>                 URL: https://issues.apache.org/jira/browse/HDFS-8871
>             Project: Hadoop HDFS
>          Issue Type: Bug
>    Affects Versions: 2.6.0
>            Reporter: Kihwal Lee
>            Assignee: Daryn Sharp
>            Priority: Critical

> Since staleness may not be properly cleared, a node with a failed volume may not actually
get scanned for block replication. Nothing is being replicated from these nodes.
> This bug does not manifest unless the datanode has a unique storage ID per volume.
