      Description

      The minimum number of non-faulty volumes to keep the DN active is hard-coded to 1. It would be useful to allow users to configure this value so the DN can be taken offline when eg half of its disks fail, otherwise it doesn't get reported until it's down to it's final disk and suffering degraded performance.
