Issue

  • When an object store is unmirrored in a FabricPool mirror configuration, ONTAP deletes the mirrored objects from the unmirrored S3 container.
  • If the same S3 container is reused to mirror the same FabricPool configuration before the ONTAP unmirror cleanup completes, the cleanup can also delete objects written by the new mirror.
  • If the affected mirror object store is then promoted to primary and the original primary object store is unmirrored, some objects may no longer be available.
  • Reads for those objects will fail with inconsistent user data blocks.
