What this PR does

This fixes two cleanup failures in the kubernetes suites. The nightly runs failed kubernetes-previous and kubernetes-latest in the replicated storage lane. PR runs fail kubernetes-latest with LINSTOR pools did not return to their pre-suite baseline within 300s.

The replicated lane asked for too much free space at cleanup. It wanted 90 GiB free on every LINSTOR node, and volumes from earlier suites kept srv2 at 83 GiB, so both suites failed without leaking anything (nightly run 36659663201). A replicated suite still needs those 90 GiB for its workers and CDI scratch volumes, so the floor is now checked before the suite starts. If a node is short there, the suite fails with the per-node table and an error that blames the sandbox, not the suite.

Cleanup in both lanes now compares against a baseline recorded before the suite creates anything, and that baseline is no longer free bytes. On a node whose pools are all thick ZFS, linstor sp l does not ask the satellite for free space. The controller fetches it live only for nodes with thin pools and otherwise returns the value cached at the satellite's last report. In LINSTOR v1.33.3 that is FreeCapacityFetcherProto.assembleRequests filtering on hasThinPools, with CtrlStorPoolListApiCallHandler falling back to getFreeCapacityLastUpdated. The last report can be taken while zfs destroy is still freeing blocks in the background. A cleanup that had removed everything then kept polling a frozen figure 0.4 to 0.9 GiB short and failed after 300s. A byte tolerance does not fix that, because the residue is already close to the smallest volume a suite is known to have leaked (1 GiB).

The baseline is now the set of ZFS datasets under each node's LINSTOR pool. It is read with zfs list inside that node's linstor-satellite container. The zpool name comes from the pool's StorDriver/StorPoolName property, because it is data on QEMU nodes and data-srvN in container mode. Cleanup waits until no dataset outside the baseline remains. A destroyed dataset leaves the namespace when zfs destroy returns, whether or not its blocks are still being freed, so background freeing no longer fails the check. A real leak, like the 21 GiB scratch volume left on srv3 in an earlier run, is reported by node and dataset name instead of a KiB difference. A node whose pool cannot be read fails the check. A run that fails before it records a baseline no longer compares against the previous suite's file. Every read the new probe makes runs under timeout -k 5 30, so a hung controller or satellite fails one poll and the wait still ends with its failure message.

The kafka suite deleted its apps but never their PVCs. The chart keeps them on purpose with deleteClaim: false. One run left 35 GiB in tenant-test, 20 GiB of it on srv2, and the backup round trip left its two clusters' volumes in tenant-root the same way. Each test now deletes its clusters' PVCs by strimzi.io/cluster after the apps are gone and waits for them. The kafka test does it from a step cleanup, so it also runs on a failed run.

The tests cover both fixes. hack/linstor-storage-mode_test.bats has cases for a clean cleanup, a volume still listed on the first poll and gone on the next while the cached free capacity stays short, a leaked volume, a node that cannot be read, a hung satellite read, a missing or stale baseline, and the replicated-lane floor. Its fake runs the real controller-side jq filter against a LINSTOR-shaped listing. hack/kafka-suite-pvc-cleanup_test.bats checks that each cluster's PVC delete is in the suite and runs after the app cleanup. One stub line goes into hack/run-kubernetes-talos-diagnostics_test.bats, because that test calls cozy_cleanup with no baseline and only checks the order of the deletes. The new guards were mutation-tested.

Some limits stay as they are. The local lane waits for dataset names to disappear, not for the freed space, and has no free-space floor, so a background destroy can still be freeing blocks when the next suite starts. The 90 GiB precondition in the replicated lane still reads the cached free capacity, and its comment says so. The two kubectl exec reads in cozy_wait_linstor_pool_free were there before this PR and still have no time limit of their own.

Two related problems stay out of this PR. The kafka-metadata suite leaks PVCs the same way, tracked in #4641. The stale comment in examples/backups/kafka/cleanup.sh and the missing PVC pre-clean in the round trip are in #4649.

Closes #4617, closes #4616, closes #4653

Release note

fix(e2e): the kubernetes suites' LINSTOR cleanup compares each node's ZFS datasets against a pre-suite baseline instead of cached free capacity, the replicated lane checks its 90 GiB floor before the suite starts, and the kafka suite deletes the PVCs its clusters keep.

