Reviewed the RDMA fabric wiring on top of #2355. Two findings are blocking:
-
Both new NicClusterPolicy manifests activate
validators/deployment/expected_resources.go'sverifyRDMAFabricReadygate:recipeDeclaresRDMAFabricmatches on the substringnic-cluster-policy(not an AKS-specific marker), and bothnic-cluster-policy-oke-gb200.yamlandnic-cluster-policy-oke-l40s.yamlmatch it. But the gate itself still hardcodeshelper.AKSRdmaSharedResource(rdma/hca_shared_devices_a) as the resource it polls for. Neither OKE manifest advertises that resource — GB200 advertisesnvidia.com/mlnxnicsviardmaSharedDevicePlugin, L40S the same viasriovDevicePlugin. The deployment-phase gate will therefore poll for a resource that never appears and time out on a correctly configured OKE cluster. This needs a provider/policy-aware expected resource (or an OKE-specific resource constant threaded through the same gate), not a rename ofAKSRdmaSharedResource's comment. -
driver.kernelModuleConfig.name: nvidia-kernel-module-params(gb200-oke-training.yaml, added unconditionally under the top-levelgpu-operatorcomponentRef) is rendered, but no GPU Operator driver DaemonSet consumes it or reloads the image-supplied host driver — this PR's base already inheritsdriver.enabled: falsefromvalues-oke.yaml, and this PR is de-stacked from #2355 (that PR'soci-managedprofile corroborates the behavior persists, but isn't the cause here). So this PR cannot applyNVreg_GrdmaPciTopoCheckOverride=1unless the image/bootstrap already sets it, and GPUDirect RDMA over the new IB fabric can silently fall back to Socket rather than DMA-BUF. There's also no OKE-side preflight for this — the existing fail-fast check for a missingNVreg_GrdmaPciTopoCheckOverrideis EKS-only. Either gate this wiring to a driver-enabled configuration and provide a real mechanism for the image-driver case, or extend the preflight to cover OKE and fail closed with remediation.
Two more are worth addressing before or shortly after merge:
-
The incompatibility with Oracle's opt-in
NvidiaNetworkOperatoradd-on is noted in both overlays' componentRef comments and in the PR's rollout notes, but it's absent from product documentation and from runtime validation — nothing in this PR (or #2355) checks whether that add-on is enabled before deploying this component. It's the same ownership-conflict pattern #2355 just built a projection/gate for, though a duplicate operator/controller here is a broader failure mode than duplicate device advertising. Worth the same detection treatment, or at least a documented, tracked follow-up. -
docs/user/validation.mdstill documents "GB200/OKE recipes enable-nvlsonly: OKE NET/RDMA stays out of the support matrix until the OCI testbed proves a non-Socket NCCL transport end to end" (around line 81), and its check-applicability table (~line 54) still listsnccl-all-reduce-bw-netas EKS-only for GB200. This PR doesn't touch that file, so both sections now contradict the shipped code once-netis enabled for gb200-oke-training.
Also blocking, mechanically:
make qualify's yamllint step fails on both new values files:values-oke-gb200.yaml:23andvalues-oke-l40s.yaml:32(comment not indented like content) — flagged inline.- None of the four new component files (
nic-cluster-policy-oke-gb200.yaml,nic-cluster-policy-oke-l40s.yaml,values-oke-gb200.yaml,values-oke-l40s.yaml) carry the repository's Apache license header that every sibling file (e.g.nic-cluster-policy-aks.yaml) has —addlicense -checkwill fail on all four. - Head
6dfb98ais a merge commit ontomainrather than a rebase, and the PR is currently reported behindmain. Per the repo's branch-hygiene rule this needs a rebase, not a merge commit, before it can land.
Requesting changes on the two RDMA/kernel-param blockers plus the mechanical lint/license/rebase items; the add-on conflict detection and stale doc can go in the same pass or as tracked follow-ups.

