Diagnosis

Scaling storage
Depending on the type of cluster, you need to add storage devices, nodes, or both.

For more information, see the Scaling storage guide.

Mitigation

Deleting information
If it is not possible to scale up the cluster, you need to delete information in order to free up some space.