The kubernetes suites' cleanup in the replicated lane demanded 90 GiB
free on every LINSTOR node. Volumes that earlier suites and the
platform legitimately keep can hold a node under that figure even when
the suite reclaimed everything it used, so the cleanup failed suites
that had leaked nothing.

Both lanes now record the per-node baseline before the suite creates
anything and compare against it on cleanup. The 90 GiB figure is what
a replicated suite needs to place its workers and CDI scratch volumes,
so it stays as a precondition checked before the baseline, and a
shortfall there is reported as the sandbox's state rather than the
suite's.

A run that fails before recording its baseline used to leave the
previous suite's file in place for its cleanup to compare against; the
file is now removed when the suite starts.

The kafka chart sets deleteClaim: false on both node pools, so deleting
an app leaves its volumes behind on purpose. The suite deleted its apps
and never the volumes. The 35 GiB a run leaves in tenant-test, 20 GiB
of it on one node, kept that LINSTOR node short of space for the
kubernetes suites that run after it. The backup round-trip leaves its
two clusters' volumes in tenant-root the same way.

Each test now deletes the PVCs by strimzi.io/cluster once its apps are
gone, and waits for them to go. The kafka test does it from a step
cleanup, so a failed run reclaims them too.

📝 Walkthrough

Walkthrough

Kafka suite cleanup deletes PVCs for its test clusters. Kubernetes runs record per-node LINSTOR dataset baselines for both storage classes. The 90 GiB capacity precondition applies only to replicated storage. Cleanup checks each run against its recorded baseline.

Changes

LINSTOR dataset baseline cleanup

Layer / File(s) Summary
Baseline capture and preflight
hack/e2e-chainsaw/_lib/run-kubernetes.sh, hack/linstor-storage-mode_test.bats
The runner removes any prior baseline and captures dataset rows for all three nodes for both storage classes. The 90 GiB capacity check applies only to replicated storage. Tests cover dataset probes, baseline capture, preflight failures, and stale-baseline removal.
Baseline reclamation checks
hack/e2e-chainsaw/_lib/run-kubernetes.sh, hack/linstor-storage-mode_test.bats, hack/run-kubernetes-talos-diagnostics_test.bats
Cleanup polls dataset listings against the saved baseline. New datasets, unreadable nodes, and a missing baseline cause cleanup to fail. Tests cover polling and cleanup outcomes.

Kafka PVC cleanup

Layer / File(s) Summary
Kafka PVC deletion and checks
hack/e2e-chainsaw/kafka/chainsaw-test.yaml, hack/kafka-suite-pvc-cleanup_test.bats
Cleanup deletes PVCs for the kafka-test cluster and, in the backup round-trip, for the source and restore clusters. Bats tests check deletion targets and ordering.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Bug fix · Severity of issue fixed: Medium

Merge Risk: 🔵 Low · up to cb7a5

This change only touches end-to-end test tooling. Two small open concerns remain: how the Kafka PVC cleanup behaves if a deletion races, and whether the stale-baseline test would catch a removed baseline reset. Neither affects production. Both are worth a quick check before merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to cb7a5

The cleanup changes are bounded to named test clusters and preserve existing storage through baseline comparison rather than deletion. No introduced security violation was established. Risk remains low because the backup test operates in the shared tenant-root namespace, while effective permissions and cleanup behavior after earlier failures are not fully verified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • observed — The new PVC deletions select kafka-test in the default tenant-test namespace and kafka-kafka-test plus kafka-kafka-restore in the backup test’s explicit tenant-root namespace. Selectors use fixed cluster labels, not a namespace-wide PVC deletion.

Trust Boundaries and Controls

  • observed — Dataset verification uses Kubernetes exec into the LINSTOR controller and satellites in cozy-linstor to enumerate storage across the expected three nodes. Pool names are passed as quoted command arguments, and the new helper performs listing and comparison rather than storage deletion. Effective credential privileges are not established by this source.

