The SCM configuration
ozone.scm.ec.pipeline.per.volume.factorhadTODOas its description, so the generatedozone-default.xmland the config docs did not explain what the property does.This PR replaces the placeholder with a description based on how the factor is used in
WritableECContainerProvider#getMaximumPipelines. For each EC replication config, SCM limits the number of open pipelines to:max(factor * total healthy volumes / (data + parity), ozone.scm.ec.pipeline.minimum)Setting the factor to 0 disables the volume-based limit, so only
ozone.scm.ec.pipeline.minimumapplies.This is a description-only change; there is no change in behavior.
