Review comments at @scripts/maintain-longhorn-clients/main.go:
- Around line 380-403: Update the post-migration readiness checks in prepare to
poll clientsReady via e.poll instead of failing on a single transient check;
preserve the existing drift error context for completed maintenance. When no
journal exists, allow polling only while the live selector is empty, and retain
the error for selectors outside the reviewed migration.
- Around line 371-379: Update the journal handling in prepare so a journal in
the "restored" phase can be superseded: verify live that every journaled
resource is unpaused and retains its original UID, then replace the journal
using a UID- and resourceVersion-tested patch. Keep rejecting other unfinished
phases. Add an engine_test.go case where a different holder prepares after a
prior run failed and restored.
- Around line 76-84: Update client.patch and the pausePatch/restorePatch flows
to retry a bounded number of times only after a resourceVersion test or conflict
failure. Before each retry, re-read the object, rerun ownership and spec checks,
and rebuild the patch; return immediately for other errors.

Learnt from: devantler
Repo: devantler-tech/platform
Timestamp: 2026-10-11T02:02:29.778Z
Learning: In scripts/maintain-longhorn-clients, legacyPublicationSafe permits capacity changes after a journal is restored and publication positively never started. This released path must retain claim/PV key and UID, all non-capacity specification fields including physical bindings, and Longhorn backing identity and data format. Deleted or replaced retained claims remain a hard stop. Interrupted recovery continues to require the original capacity.

Readiness at
This delivers the safety procedure, not the selector migration. The separate #4718 change and its protected maintenance, restoration and deployment readback remain required before #4197's node rollout. All four database clusters are currently Ready with their intended redundancy; today's partially failed backup is not being represented as a successful recovery point. |
Fresh delivery preflight on 11 October 2026 for reviewed head This is eligibility evidence, not an executed maintenance or rollout proof. No production resource was changed. The follow-on placement revision must still pass the protected all-volume detachment, client convergence, owned service restoration and separated health verification before the init-log node rollout can proceed. |
Why
Storage clients cannot reach some workers, leaving the init rollout blocked. Repairing their placement requires a controlled pause of storage-backed services without risking database recovery or backups.
What
Add a protected maintenance procedure that proves database health, pauses backup schedules, stops old reconciliation activity, and restores only pauses it owns. Keep the placement change separate so the safety procedure is deployed first.
Part of #4718
