---------------------------------
Summary: FSO directory deletion over reports purge metrics when a
batch Ratis submit fails
Key: HDDS-16437
URL: https://issues.apache.org/jira/browse/HDDS-16437
Project: Apache Ozone
Issue Type: Bug
Reporter: Siyao Meng
h3. Finding
optimizeDirDeletesAndSubmitRequest discards the batching result and increments
deletion counters and operator metrics (numDirsSentForPurge, INFO log, AOS/snap
last-run metrics) for the full pre-batch list even when a later batch's Ratis
submit returns non-success, so only committed batches are durable while metrics
over-report; the drift is cumulative and never reconciled. The deletion itself
self-corrects via retry, no data corruption.
h3. Classification
* Verdict: REPRODUCED
* Severity: Medium
* Source: Specula TLA+ model checking and confirmation debate, finding CR-7
