the exact namespace name created by that invocation and delete only that
namespace. Remove the prefix-based iteration over all openshift-must-gather-
namespaces while preserving the existing deletion command and cleanup logging
for the tracked namespace.
- Around line 33-41: Update the must-gather specification’s It block to register
the shared reporter’s ReportIfFailed() alongside its existing setup, ensuring
failed tests dump the configured namespaces and CRDs.
- Around line 81-90: Update the template discovery flow around
APIClient.Resource(...).List to fail immediately when listErr is non-nil, using
the test’s existing assertion mechanism; only populate templateNames from
templateList.Items after the assertion succeeds.
- Around line 177-185: Update createMustGatherDestDir to create and return a
unique child directory under the selected ARTIFACT_DIR or temporary base on
every invocation, rather than reusing the fixed sbr-must-gather path. Ensure the
directory is created successfully before returning it so collectRelativePaths
only sees artifacts from the current run.

Port the SBR must-gather test from ocp-edge-auto to system-tests as a non-destructive Go/Ginkgo test. The test validates that oc adm must-gather with the RHWA image collects all SBR-related diagnostic data: - Node YAML files for all cluster nodes - All three SBR CRD definitions - SBR controller pod data - StorageBasedRemediationTemplate CRs (if present) The must-gather image is resolved via MUST_GATHER_IMAGE env var, then NHC CSV version lookup, with a hardcoded fallback.

Missing Serial decorator. oc adm must-gather creates cluster-wide openshift-must-gather-* namespaces. If this test runs in parallel with another must-gather test (e.g. the FAR must-gather test from PR #81), the namespace cleanup logic at cleanupMustGatherNamespaces could interfere with the other test's namespaces or vice versa. Add Serial alongside Ordered.
There was a problem hiding this comment.
Added Serial alongside Ordered (HEAD 09b8052a, must_gather.go: Describe("SBR Must-Gather Diagnostics", Serial, Ordered, ...)), matching the FAR must-gather spec in #81 (Serial, Ordered).
The race is real: cleanupMustGatherNamespaces deletes every openshift-must-gather-* namespace created after testStartTime, so a concurrently-running must-gather spec could have its namespace deleted mid-collection (and vice versa). Ordered only orders specs within this container and does not prevent parallel execution; Serial stops this spec from running in parallel with other specs in the same suite under -p, closing the in-suite window. It does not serialize against a separate suite package (e.g. far-operator) or an unrelated cluster gather, but under plain ginkgo -r those do not run concurrently anyway.

PR description claims two validations that are not implemented in the code:
- "Validates SBR controller pod data is collected (using path-segment matching
/pods/<name>/)" -- missing - "Conditionally validates
StorageBasedRemediationTemplateCRs via dynamic client" -- missing
The README correctly reflects what the code does (node YAMLs, CRD definitions, MachineHealthCheck). Either add the missing validations or update the PR description.

Updated the PR description (the second option you offered): removed the controller-pod (/pods/<name>/) and StorageBasedRemediationTemplate CR bullets, which the test does not implement. The changed section now matches the code and README: node YAMLs for all cluster nodes, all 3 SBR CRD definitions, and MachineHealthCheck data.

context.TODO() for node listing -- use a bounded context for consistency with the pattern being established across the codebase (see PR #79 for the same cleanup in NHC tests).
There was a problem hiding this comment.
Switched the node listing from context.TODO() to a bounded context (HEAD 09b8052a, the By("Capturing cluster state before must-gather for validation") step): context.WithTimeout(context.Background(), medik8sparams.DefaultTimeout) (300s) with a deferred cancel. Consistent with #79, which replaced context.TODO() in the NHC cleanup with a real context.

The shared waitForSBRCReady helper (used by 12 SBR tests) flaked ~25% on the e2e-sbr-aws-odf job: whichever SBRC test runs first on a freshly provisioned ODF cluster timed out at 420s with "DaemonSet sbr-agent-<name>: 0/3 pods ready", while every later SBRC came up in ~90s. The suite runs with --randomize-all, so any SBRC test can be the first cold-start victim. Root cause is the one-time cold start of the first CephFS PVC bind plus the SBD device-init Job, and the failure was opaque (no diagnostics beyond the pod count). - Raise SBRCReadyTimeout 7m -> 10m to absorb the cold start; a ready DaemonSet returns immediately, so healthy runs never wait longer, and the ginkgo suite (24h) and ci-operator step budgets are unaffected. - On timeout, dump readiness diagnostics as a lazily-evaluated Gomega description (rendered only on failure, inside the [FAILED] block): DaemonSet status; the agent pods' non-ready conditions, PVC bindings, and init/main container states; every PVC and Job in the namespace; and the most recent Warning events. Pods are found via the DaemonSet's own label selector (falling back to the name prefix), and the API calls run under a bounded context so a wedged apiserver cannot hang the already-failed test.

Summary
This PR adds the SBR must-gather diagnostic test and, in the same pass, hardens the shared SBRC agent-DaemonSet readiness wait that was causing a recurring CI flake on the
e2e-sbr-aws-odfjob.1. SBR must-gather diagnostic test (OCP-88733)
Adds a non-destructive Go/Ginkgo test that runs
oc adm must-gatherwith the RHWA image and verifies the output contains all SBR-specific diagnostic artifacts.tests/sbr-operator/tests/must_gather.gotests/sbr-operator/internal/sbrparams/const.goSBRCRDNamestotests/sbr-operator/internal/sbrparams/sbrvars.goThe test resolves the must-gather image via
MUST_GATHER_IMAGE, NHC CSV lookup, or a hardcoded fallback; runsoc adm must-gatherwith a bounded timeout; validates node YAMLs for all nodes, the three SBR CRD definitions, and MachineHealthCheck data; and cleans up leftoveropenshift-must-gather-*namespaces.Polarion: OCP-88733

2. Harden the SBRC agent-DaemonSet readiness wait (flake fix)
The shared
waitForSBRCReadyhelper (called by 12 SBR tests) flaked ~25% of the time on thee2e-sbr-aws-odfjob: whichever SBRC test ran first on a freshly provisioned ODF cluster timed out after 420s withDaemonSet sbr-agent-<name>: 0/3 pods ready, while every later SBRC on the warmed CSI path came up in ~90s. Because the suite runs with--randomize-all, any SBRC test can be the first cold-start victim (it most often surfaced as thedetectOnlyMode[BeforeAll]). Root cause is the one-time cold start of the first CephFS PVC bind plus the SBD device-init Job; the failure was also opaque, reporting only the pod count.SBRCReadyTimeoutfrom 7m to 10m to absorb the cold start. A ready DaemonSet returns immediately, so healthy runs never wait longer, and the ginkgo suite (24h) and ci-operator step budgets are unaffected.[FAILED]block): DaemonSet status; each agent pod's non-ready conditions, PVC bindings, and init/main container states; every PVC and Job in the namespace; and the most recent Warning events (with age). Pods are found via the DaemonSet's own label selector, falling back to the<name>-prefix; all API calls run under a bounded context so a wedged apiserver cannot hang the already-failed test.Same-signature failures on the periodic job (no PR involved): builds 2085654011062521856 and 2085380489136312320.
