Uninstallation

To prevent SUSE Storage from being accidentally uninstalled (which leads to data lost), there is a new setting, deleting-confirmation-flag. If this flag is false, the uninstallation job will fail. Set this flag to true to allow uninstallation. You can set this flag using setting page in the SUSE Storage UI or kubectl -n longhorn-system patch -p '{"value": "true"}' --type=merge lhs deleting-confirmation-flag.

To prevent damage to the Kubernetes cluster, it is recommended to delete all Kubernetes workloads using SUSE Storage volumes (PersistentVolume, PersistentVolumeClaim, StorageClass, Deployment, StatefulSet, DaemonSet, etc).
