TSB 2025-820: Potential Data Integrity Issues Found in Ozone

Learn more about the details communicated in TSB-820.

Summary
The Cloudera Engineering team has identified the following data integrity issues with Apache Ozone (Ozone):
  1. In certain situations, handling of failure paths when recovering from disk hardware failures, disk full situations, or over-replication can result in the incorrect deletion of some storage containers on those disk(s). In rare cases, all replicas of the container can be affected, leading to the data within that container becoming unavailable. Under certain extreme conditions, permanent data loss could occur.

    Reference: CDPD-83416

  2. A bug in the snapshot deep cleaning service and the object deletion path can lead to potential missing blocks of a snapshot key. This can happen only for the keys that were deleted from the active object store after the snapshot was created.
