  3. Select the Storage tab.

  4. Select the Storage classes category.

  5. Select the Actions menu for the storage class that you want to set as default.

  6. Select Set as default.
