OCPBUGS-117271: Improve TNF recovery test stability: AfterEach cleanup, migration-threshold, east-west fixes - #31530
Conversation
…threshold Recovery tests were failing at 57-95% pass rate due to two root causes: 1. No AfterEach cleanup: failed tests leaked cluster state (maintenance mode, disabled etcd-clone, stale CRM attributes) causing cascade failures in subsequent tests. 2. No migration-threshold protection: Pacemaker's default retry budget would exhaust during node recovery, permanently abandoning etcd restarts and causing false test failures. Changes: - Add comprehensive AfterEach cleanup block mirroring the disruption test pattern (which passes at 100%): reset maintenance mode, unstandby nodes, enable etcd-clone, clear CRM attributes, pcs resource cleanup, validate cluster and etcd health. - Set migration-threshold=INFINITY with DeferCleanup for 5 tests that trigger node failures: double graceful shutdown, sequential graceful shutdowns, graceful+ungraceful failure, kernel panic recovery, and simultaneous graceful shutdown. - Replace bare o.Expect with o.Eventually (5min timeout) for etcd container check in simultaneous graceful shutdown test to avoid race with recovery. - Fix variable shadowing (err := to err =) after migration-threshold block.

…opologies
The initial-and-final-operator-log-scraper monitor test hard-fails on
DualReplica (TNF) and SingleReplica (SNO) topologies when transient API
errors occur during node recovery. On HA clusters these errors indicate
real problems, but on reduced topologies they are expected during
disruptive tests (503s from apiserver restart, kubelet proxy auth
failures, terminated containers, connection refused).
Changes:
- Add isReducedTopology() to detect DualReplica/SingleReplica via the
Infrastructure CR (same pattern as etcd-log-analyzer).
- Add isTransientScrapeError() as a local classifier for recovery-related
errors (503, NotFound, connection refused/reset, TLS timeout, kubelet
down, terminated containers). Does not modify the shared
IsTransientAPIError in pkg/monitortestlibrary.
- Retry pod listing (Pods("").List) up to 4 times with exponential
backoff on transient errors.
- Skip per-pod log read errors that are transient instead of accumulating
them as hard failures.
- Wrap StartCollection and CollectData errors as FlakeError on reduced
topologies when transient, producing a visible flake in CI instead of
a blocking job failure. HA behavior remains strict.
- Tighten pod name filter from Contains("operator") to
Contains("-operator-") to exclude marketplace catalog pods like
redhat-operators-*.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Resolve and retain topology before scan failures.
isReducedTopology runs only after scanAllOperatorPods returns an error. If the API server fails both the pod list and Infrastructures().Get request, this function returns false. StartCollection and CollectData then return a regular error instead of FlakeError.
Detect and store the topology before scanning. Preserve strict handling when topology detection is unknown.

…node discovery Address three CodeRabbit findings: 1. Cache topology detection in StartCollection (when API is healthy) instead of querying it after scan failures when the API may be down. Store as reducedTopology field and reuse in CollectData. 2. Only skip transient log-read errors on reduced topologies. On HA clusters, transient per-pod errors are now accumulated and reported as hard failures, preserving full log coverage visibility. 3. Retry node discovery in recovery test AfterEach (up to 2 minutes) instead of silently skipping cleanup when GetNodes fails. Prevents leaked cluster state from cascade-failing subsequent tests.

- Around line 154-160: Update the error handling around PodInterface.List so any
non-nil listErr is handled independently of whether pods is nil. Return listErr
immediately for context cancellation and other errors, and use lastListErr only
when the failure is wait.ErrWaitTimeout; preserve the existing wrapped error
messages while ensuring a non-nil PodList cannot suppress the listing failure.

- Around line 135-158: Remove the trailing “; true” from the maintenance-mode,
per-node unmaintenance, and unstandby commands in the cleanup blocks, preserving
each pcs command’s exit status so the existing error checks report Pacemaker
cleanup failures.
- Around line 165-171: Update CrmDeleteAttributeViaDebug and
CrmDeleteTransientAttributeViaDebug to return the underlying crm_attribute
command error instead of masking failures with “; true”. In the cleanup flow
around the stale learner_node and force_new_cluster deletions, capture each
returned error and log it while continuing cleanup so stale CRM state failures
remain visible.
- Around line 173-177: In all five migration-threshold setup blocks, register
DeferCleanup immediately after the successful getMigrationThreshold call and
before setMigrationThreshold, so cleanup remains registered if mutation returns
an error. Remove the broad AfterEach fallback that deletes any current INFINITY
value, or make it restore only state created by the test; preserve
restoreMigrationThreshold’s existing best-effort logging behavior.

After both nodes reboot simultaneously, the API server is unavailable for several minutes. The tests were immediately attempting oc port-forward with a 5-second poll interval, generating ~360 failed subprocess attempts before timing out with "could not get a etcd client". Add IsClusterHealthyWithTimeout gate and use ThirtySecondPollInterval for all four double-reboot test variants. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

The "simultaneous graceful shutdown of both nodes" test (shutdown -r 1) had the same issue as the cold-boot tests: after both nodes reboot, the API is unavailable and the test immediately polls etcd with a 5-second interval. Add IsClusterHealthyWithTimeout gate and ThirtySecondPollInterval. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Both validateEtcdRecoveryState and validateEtcdRecoveryStateWithoutAssumingLeader accepted a pollInterval parameter but hardcoded utils.FiveSecondPollInterval in EventuallyWithOffset. Callers passing ThirtySecondPollInterval had no effect. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
After node replacement, the PodNetworkConnectivityCheck sometimes never transitions to Reachable=True because OVN-K does not resync the dataplane for the new chassis without a pod restart. The OVN recovery was only in the AfterEach cleanup (triggered after the test already failed). Move the recovery into the test flow: if the initial 12min east-west check fails, restart ovnkube-node/control-plane pods, wait 60s for dataplane settle, then retry the check. Also fix validateEtcdRecoveryState and validateEtcdRecoveryStateWithoutAssumingLeader which accepted a pollInterval parameter but hardcoded FiveSecondPollInterval.

Summary
Split from this PR into #31597 per review feedback: monitor test / operator-log-scraper topology awareness (the OCPBUGS-111056 fix itself) now lives there. This PR is scoped to TNF (DualReplica) recovery test suite stability fixes only.
