# The kafka chart sets deleteClaim: false on both node pools, so deleting a
# Kafka app leaves its broker and controller PVCs behind on purpose. The e2e
# suite has to delete them itself, after the app is gone (a mounted PVC cannot
# finish deleting), or every later suite in the sandbox runs short of LINSTOR
# space. These tests read hack/e2e-chainsaw/kafka/chainsaw-test.yaml, because
# running it needs a cluster.
