[jira] [Created] (HDDS-7788) Ratis OverReplicationHandler should exclude stale replicas

             Summary: Ratis OverReplicationHandler should exclude stale replicas
                 Key: HDDS-7788
                 URL: https://issues.apache.org/jira/browse/HDDS-7788
             Project: Apache Ozone
          Issue Type: Sub-task
          Components: SCM
            Reporter: Stephen O'Donnell
            Assignee: Stephen O'Donnell


As a stale DN is more than likely dead, in the RatisOverReplicationHandler we should exclude stale replicas before checking for over-replication. That way, we will not allow stale replicas to count toward over-replication. If we continue consider a stale replica as "present" for over-replication, we may remove another replica and then the stale one could go dead and get removed too, resulting in under replication.