Resilience and Maintainability Implications

  • observed — Backup teardown uses ignore-not-found deletion and waits for both Kafka applications before returning success. The new PVC operations follow that script, but repository evidence does not establish whether they execute after the script fails or times out. Interrupted teardown therefore remains a recovery-coverage gap, not a verified security finding.

official Kyverno Chainsaw documentation delete operation selector not found cleanup timeout

💡 Result:

Official Chainsaw docs:

- **Delete by selector:** `delete.ref` can identify one object by name/namespace or multiple objects using `labels`. ([kyverno.github.io](https://kyverno.github.io/chainsaw/main/reference/apis/chainsaw.v1alpha1/?utm_source=openai))
- **Delete timeout:** Configure the `delete` timeout globally, per test/step, or on the individual delete operation. The docs describe this as the timeout for deleting resources. ([kyverno.github.io](https://kyverno.github.io/chainsaw/0.1.7/configuration/timeouts/?utm_source=openai))
- **Cleanup timeout:** `cleanup` is separate: it controls automatic removal of resources Chainsaw created during a test. Cleanup waits for deletion to finish; its timeout can be configured globally, per test, or per step—not per operation. ([kyverno.github.io](https://kyverno.github.io/chainsaw/0.2.3/quick-start/cleanup/?utm_source=openai))

The docs establish selector syntax and timeout configuration, but don’t specifically say whether a selector matching no resources is treated as success or failure. That behavior remains unresolved in these references. ([kyverno.github.io](https://kyverno.github.io/chainsaw/main/operations/delete/?utm_source=openai))

Kyverno Chainsaw v0.2.15 delete operation source selector no resources not found cleanup timeout

💡 Result:

For **Chainsaw v0.2.15**, the delete action’s source is `file` or `ref`—not a live label/field selector. The runner resolves the source into resources, then creates one delete operation per resource. **Inference:** if the source resolves to zero resources, there are no delete operations to run; this differs from a `kubectl delete ... -l ...` selector, which queries the cluster and may print “No resources found.” ([github.com](https://github.com/kyverno/chainsaw/blob/v0.2.15/pkg/runner/operations/delete.go))

A delete operation has its own timeout (`delete.timeout`); the v0.2.15 runner passes it to the delete operation. **Cleanup timeout is separate**: it applies when Chainsaw removes resources created for a test, not to an explicit `delete` step. Increasing cleanup timeout therefore won’t fix an explicit delete timing out; configure the delete timeout instead. ([github.com](https://github.com/kyverno/chainsaw/blob/v0.2.15/pkg/runner/operations/delete.go))

The source confirms resource expansion and timeout wiring, but doesn’t establish the exact error behavior for an empty source or selector. If you share the delete YAML and the error text, I can pinpoint whether it’s empty source expansion, a delete failure, or test cleanup. ([github.com](https://github.com/kyverno/chainsaw/blob/v0.2.15/pkg/runner/operations/delete.go))

💡 Result:

In **Chainsaw v0.2.15**, `pkg/runner/operations/delete.go` doesn’t handle `NotFound` itself. It constructs the delete operation and returns the result of `op.Exec(...)`, so whether a missing resource is ignored or reported as an error is determined by the delegated `pkg/engine/operations/delete` implementation. ([raw.githubusercontent.com](https://raw.githubusercontent.com/kyverno/chainsaw/v0.2.15/pkg/runner/operations/delete.go))

I couldn’t verify that delegated implementation’s `NotFound` behavior from the available source, so the runner file alone doesn’t establish whether deleting a missing resource succeeds.

Set the explicit delete timeout to 8m.

This is an explicit delete operation. The suite-level cleanup: 8m does not override the global delete: 5m timeout. PVC deletion can therefore fail after 5m.

A label ref with no matches expands to no delete operations, so the empty-selection case does not need a guard.

Require the test to detect stale-baseline removal.

The current assertion accepts rc=1, which occurs because the malformed legacy baseline and broad kubectl stub make _cozy_linstor_pool_datasets fail. If run_kubernetes_test stops removing the previous baseline, the test still passes.

Require status 2, which is returned only when cleanup finds no recorded baseline:

550-571: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Assert the missing-baseline diagnostic.

The negative assertion is valid. cozy_wait_linstor_pool_baseline returns 2 for a missing baseline, while cozy_cleanup prints the leak message only for pool_rc == 1. That assertion can catch a regression that misclassifies the missing baseline as a leak.