Thanks for addressing the review findings. The current code changes are substantively approvable, and tracking the NvidiaNetworkOperator conflict in #2522 is an acceptable non-blocking follow-up. Before approval, please rebase onto current main and let the required checks rerun. Please also update the PR description: it still says this PR is stacked on #2355 even though the branch was de-stacked, and it should reflect the final RDMA-resource derivation, the OKE NVreg preflight with both remediation routes, and the #2522 disposition. Once the rebased diff is unchanged in substance, the description is current, and the required checks are green, this is ready for approval. |

Multi-persona review + adversarial meta-review
Method: 4 parallel persona reviewers (Correctness · Domain/Recipe-Architecture · Validator/K8s-Operability · Test-coverage/Supply-chain), then an adversarial senior meta-review that re-derived every finding from the resolved code at 5a81d978.
Legend: 🔴 Blocker · 🟠 Major · 🟡 Minor · 🔵 Nitpick
Prior reviewers (not duplicated): @yuanchen8911 requested changes on an earlier SHA (2 RDMA/kernel blockers + lint/license/rebase) — all addressed in 985f5d3c; @mchmarny approved the older a7d1d23 (noting the branch was behind base); CodeRabbit informational. The Major below is a deeper, still-open facet of @yuanchen8911's blocker #1: the hardcoded AKSRdmaSharedResource mismatch was fixed by the new rdmaFabricResource derivation, but the cohort-label half of that same gate was not surfaced.
Overall assessment
A careful, well-reasoned port that faithfully mirrors the AKS sibling. The heavy lifting — deriving the advertised resource from the manifest (replacing the hardcoded constant), the OKE NET preflight, fail-closed derivation, exemption path-scoping, BOM/golden regen, and the validation.md update — is correct and independently verified. One Major warrants verification before merge; everything else is Minor/Nitpick.
Confirmed non-issues (examined, not defects)
- Preflight correctly reaches OKE —
fabric==fabricEFAdefault →templatePathresolvestestdata/gb200/oke/runtime-net.yaml; grep exit-code direction is fail-closed;/proc/driver/nvidia/paramsstrips theNVreg_prefix (matchingGrdmaPciTopoCheckOverride: 1is correct). rdmaFabricResourcefails closed on 0 / >1 / parse errors;nilDataProvider is the documented embedded-catalog fallback; watch loop, errgroup fan-out, and cleanup-on-background-context are all correct.- kernel-module-params wiring is sound — the ConfigMap renders inert under
oci-managedand is consumed underoperator-managed;preManifestFilesis the right hook; keeping it in the leaf is correct. - Shared
nvidia.com/mlnxnicsacross both plugins is intentional and collision-free (mutually exclusive recipes). - Missing
nodeAffinityon OKE device-plugin DaemonSets — benign placement noise (plugins no-op on non-matching nodes). OracleNvidiaNetworkOperatoradd-on conflict — doc-only + #2522 tracked, acceptable. - Supply-chain/tests: exemption path-scoping genuinely prevents tag-reuse ride-through; BOM 100→104 (+4 L40S images, GB200 reuses the shared image); goldens changed for exactly the 2 OKE leaves; the
validation.mdsections @yuanchen8911 flagged are both updated.
Pre-existing observations (reused preflight code, not changed by this PR — hence in this summary, not inline)
validators/performance/nccl_preflight_nvreg.go's pod-lifecycle code is reused unchanged; this PR extends its applicability to OKE, so these are worth noting even though the lines aren't in the diff:
- 🟡
checkNVregOnNode+waitForPreflightPodPhasehave no unit tests. Only the pureparseNVregFromParamsandgb200NetPreflightAppliesare covered; the PodFailed-vs-infra classification and watch channel-close re-Get are untested. This PR now relies on that fail-closed classification for OKE too. Consider adding fake-clientset tests (the deployment side models this well inexpected_resources_rdma_test.go). - 🔵 grep exit-2 (driver/
paramsabsent) folds into "flag absent" (~L191), so a driver-absent node gets the "set the NVreg flag" remediation. Fails closed; theHostPath(~L163) also sets noType. SettingType: HostPathDirectorywould surface a driver-absent node as a distinct mount error. - 🔵
GenerateNamecomment (~L57) references a "node hash" the name doesn't include. Cosmetic.

