repair creates the Job as soon as it is invoked, with no way to review it first. With -o yaml or -o json it now creates nothing and prints the repair Job manifests instead:

$ kubectl directpv repair 3b562992-f752-4a41-8be4-4e688ae8cd4c -o yaml > repair.yaml
$ kubectl apply -f repair.yaml

Output is a single kind: List in both formats, like list drives, so kubectl apply -f - accepts either.

Notes

  • Behaviour without -o is unchanged.
  • --dry-run keeps its existing meaning of xfs_repair no-modify mode and is orthogonal to -o; it is carried into the generated manifest when both are given.
  • Job construction moved into newRepairJob, shared by the create path and the new GetRepairJobs, so the two cannot drift. It gains an explicit TypeMeta — client-constructed objects serialize with no apiVersion/kind, which would make the manifest unusable with kubectl apply.
  • -o still requires a reachable cluster: the Job's image, tolerations, pull secrets and security context come from the node-server DaemonSet, and drive→node resolution needs the CR.

docs/tools/repair.sh

The script takes the same --output flag. In that mode it suspends no drive, deletes no pod and creates no Job — it prints the prerequisite commands to stderr so stdout stays a clean, applicable manifest, and invokes the plugin once for all drive IDs so the result is a single List:

$ ./repair.sh --output yaml <DRIVE-ID> > repair.yaml
# drive <DRIVE-ID> is not suspended; run below commands before applying the manifests
kubectl directpv suspend drives <DRIVE-ID> --dangerous
kubectl delete pod minio-0 --namespace tenant-a

The script had also drifted from the plugin, and those fixes are included:

  • get_suspend_value queried directpvvolumes with a drive ID, so the lookup always failed and is_suspended always returned false — it now queries directpvdrives.
  • kubectl directpv suspend "${drive_id}" was missing the drives subcommand and --dangerous.
  • No --force passthrough.

All three are supported by the plugin today (verified against the built binary); the script simply had not kept up. It is now in sync with the copy shipped in the AIStor docs.

Testing

New test_repair_manifest functional test, picked up by the existing functests workflow (no CI config change). For both formats it asserts the manifest is a List carrying the requested flags, that no Job is created, that applying it produces a Job that runs to completion, and that -o wide is rejected.

Verified locally: go build ./..., go test ./..., golangci-lint (0 issues), shellcheck. The script's argument parsing and its suspended / unsuspended / cluster-unreachable paths were exercised against a kubectl stub.

Review Change Stack

📝 Walkthrough

Walkthrough

The repair command supports YAML and JSON Job manifest output. It retrieves manifests without creating Jobs, while normal repair execution remains available. The repair script adds output and force options, and functional tests validate generation, application, completion, cleanup, and format validation.

Changes

Repair manifest workflow

Layer / File(s) Summary
Repair Job construction and retrieval
pkg/admin/repair.go
newRepairJob centralizes repair Job creation. GetRepairJobs builds manifests without creating Jobs.
Repair CLI output mode
cmd/kubectl-directpv/repair.go, docs/command-reference.md, docs/drive-management.md
The command validates yaml and json output, returns manifests as a Kubernetes JobList, and documents generation and application.
Repair helper script workflow
docs/tools/repair.sh
The script parses --force and output options, validates drive IDs, reports prerequisites, generates manifests, and preserves direct repair execution.
Manifest validation and test wiring
functests/common.sh, functests/tests.sh
Functional tests validate YAML and JSON output, no-job dry runs, applied Job completion, cleanup, and rejection of wide.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 0afbb

The PR adds manifest-only repair output, but the accompanying functional tests can leave applied Jobs behind on failure and may not reliably prove that unsupported output is rejected. This is a bounded test reliability risk that should be fixed or explicitly accepted before merge.

🔒 Security & Privacy | 🟡 Minor | ⚡ Quick win

Use a unique temporary manifest file.

The predictable /tmp/repair.${format} path permits symlink and time-of-check/time-of-use attacks from a local actor. Create the file with mktemp and use that path for generation, validation, and application.

Source: Linters/SAST tools

Comment thread functests/common.sh
With `-o yaml` or `-o json`, `repair` creates no Job and prints the repair Job
manifests instead, so they can be reviewed before being applied:

    $ kubectl directpv repair 3b562992-f752-4a41-8be4-4e688ae8cd4c -o yaml > repair.yaml
    $ kubectl apply -f repair.yaml

Output is a single `kind: List` in both formats, like `list drives`. Behaviour
without `-o` is unchanged, and `--dry-run` still means `xfs_repair` no-modify
mode, carried into the generated manifest.

repair.sh takes the same flag. In that mode it suspends no drive, deletes no pod
and creates no Job; the prerequisite commands are printed to stderr so stdout
stays an applicable manifest. The script had also drifted from the plugin: it
looked up the suspend label on directpvvolumes using a drive ID, called
`suspend` without the `drives` subcommand or `--dangerous`, and had no `--force`
passthrough. Those are fixed here.

Adds a `test_repair_manifest` functional test that applies the generated
manifest and asserts the resulting Job completes.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Clean up the applied Job on every failure path.

After Line 572, each failure path returns before Lines 602-613. A failed or timed-out test leaves repair-${drive} in the cluster. That Job can affect a retry because repair Job names are deterministic.

Install cleanup after a successful apply. Run it before each failure return, or use a function-scoped trap and clear it after normal deletion.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Use the same valid repair flags for the unsupported-format test.

This command omits --dry-run --force, unlike the known-valid manifest commands above. It can return nonzero for another repair precondition, so the test does not prove that wide is rejected. Add --dry-run --force before -o wide.
