    Description

      The volume scanner/disk checker currently only checks filesystem permissions and directory existence. It should also do write, sync, and read back from a file as well to touch the actual hardware and not just information in the OS cache.

      Having more robust volume failure detection will be required when the container scanner is enabled, because we do not want to mark large amounts of containers unhealthy when the real problem is the disk.
