> h2. Pipeline Rule with configurable percentage of pipelines with at least one
> datanode reported:
> In this rule we consider when at least 90% of pipelines have at least one
> datanode reported.
>
> This rule satisfies, when we exit chill mode, Ozone clients will have at
> least one open replica for reads to succeed. (We can increase this threshold
> default from 90%, if we want to see fewer failures during reads after exit
> chill mode.
