OCPBUGS-74510: Removed VSphereMultiDisk feature gate

[vr4manta]

OCPBUGS-74510

Changes

• Removed usages of VSphereMultiDisk feature gate
• Updated tests to assume GA of feature gate

Notes

Removed VSphereMultiDisk feature gate now that it has been GA for several releases

Summary by CodeRabbit

• New Features

  • vSphere machines now support multiple data disks by default, without requiring a separate feature toggle.
  • Data disk validation is consistently applied, including size, naming, and provisioning constraints.

• Bug Fixes

  • Removed the previous configuration restriction that blocked additional disks when the feature toggle was disabled.
  • Updated validation and end-to-end coverage to reflect the default multi-disk behavior.

Walkthrough

The VSphereMultiDisk feature gate was removed from registration, defaults, reconciliation, and webhook validation. vSphere data disks are now processed and validated without the gate. Unit and end-to-end tests were updated.

Changes

VSphereMultiDisk gate removal

Layer / File(s)	Summary
Remove gate configuration cmd/machineset/main.go, cmd/vsphere/main.go, pkg/operator/..., pkg/util/testing/testing.go	Command, operator, and test configuration no longer registers or enables VSphereMultiDisk.
Enable unconditional disk processing pkg/controller/vsphere/reconciler.go, pkg/webhooks/machine_webhook.go	Reconciliation and webhook validation no longer require VSphereMultiDisk for vSphere data disks.
Update disk validation coverage pkg/webhooks/machine_webhook_test.go, test/e2e/vsphere/machines.go	Tests no longer configure or require the feature gate. Existing disk validation cases remain covered.

🚥 Pre-merge checks | ✅ 13 | ❌ 2

❌ Failed checks (2 warnings)

Check name	Status	Explanation	Resolution
Test Structure And Quality	⚠️ Warning	test/e2e/vsphere/machines.go creates Machine and MachineSet resources but has no DeferCleanup/AfterEach, and many Expect(err).NotTo(HaveOccurred()) assertions lack messages.	Register deferred cleanup after each resource is created, wait for deletion, and add operation-specific messages to every cluster-operation assertion.
Single Node Openshift (Sno) Test Compatibility	⚠️ Warning	The changed vSphere Describe has no SNO guard, while its tests create/delete machines and scale a MachineSet, which assumes node-scaling support.	Because the test is [Serial], run /payload-job periodic-ci-openshift-release-master-nightly-4.22-e2e-aws-ovn-single-node-serial; add a SNO skip label or runtime guard if unsupported.

✅ Passed checks (13 passed)

Check name	Status	Explanation
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title check	✅ Passed	The title clearly and concisely describes the main change: removing the VSphereMultiDisk feature gate.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
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 changes only a static Ginkgo Describe label; It and Entry titles are static and contain no generated names, timestamps, IPs, namespaces, or other run-dependent values.
Microshift Test Compatibility	✅ Passed	The PR adds no new e2e test logic; it only removes a Describe label. Existing vSphere tests retain [apigroup:machine.openshift.io] tags, which protect them from MicroShift.
Topology-Aware Scheduling Compatibility	✅ Passed	The diff only removes the VSphereMultiDisk gate and updates validation/tests; it adds no affinity, topology spread, node selectors, tolerations, PDBs, or workload replica constraints.
Ote Binary Stdout Contract	✅ Passed	The commit does not alter OTE setup; main calls logs.InitLogs, klog defaults to stderr, and OTE config sets GinkgoWriter to os.Stderr. fmt.Printf sites run from It paths.
Ipv6 And Disconnected Network Test Compatibility	✅ Passed	The only e2e change removes the VSphereMultiDisk label; no new Ginkgo test, IPv4 literal, IPv4-only parsing, public URL, or external connectivity was added.
No-Weak-Crypto	✅ Passed	The PR changes only feature-gate and disk-validation logic; added-line and Go crypto scans found no MD5, SHA1, DES, RC4, Blowfish, ECB, custom crypto, or secret comparisons.
Container-Privileges	✅ Passed	The patch changes only feature-gate and vSphere validation code; it adds or modifies no container or Kubernetes manifest privilege settings.
No-Sensitive-Data-In-Logs	✅ Passed	The patch adds no logging calls or logged values. It only removes the VSphereMultiDisk initialization log; existing data-disk logs are unchanged and contain disk fields, not credentials or tokens.
