Repair Elasticsearch ILM Rollover Alias Stall

Repair Elasticsearch ILM Rollover Alias Stall — EVIDENCE-LIMITED REVIEW

Scenario received

Time series indexes stop rolling over after a template update changes the write alias.

Evidence inventory

• S1: index lifecycle policy history — partial extract described by the requester; original full source not provided here.
• S2: alias assignments — partial extract described by the requester; original full source not provided here.
• S3: rollover explain output — NOT PROVIDED; required to validate dependent findings.
• S4: index creation templates — NOT PROVIDED; required to validate dependent findings.

Case-specific checks

Compare write alias targets. INCOMPLETE until matching source anchors can be examined; document the observable facts, counterexamples and decision gate.
2.

Trace policy attachment lineage. INCOMPLETE until matching source anchors can be examined; document the observable facts, counterexamples and decision gate.
3.

Inspect rollover condition fulfillment. INCOMPLETE until matching source anchors can be examined; document the observable facts, counterexamples and decision gate.
4.

Test safe rollover on staging data. INCOMPLETE until matching source anchors can be examined; document the observable facts, counterexamples and decision gate.

Deliverables

Rollover stall explanation. Create an evidence-linked section with observations, missing data, owner and next validation step.

Alias repair proposal. Create an evidence-linked section with observations, missing data, owner and next validation step.

Index continuity test matrix. Create an evidence-linked section with observations, missing data, owner and next validation step.

Acceptance gate

The fix preserves index searchability and does not delete historical indices. Do not label this gate passed until supplied source records actually demonstrate it.

Verdict and next action

INCOMPLETE — evidence required. Request S3 and S4 from the authorized owner, reconcile them with S1 and S2, then repeat the four checks and log remaining conflicts. No production change, approval, communication, or test run is claimed.
