> Enhance DataNodeSafeModeRule to Use Pipeline DN List
> ----------------------------------------------------
>
> Key: HDDS-11843
> URL: https://issues.apache.org/jira/browse/HDDS-11843
> Project: Apache Ozone
> Issue Type: Improvement
> Components: SCM
> Reporter: Shilun Fan
> Assignee: Shilun Fan
> Priority: Major
> Labels: pull-request-available
>
> Currently, the *DataNodeSafeModeRule* in SCM requires users to manually
> configure the number of DataNodes in the cluster using the setting
> {{{}hdds.scm.safemode.min.datanode{}}}, with a default value of 1. If not
> configured, this value defaults to 1. However, since clusters are frequently
> scaled and the number of active DataNodes is uncertain, relying on a fixed
> value to determine whether SafeMode conditions are met is not reliable.
> To address this issue, we propose a new rule: allowing *DataNodeSafeModeRule*
> to retrieve the DataNode list from the registered Pipeline and use a
> configurable ratio to dynamically calculate the required number of DataNodes.
> This will provide a more accurate way to determine when the system can exit
> SafeMode.
