Delete Stranded Clusters

Applicable to both Classic and Federated modes

A stranded cluster is a cluster that was previously registered in Portworx Backup but is now inaccessible — for example, because it was deleted outside of Portworx Backup, its kubeconfig expired, or the cluster was decommissioned. Portworx Backup retains the cluster record along with its associated backups and schedules until an administrator explicitly removes it.

Prerequisites

• Ensure that the restores and schedules (backup schedules) are deleted before you delete a cluster.

If you are a default admin user, you can now view the clusters created by the non-admin users along with their username in the Portworx Backup home page:

To view the cluster created by non-admin user:

1. Login and access Portworx Backup home page.

note

As an admin user you will only have partial access for the clusters created by non-admin users.

2. Click Clusters icon in the left navigation pane and scroll to the required cluster based on the OWNER column.

3. Click Vertical ellipsis at the end of the selected cluster row and then select Remove to delete the required cluster:

4. If you are sure that you want to delete the cluster, select Confirm Deletion and click Delete.

Stranded clusters are deleted from the system permanently, releasing the occupied storage resources.

note

• Portworx Backup displays metrics data for the clusters owned by the users of the px-admin-group. The web console provides more structured and secure viewing experience for these users, ensuring they access metrics data relevant to their owned clusters.

• For clusters not owned (non-owned cluster) by the users of px-admin-group group, the metrics data is represented by a placeholder symbol -.
