StorageGRID 11.5 or later

Answer

  • During the upgrade, the ingest object size could be less than 1 MB, resulting in the ILM rule for using the EC profile not being applied.
  • As a result, ingestion occurred according to the replicated copies for objects smaller than 1 MB.
  • Alerts are generated when ingestions occur, and the ILM rule is not fulfilled, however, the ILM rule for the EC profile was not checked due to the smaller object size.
  • Consequently, no alerts were generated for the site during the upgrade.
  • The Audit-Explain tool can be used to check the object size in bytes during the upgrade timeframe.
