> Key: HDDS-15455
> URL: https://issues.apache.org/jira/browse/HDDS-15455
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Sreeja

> Implement logic to traverse all storage volumes configured in
> *{{hdds.datanode.dir}}* and discover container directories present under the
> DataNode container storage hierarchy.
> For each discovered container directory:
> * Extract the container ID from the directory name.
> * Collect the container directory path, storage volume, and directory size.
> * Determine the metadata status:
> ** {{*MISSING_METADATA*}} if {{metadata/\{containerId}.container}} does not
> exist.
> ** {{*INVALID_METADATA*}} if the metadata file exists but cannot be parsed,
> or if the container ID stored in the metadata does not match the
> directory-name container ID.
> ** *{{VALID}}* otherwise.
> Store the results as a mapping:
> {{containerId -> List<ContainerOccurrence>}}
> where each occurrence contains the container directory path, volume, size,
> and metadata status.
> Use this mapping to identify duplicate container directories by detecting
> container IDs associated with more than one on-disk occurrence across storage
> volumes on the same DataNode.
