> DiskChecker can fail to detect total disk/controller failures indefinitely.
> We have seen this in real clusters. DiskChecker performs simple
> permissions-based checks on directories which do not guarantee that any disk
> IO will be attempted.
> A simple improvement is to write some data and flush it to the disk.