The test does not assert the expected missing-baseline diagnostic. Add this positive assertion:

Suggested assertion
   if printf '%s\n' "$output" | grep -Fq 'did not return to the pre-suite level'; then
     echo "cleanup blamed the suite for a leak although it stopped before recording a baseline: $output" >&2
     return 1
   fi
+  if ! printf '%s\n' "$output" | grep -Fq 'no LINSTOR pool baseline was recorded'; then
+    echo "cleanup did not report the missing baseline: $output" >&2
+    return 1
+  fi

For a node with only thick ZFS pools, `linstor sp l` reports the free
capacity cached at the satellite's last report rather than asking the
satellite, and that report can land while `zfs destroy` is still
freeing blocks in the background. A cleanup that had removed every
volume it created could then wait out its whole budget against a
figure that never moved. That residue has reached about 0.9 GiB, with
no known upper bound, against 1 GiB for the smallest volume a suite is
known to have leaked, so a byte tolerance has no safe value between
the two.

Record the datasets under each node's pool before the suite, read with
`zfs list` on that node's satellite, and wait until no dataset outside
that set remains. A leaked volume is then reported by name and node,
and a destroy still freeing space in the background does not count.

The check on kafka-2-backup-roundtrip's finally block classified each
op with if/then/elif/else, which yq only gained in v4.54.1. The CI
runner's yq predates that and rejects the whole expression with a
lexer error, so the test failed there while passing locally.

Have yq emit the plain facts per op and let awk name it. The round-trip
document is cut out before that query, because in a multi-document file
yq also evaluates an array literal against the documents a select
drops and prints a line for each.

Replicated lane path (90 GiB precondition, zfs list on qemu nodes) ran only against bats fakes, PR runs use local storage class, so next nightly is the real check.

timeouts.delete: 8m in kafka test is not needed for me, PVC deletes took under a second in E2E log.

Title says replicated-lane but diff changes both lanes.

## What this PR does

The kubernetes suites' LINSTOR cleanup check now compares dataset names
per node, and prints the leftover names when it fails (#4651). This PR
puts the rest of what a triager needs into `cozyreport.tgz` on every
run, green or red: the size of each dataset, its `origin` and
`creation`, the snapshots, the pool's pending frees, and the LINSTOR
volume list.

What `hack/cozyreport.sh` now collects:

- `linstor/zfs-pools.txt`: the zpool behind each ZFS storage pool, per
node, taken from `StorDriver/StorPoolName` in `linstor
--machine-readable sp l`.
- `linstor/zfs/<node>.txt`: that node's satellite runs `zpool get -p
freeing,leaked,allocated,free` and `zfs list -p -t all -o
name,used,avail,refer,origin,creation -r` over the node's pools.
- `linstor/volumes.txt`: `linstor v l`, next to the existing
`resources.txt`.

Sizes are exact bytes, so the sizes of leftover datasets can be summed
against the pool root's `avail`. That `avail` can differ from
`storage-pools.txt` without anything leaking: on a node with only thick
pools, `linstor sp l` serves the free capacity cached at the satellite's
last report. A dataset LINSTOR could not destroy because snapshots
depend on it is renamed to `_deleted_<name>` in the same pool, so a
search for leftovers has to look for that prefix as well as `pvc-`.

A pool that `zpool get` or `zfs list` cannot open does not cost the
listing of the other pools. `zpool get`'s message and exit status go
into the listing, and `zfs list` lists the rest. A node LINSTOR names no
ZFS pool for gets a note instead of a listing, because `zfs list -r`
with no pool argument lists every pool on the machine. A satellite whose
`spec.nodeName` cannot be read gets a note that says so. All reads go
through the bounded exec reader, like the other LINSTOR reads, and the
time budget in the script header counts them.

The second commit changes how that reader marks a read that wrote output
and then exited non-zero without hitting the timeout. It used to append
`TRUNCATED ... part way through, not because the command finished`. But
`kubectl exec` passes the remote command's status through, and `zfs
list` over one missing pool prints a complete listing of the others and
exits 1. The marker now names the exit status and says the status can't
tell an error after complete output from a cut stream. This changes the
marker for every LINSTOR exec read. The timeout marker stays as it was.

Tested with `hack/cozytest.sh hack/cozyreport.bats`. The new tests run
the controller and satellite shells against stub `linstor`, `zpool` and
`zfs`, with the real `jq`. They cover a failed and an unparsable
storage-pool read, a pool row with a missing, empty or blank backing
name, a non-ZFS pool, a pool name with a space, a pool that `zpool` and
`zfs` cannot open, a failing `zfs`, and an unreadable node name. A test
goes red if any of these break: the filter that keeps non-ZFS pools out,
the filter that drops a missing, empty or blank pool name, the jq exit
status, the `zpool` fallthrough, the node-name note, or the reader's new
wording.
