Summary

  • Adds an OpenShift CSI extended test that verifies a pod can be deleted after its CSI volume mount was force-unmounted on the node (migrated from openshift-tests-private OCP-66187).
  • The test is opt-in per driver via the OCP manifest (TEST_OCP_CSI_DRIVER_FILES), not the upstream manifest.yaml.
  • OpenShift-only capabilities are merged into upstream DriverInfo.Capabilities at load time so upstream manifests stay free of OCP-specific flags.

Related PR:

Driver enablement should go in csi-operator ocp-manifest.yaml:

openshift/csi-operator#596

Test plan

  • make openshift-tests
  • Dry-run: ./openshift-tests run openshift/csi --dry-run | grep 'Pod delete after umount'
  • Run with OCP manifest containing podDeleteAfterUmount: true (e.g. Azure Disk, Azure File)

Summary by CodeRabbit

  • New Features
    • Added an optional CSI storage test that verifies pods can be deleted successfully after a host-side volume unmount.
    • The test provisions and mounts a volume, validates unmount behavior, and confirms successful cleanup.
    • CSI driver capabilities can now be configured and merged with supported test definitions.
  • Documentation
    • Documented the capability and configuration required to enable this verification.
    • The test remains disabled unless explicitly supported and enabled.

Summary

  • Add CSI suite OpenShift CSI extended - Pod delete after umount (migrated from openshift tests private OCP-66187).
  • Register via RegisterAlwaysOnCSISuites so it runs for all CSI drivers in openshift/csi.

Test plan

  • make openshift-tests
  • Dry-run: ./openshift-tests run openshift/csi --dry-run | grep 'Pod delete after umount'
  • Run against at least one driver (GCP PD)

Walkthrough

Adds OpenShift CSI capability overrides and a test suite that force-unmounts a CSI volume on the host, removes its directory, and verifies pod deletion.

Changes

CSI pod deletion validation

Layer / File(s) Summary
Capability manifest wiring
test/extended/storage/csi/csi.go, pkg/clioptions/clusterdiscovery/csi.go, test/extended/storage/csi/README.md
Adds OpenShift capability overrides and merges them into matching upstream CSI manifests before registration. The documentation describes the capability and merge behavior.
Pod-delete-after-unmount test
test/extended/storage/csi/pod_delete_after_umount.go
Adds a capability-gated suite that provisions a filesystem volume, verifies its CSI mount, force-unmounts it on the host, removes the volume directory, and validates pod deletion.
Suite registration
test/extended/storage/csi/csi.go
Registers the pod-delete-after-unmount suite with the always-on CSI suites.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Mergeability Score: 🔵 Low · up to f6bf9

The test setup may leave generated driver manifests behind when temporary-file cleanup fails, without surfacing the failure. The change is otherwise mergeable with explicit owner follow-up to propagate cleanup errors.

Caution

Pre-merge checks failed

Please resolve all errors before merging. Addressing warnings is optional.

  • Ignore

❌ Failed checks (1 error, 1 warning, 1 inconclusive)

Check name Status Explanation Resolution
Container-Privileges ❌ Error The new suite calls NewHostExec; its pod builder sets hostNetwork=true and SecurityContext.Privileged=true, introducing privileged host access when this test runs. Avoid activating a privileged, host-networked host-exec pod, or use a narrowly scoped alternative with explicit security justification and isolation.
Docstring Coverage ⚠️ Warning Docstring coverage is 62.50% which is insufficient. The required threshold is 80.00%. Write docstrings for the functions missing them to satisfy the coverage threshold.
No-Sensitive-Data-In-Logs ❓ Inconclusive The working tree has no diff, so pull-request causality is not yet established. Provide the pull-request base or a usable diff for the changed files.
✅ Passed checks (12 passed)
Check name Status Explanation
Linked Issues check ✅ Passed Check skipped because no linked issues were found for this pull request.
Out of Scope Changes check ✅ Passed Check skipped because no linked issues were found for this pull request.
Stable And Deterministic Test Names ✅ Passed The PR adds one Ginkgo test with the static title "should delete pod after volume directory was umounted on the node"; no generated names, nodes, namespaces, timestamps, or IDs appear in its title.
Test Structure And Quality ✅ Passed The new It block has one focused outcome, cleans pods, volumes, and host-exec resources, uses bounded storage/pod waits with context, and gives meaningful error messages.
Microshift Test Compatibility ✅ Passed The new Ginkgo test uses core Kubernetes PVC, Pod, and Node APIs plus standard CSI host execution; scans found no unavailable OpenShift APIs, namespaces, or multi-node assumptions.
Single Node Openshift (Sno) Test Compatibility ✅ Passed The new test uses one workload pod and host-exec pod on that pod's node; the diff adds no anti-affinity, spreading, replicas, failover, drain, or cross-node requirement.
Topology-Aware Scheduling Compatibility ✅ Passed The diff adds CSI test logic, capability merging, registration, and documentation only. It adds no deployment/controller scheduling constraints or topology-dependent fields.
Ote Binary Stdout Contract ✅ Passed The PR adds no process-level stdout writes. New writes target a temp file, and the existing fmt.Printf in InitCSITests is unchanged; test output remains inside g.It.
Ipv6 And Disconnected Network Test Compatibility ✅ Passed The added Ginkgo test uses cluster APIs, node host commands, and a configurable test-image helper; it adds no IPv4 literals, IP parsing, URL construction, DNS, or public-service calls.
No-Weak-Crypto ✅ Passed The parent-to-HEAD diff adds CSI test and manifest capability wiring only; it introduces no MD5, SHA1, DES, RC4, Blowfish, ECB, custom crypto, or secret comparisons.
Description Check ✅ Passed Check skipped - CodeRabbit’s high-level summary is enabled.
Title check ✅ Passed The title clearly and concisely describes the added CSI test for pod deletion after host unmount of a mounted volume.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Use a forced unmount for this test scenario.

Line 98 uses normal umount. The suite contract requires validation after a force-unmount. This command can test a different cleanup path and leave the intended regression untested. Add -f.

Proposed fix
- err = hostExec.IssueCommand(ctx, fmt.Sprintf("umount %q && rmdir %q", mountPath, mountPath), node)
+ err = hostExec.IssueCommand(ctx, fmt.Sprintf("umount -f %q && rmdir %q", mountPath, mountPath), node)

Handle temporary-file cleanup errors.

Line 155, Line 165, Line 166, and Line 170 discard errors from os.Remove or Close. A failed cleanup can leave generated manifests in the driver-manifest directory without reporting the failure.

Change the cleanup function to return an error. Propagate cleanup failures from AddDriverDefinition while preserving an external.AddDriverDefinition failure when both operations fail.
