In `@pkg/test/ginkgo/node_resource_pool.go`:
- Around line 155-157: Update createStaticNodeResourcePool so the
no-worker-MachineSet case returns errMachineAPIUnavailable instead of a
standalone fmt.Errorf, preserving any useful context through wrapping if needed.
Ensure executeNodeResourceTests can recognize the sentinel with errors.Is and
skip the NodeResource test bucket.
In `@pkg/test/ginkgo/node_resource_runner.go`:
- Line 192: Update GetNextTestToRun to track the time since the last successful
test dispatch or completion and enforce a bounded no-progress deadline while
waiting on nrs.cond. When the deadline expires, mark all remaining tests as
failed with a clear reason that no node can satisfy them, then return nil so
executeNodeResourceTests can finish instead of blocking indefinitely. Preserve
normal condition-variable signaling and reset the progress timer whenever
dispatch or MarkTestComplete makes progress.
In `@test/extended/node/additional_storage_api.go`:
- Line 34: Remove the suite-level NodeResource labels from the Ginkgo Describe
blocks and assign each independent It in
test/extended/node/additional_storage_api.go (line 34) and
test/extended/node/node_e2e/probe_termination.go (line 26) its own unique
NodeResource label, preserving node placement requirements while allowing tests
to run in parallel.
In `@test/extended/node/image_volume.go`:
- Around line 78-82: Update test/extended/node/image_volume.go lines 78-82 by
removing the nodeName cache guard so BeforeEach always calls GetNodeResource for
the currently reserved node. In test/extended/node/nested_container.go line 20,
use GetNodeResource with the "nested_container" resource name and pin the pod to
that node, or remove the NodeResource tag if dedicated-node scheduling is
unnecessary; update both affected sites accordingly.
Apply the same fix in `@test/extended/node/nested_container.go` at line 20.
In `@test/extended/node/node_e2e/node.go`:
- Around line 94-95: Schedule each test pod on its reserved NodeResource node:
in test/extended/node/node_e2e/node.go lines 94-95, pass the resolved node from
GetNodeResource into the dev-fuse pod specification via NodeName or hostname
NodeSelector; in test/extended/node/zstd_chunked.go line 18, resolve
zstd_chunked with GetNodeResource and set the created pod’s corresponding
scheduling field.
In `@test/extended/node/node_swap_cnv.go`:
- Line 41: Update TC9 to obtain target nodes through GetNodeResourceNodes and
perform all drop-in mutations and kubelet restarts only on those nodes; reserve
the full required node count in the NodeResource declaration, or exclude TC9
from this NodeResource suite if it must target non-pool CNV workers.
In `@test/extended/node/node_swap.go`:
- Line 41: Update the affected node swap tests and their GetNodeResourceNodes
requests so they either reserve all dedicated worker nodes with numNodes=all,
matching the plural assertions and loops, or explicitly revise the tests to
validate only one worker node; keep the selected contract consistent across the
tests at the referenced cases.

Give each independent Ginkgo test its own NodeResource label.
A suite-level label is reused by multiple independent tests. The scheduler uses the label as an exclusivity key, so these tests run serially instead of in parallel.

Restore the custom-role guard before assigning the reserved node to a custom machine configuration pool.
These tests resolve a reserved node and then add it to a custom pool without verifying that it has no stale custom role. Leftover role labels can create ambiguous pool membership and cause the configuration wait to time out or apply to the wrong node set. Call EnsureNodeHasNoCustomRole before creating the custom pool, as the analogous node test does.
Also applies to test/extended/node/runc_upgrade_cases.go#L725-L729.

Use a unique NodeResource label for each It.
Line 22 makes all three nested tests use label=node_e2e. Each test also resolves that same label. Completion releases reservations by label, so one test can release the node while another test still uses it. Move the NodeResource tag to each It, assign unique labels, and update each lookup call to use its matching label.
Based on learnings: independent NodeResource reservations must use unique labels because completion releases all nodes reserved under that label.

Remove this suite from the NodeResource bucket. The suite updates the cluster-scoped image.config.openshift.io/cluster object and waits for the standard worker and master MCPs. GetNodeResource only selects the reserved node for assertions; it does not scope the update. The registry change can roll out to non-reserved workers and violate NodeResource pool isolation.

Reserve two nodes for TC9.
TC9 reads only nodes with the node_swap_cnv reservation. This suite reserves one node. The len(cnvNodes) < 2 branch at Line 620 therefore always skips TC9.
Move TC9 to a separate NodeResource:numNodes=2 suite, or reserve two nodes for this suite.

Move the NodeResource split before the Early/Late split. crio_goroutinedump.go:70 has both [Late] and [NodeResource:...] tags. The [Late] split removes it before isNodeResourceTest runs, so it executes through the generic queue instead of the dedicated pool.