🟠 Major — OKE RDMA readiness gate cohort is empty — nothing labels OKE nodes pci-15b3.present
This call now fires for OKE (recipeDeclaresRDMAFabric is true because the recipe attaches nic-cluster-policy-oke-*.yaml), so verifyRDMAFabricReady runs. Its probe (rdmaFabricProbeCoverage, ~L1303) builds the cohort by keeping only GPU nodes carrying helper.PCIMellanoxPresentLabel (= feature.node.kubernetes.io/pci-15b3.present). That label is produced only by recipes/components/network-operator/manifests/nfd-network-rule.yaml (a NodeFeatureRule matching vendor 15b3 + device 101c/101e), which the AKS overlay attaches (aks.yaml:180-181) but neither OKE overlay does — gb200-oke-training.yaml:90-91 and l40s-oke-training.yaml:71-72 attach only the NicClusterPolicy. Both OKE values set nfd.enabled:false, and stock GPU-Operator NFD won't emit a vendor-keyed network-class label. Result: no OKE node carries the label → len(cohort)==0 → the probe returns ErrCodeNotFound ("no schedulable Mellanox RDMA-capable GPU nodes observed yet") which never clears. The L40S policy even selects device 101a, which the AKS rule's 101c/101e wouldn't match.
Blast radius: The deployment readiness gate hangs until timeout on every OKE GB200 and L40S training deploy. It fails closed (no false pass) — hence Major, not Blocker — but blocks legitimate deploys. The PR's "NCCL passing" evidence does not refute this: NCCL is the performance validator (selects by device ID, label-independent); this is the deployment validator (filters by label). Independent paths.
Fix: Verify on the BM.GPU.GB200.4 / L40S testbed whether nodes actually carry pci-15b3.present=true. If not (in-tree evidence says they won't), attach an OKE-specific NodeFeatureRule (GB200 IB HCAs; L40S VF IDs 101a/101e) to both overlays, or teach the cohort filter an OCI-appropriate label. If the label is genuinely absent, this escalates to a Blocker.
There was a problem hiding this comment.
Verified as you asked — the label exists on real OKE nodes, and the premise that nfd-network-rule.yaml is its only producer doesn't hold. Three legs of evidence:
- The chart itself deploys the rule.
helm templateof the pinned network-operator26.4.1chart with this PR's exact values (nfd.enabled: false,deployCR: false) still renders thenvidia-nics-rulesNodeFeatureRule labelingpci-15b3.present=true—deployNodeFeatureRulesis a separate chart value defaulting to true, and the rendered bundle values confirm it (deployNodeFeatureRules: truein the emittedvalues.yaml).nfd.enabled: falsedisables only the chart's own NFD deployment; the GPU Operator's NFD (which these recipes deploy) processes NodeFeatureRule CRs regardless of who created them. AKS setsdeployNodeFeatureRules: falseprecisely because it substitutes the targeted manifest rule — the OKE values deliberately do not. - The rule matches by vendor+class, not device ID:
vendor In [15b3],class In [0200, 0207]— so the L40S101aconcern doesn't apply; RoCE PFs/VFs are class0200. - Live cluster: on a production-shaped BM.GPU.GB300 NVL72 OKE cluster running this configuration, all 18 GPU nodes carry
feature.node.kubernetes.io/pci-15b3.present=true, produced by exactly that chart-deployednvidia-nics-rules(ArgoCD tracking-idnetwork-operator:nfd.k8s-sigs.io/NodeFeatureRule:...), and the label-selected RDMA DaemonSets schedule 18/18.
You did surface a real regression vector, though: a future contributor copying AKS's deployNodeFeatureRules: false into the OKE values would starve the gate exactly as you describe. Hardened in 98ca57e — both OKE values files now document the dependency, and a new recipes test (TestOKENetworkOperatorKeepsChartNodeFeatureRule) fails immediately if the flag is ever disabled without a substitute rule manifest.
There was a problem hiding this comment.
The substantive refutation holds — base values.yaml:26-28 sets nfd.deployNodeFeatureRules: true, the OKE files override only nfd.enabled, and the deep merge at pkg/recipe/adapter.go:399-415 preserves it, so the chart's own nvidia-nics-rules NodeFeatureRule produces the cohort label. Empty-cohort handling also fails closed at expected_resources.go:1320-1325. No deploy-time defect.
The guard added to lock that in doesn't work, though. recipes/network_operator_nfr_test.go:58 reads values["deployNodeFeatureRules"] at the top level, but the key is nested under nfd: in every network-operator values file. Neither OKE file has a top-level key, so both subtests take the if !present { return } early exit and pass without asserting anything.
That means the exact mistake the docstring describes — copying AKS's deployNodeFeatureRules: false into an OKE values file — would land the key under nfd:, where the test never looks, and still pass. The test also inspects the raw overlay rather than the merged effective values, so it would equally miss the flag being flipped in the shared base.
Fix is one line: read values["nfd"].(map[string]any)["deployNodeFeatureRules"]. Asserting on merged values via recipe.GetComponentValuesWithContext would be better still, since it covers both the base and the overlay.
This is the only thing I have left on the PR — everything else is verified fixed or resolved.
|
Addressed the review round in 98ca57e (appended): the Major is refuted with rendered-chart + live-cluster evidence (see the inline thread) but its regression vector is now pinned by a recipes test + values comments; the empty-resourceName guard and docstring/comment fixes are in. The pre-existing preflight pod-lifecycle observations (no unit tests; grep exit-2 folding driver-absent into flag-absent) are tracked as #2560 — reused code this PR doesn't touch. |

