> -----------------------------------------------------------------------
>
> Key: HDDS-5739
> URL: https://issues.apache.org/jira/browse/HDDS-5739
> Project: Apache Ozone
> Issue Type: Task
> Components: Ozone Client, Ozone Datanode
> Reporter: Aravindan Vijayan
> Assignee: Zita Dombi
> Priority: Major
> Attachments: CLI based checker for Ozone Block corruption.pdf
>
>
> To help triage data corruption issues better, it would be good to have a CLI
> tool that attempts to read data from all block replicas and downloads copies
> of the file along with information on which file consists of which block
> replicas. This would help us understand which replica(s) is(are) problematic.
> Since keys can contain multiple blocks, we need to come with a mechanism of
> choosing a unique set of block replicas to construct a file as possible. When
> the implementation details are fully hashed out in this task, description
> will be updated.