Route NodeResource retries through executeNodeResourceTests. performRetries always sends retries to the generic q.Execute queue. It does not check isNodeResourceTest. The dedicated pool teardown runs before performRetries, so NodeResource retries are not guaranteed to use dedicated nodes.

Validate complete NodeResource tag tokens.
FindStringSubmatch and strings.Contains can accept a valid-looking substring inside a malformed token such as [[NodeResource:numNodes=1,label=x]]. In openshift/disruptive-longrunning, this can route the test to the dedicated pool and schedule it as a NodeResource test. Extract bracket-delimited tokens first, normalize them, validate them with an anchored ^...$ expression, and use the same validation in isNodeResourceTest.

Bound scheduler API calls with a finite deadline. Run creates ctx with context.Background(), so testCtx has no deadline. GetNextTestToRun holds nodeResourceScheduler.mu while Kubernetes Get and Patch calls run. A stalled request can block MarkTestComplete from releasing reservations. Add a finite deadline or move these calls outside the mutex with explicit pending-reservation coordination.

Keep a node unavailable until its prior label cleanup completes.
Lines 244-250 delete the reservation and wake schedulers before lines 255-259 remove the old label. A worker can reserve and label the node for test B before test A's delayed unlabelNode patch runs. That patch deletes the label unconditionally, including test B's new label. Test B can then fail its NodeResource lookup.
Do not make the node schedulable until its previous label removal succeeds. Keep failed cleanup in an explicit unavailable state and retry or handle it during terminal cleanup.

Remove the NodeResource tag from this suite.
updateCRIOCredentialProviderConfig updates the cluster-scoped CRIOCredentialProviderConfig named cluster. The dedicated MachineSet uses the same worker MCP as the original workers, and WaitForMCPsConfigSpecChangeAndUpdated waits for worker and master MCP updates. The suite can therefore roll original worker nodes while it verifies only reserved nodes. Run it through the existing disruptive path.

Status: Design Review / Draft implementation done
Builds on the
[NodeResource:numNodes=N,label=X]scheduler design originally proposed in #31516 adding a dedicated static worker node pool so the NodeResource test bucket no longer runs on the cluster's real worker nodes.Recap: the NodeResource scheduler (from #31516)
Introduces a
[NodeResource:numNodes=N,label=X]tag for tests that need exclusive access to worker nodes. AnodeResourceSchedulerlabels N worker nodes before each test runs and removes the labels after completion. Tests useGetNodeResource(ctx, oc, label)to discover their assigned node. The scheduler uses the samesync.Condwait/broadcast pattern as the existing conflict-based scheduler — workers block when no free nodes are available and wake when a test completes.numNodes=allrequires every worker node to be free, naturally serializing cluster-wide tests likeimage_mirror_set.All tests under
test/extended/node/(exceptdra/) are tagged and run in a dedicated "NodeResource" execution bucket after MustGather. Tests that previously picked an arbitrary worker now target their labeled node, preventing concurrent tests from interfering with each other on the same node.What's new in this PR: a dedicated static node pool
Previously the scheduler labeled the cluster's real worker nodes. That has two problems observed on payload runs:
PodDisruptionBudgetstarvation if too many workers go unavailable at once.currentConfig != desiredConfig) or otherwise "not clean" from a previous test when the next test picks it up, which we saw surface as a livenodes not Ready ... cluster may be recovering from previous testfailure in a payload run of Run long running tests in parallel #31516.This PR provisions a dedicated, disposable pool of worker nodes up front (default 3, overridable via
OPENSHIFT_TESTS_NODERESOURCE_POOL_SIZE) and runs every[NodeResource]test exclusively on that pool, leaving the cluster's original worker nodes untouched for the rest of the run.How it works:
MachineSet'sproviderSpecinto a new MachineSet with the desired replica count. Cloning keeps this platform-agnostic — whatever instance type/image/network AWS, GCP, Azure, etc. already use for workers is reused as-is.Ready.newNodeResourceSchedulerno longer discoversnode-role.kubernetes.io/workernodes itself) and run the NodeResource bucket exactly as in Run long running tests in parallel #31516.The pool nodes are plain additional workers — same role, same MachineConfigPool, no taints — so no other cluster behavior needs to change to accommodate them; they're just extra capacity dedicated to these tests for the duration of the run.
If the cluster has no Machine API to provision from (e.g. Single Node OpenShift), the NodeResource bucket is skipped with a clear reason rather than failed.
After this PR
Time Savings
Node pool bring-up (VM boot + ignition + kubelet join) is expected to add roughly 15-20 minutes up front; the goal of this PR is reliability (no more node-not-Ready flakes) more than additional speedup, and results will be updated here once a payload job has run.