🔁 Re-review — OKE RDMA fabric wiring
Delta re-review at ccba748b following the fix commit "guard the RDMA gate's OKE label supply and reject nameless resources." Every prior finding was re-derived against the resolved code. Approving — the Major and the Minor are resolved; the rest are nitpicks that are addressed, acceptably deferred, or clarified.
Prior-feedback status
| # | Tier | Finding | Disposition |
|---|---|---|---|
| 1 | 🟠 Major | OKE RDMA gate cohort empty | ✔️ Addressed — gate keys on helper.PCIMellanoxPresentLabel (pci-15b3.present); the chart's default-on nvidia-nics-rules NodeFeatureRule supplies it, now pinned by values comments + TestOKENetworkOperatorKeepsChartNodeFeatureRule + production verification (18/18 GB300 nodes). AKS's deployNodeFeatureRules: false + own-manifest exception documented. |
| 2 | 🟡 Minor | Fail-closed docstring drift | ✔️ Addressed — docstring rewritten; zero-derivable-resources coverage moved to the parser test. |
| 3 | 🔵 Nitpick | NVreg preflight coupled to fabric == fabricEFA |
◐ Addressed-by-doc — coupling retained; comment expanded to explain OKE takes the default fabric env. |
| 4 | 🔵 Nitpick | qualifiedNICResource accepts empty ResourceName |
✔️ Addressed — now errors instead of deriving a phantom <prefix>/; parser test row added. |
| 5 | 🔵 Nitpick | rdmaFabricResource no internal timeout |
✖️ Not addressed (acceptable) — honors caller ctx via select, in-memory render/parse only. |
| 6 | 🔵 Nitpick | Outer render/parse branches untested | ◐ Largely covered — load-fail + distinct-resource + parser cases now driven; only the manifest.Render error branch remains untested. |
Verified non-issue
- BOM
98 → 102images (network-operator5 → 9): the only source change between the two commits is YAML comments, so the +4 (multus-cni, cniplugins,sriov-network-device-plugin,nvidia-k8s-ipam— the L40S RoCE secondaryNetwork stack) is a stale-golden regeneration, not a rendering change. Working tree clean; parity + render goldens committed consistently. ✔️

🔵 — NFR guard test is a hardcoded 2-file allowlist
TestOKENetworkOperatorKeepsChartNodeFeatureRule enumerates values-oke-gb200.yaml / values-oke-l40s.yaml as a literal list.
Blast radius: A future OKE fabric leaf that also depends on the chart's nvidia-nics-rules NodeFeatureRule would not be auto-covered by this guard.
Fix: Non-blocking. If more OKE fabric leaves land, consider deriving the file set (e.g. glob values-oke-*.yaml, or the OKE recipes that declare an RDMA fabric) rather than an allowlist. Matches exactly the two leaves this PR ships, so fine as-is.
Upstream the OKE network fabric, closing gb200-oke-training's 'NET/RDMA intentionally left out until OCI-specific pod RDMA exposure is verified on the testbed' carve-out — the exposure below is validated on a production BM.GPU.GB200.4 NVL72 rack and a BM.GPU.L40S.4 RoCE cluster. - network-operator on both OKE training chains, NicClusterPolicy supplied by manifest (chart deployCR off). L40S (RoCE): SR-IOV VF device plugin advertising nvidia.com/mlnxnics (ConnectX VF device IDs 101a/101e) plus nv-ipam and multus. GB200 (IB): rdmaSharedDevicePlugin over the NVL72 east-west rdma0-3 netdevs, same nvidia.com/mlnxnics resource name; no SR-IOV/nv-ipam. Neither deploys ofedDriver: OCI nodes carry host MOFED in every image. Present in every gpuStack value (fabric is orthogonal to driver/plugin ownership); incompatible with Oracle's opt-in NvidiaNetworkOperator add-on. - GB200 kernel-module-params wiring (NVreg_GrdmaPciTopoCheckOverride=1): dma-buf attach over the IB fabric — GPUDirect RDMA without nvidia-peermem, whose chroot modprobe fails against the -64k Grace kernel. - nccl-all-reduce-bw-net (>= 40, matching gb200-eks-training) added to the gb200-oke training chain; supportedNCCLCombinations[variantNET] gains oke/gb200 with the ported testdata/gb200/oke/runtime-net.yaml TrainingRuntime (IB via the shared HCAs; NVLS/MNNVL forced off). - NicClusterPolicy image digest exemptions (repository/image/version triplet CRD schema, same as the AKS entries).

