Why is force-deleting a StatefulSet Pod treated as dangerous?

  1. The StatefulSet will not recreate the Pod afterwards
  2. The Pod's PersistentVolumeClaim is deleted with it
  3. A replacement may take the same identity while the old process still runs
  4. The ordinal numbering of the remaining Pods shifts
Show the answer

Answer: C. A replacement may take the same identity while the old process still runs

A force delete does not wait for the node to confirm termination, so the workload may still be running there when a new Pod claims the same name and volume.
