      Description

      Config servers require journaling to be on to support committed reads. If you try to specify --nojournal with --configsvr on the command line, we correctly error. If, however, you specify storage.journal.enabled:false in a config file along with sharing.clusterRole:configsvr, we allow it. This can cause all majority reads against the config servers to fail, rendering the cluster unusable.