…eless resources Follow-ups from the multi-persona review round: - Pin the RDMA readiness gate's cohort-label supply chain on OKE: the chart's own nvidia-nics-rules NodeFeatureRule (deployNodeFeatureRules default true) labels vendor-15b3 nodes pci-15b3.present - verified rendered from the pinned 26.4.1 chart with the OKE values and live on a BM.GPU.GB300 NVL72 cluster (18/18 nodes labeled). Comments in both OKE values files plus a recipes test now fail immediately if someone copies AKS's deployNodeFeatureRules:false without also attaching a targeted rule manifest. - qualifiedNICResource rejects a config entry without resourceName instead of deriving a phantom "<prefix>/" the gate would poll until timeout; parser test row added. - Correct the fail-closed test docstring to the cases the table drives (zero-derivable-resources stays covered at the parser level). - Fix a stale generateName comment in the NVreg preflight.

The exposure the carve-out was waiting for exists and is production-validated: a BM.GPU.GB200.4 NVL72 rack (IB east-west over rdma0-3,
rdmaSharedDevicePlugin, both NCCL variants passing) and a BM.GPU.L40S.4 RoCE cluster (SR-IOV VFs via device IDs 101a/101e, nv-ipam + multus). This PR ports that configuration from the downstream data repo, de-specialized: hardcoded scheduling taxonomy replaced by the bundler's system-node scheduling injection, downstream-only tolerations and resource aliases dropped.Independent of #2355 (originally stacked, since de-stacked and re-based on
main): the fabric is deliberately present in every gpuStack profile value (orthogonal to driver/plugin ownership), and each PR merges on its own. The one behavioral interaction — the GB200 kernel-module ConfigMap being consumed only underoperator-managed— is handled in this PR (see Implementation Notes).Fixes: #2345

GB200 needsNVreg_GrdmaPciTopoCheckOverride=1(kernel-module-params ConfigMap, already embedded — this PR adds the wiring).driver.kernelModuleConfigis consumed only when a GPU Operator driver DaemonSet runs (gpuStack=operator-managed); under the default image-driver profile it is rendered but inert, and it cannot move into the profile'soperator-managedfragment (fragments are family-wide; only this leaf ships the ConfigMap — a family-wide reference would dangle on every other OKE recipe's driver pods). The overlay documents this consumption scope, and the NVreg NCCL preflight now covers OKE (gb200NetPreflightApplies: GB200+NET on EKS and OKE) so a host driver missing the flag fails the-netcheck closed with remediation naming both routes — the ClusterPolicy ConfigMap when the operator manages the driver, image/modprobe.dwhen the driver ships in the node image. No silent Socket fallback on either profile.helper.AKSRdmaSharedResource—rdmaFabricResource()renders the recipe's own NicClusterPolicy manifest and derives the advertised resource from the embedded device-plugin config (rdmaSharedDevicePlugin/sriovDevicePlugin, with each plugin's documented default prefix), failing closed on parse failure, zero derivable resources, or multiple distinct ones.TestRDMAFabricResource_RealManifestsparses all three shipped manifests and pins the AKS result to the NCCL consumer's constant so they cannot drift.supportedNCCLCombinations[variantNET]gains oke/gb200 withtestdata/gb200/oke/runtime-net.yaml(NVLS/MNNVL forced off; transport confirmed from the NCCL banner).

Rollout notes: Additive for existing OKE users without RDMA-capable pools (the NicClusterPolicy DaemonSets simply schedule nowhere without matching NICs). Clusters running Oracle's NvidiaNetworkOperator add-on must disable it before deploying these bundles (#2522 tracks failing closed on that automatically once #2355's add-on projection is available).
