> {{org.apache.lucene.store.FSDirectory.open(Path, LockFactory)}} and {{org.apache.lucene.store.FSDirectory.open(Path)}} always assume the path is created on the default file system. If the path is not on the default file system {{MMapDirectory}} is the wrong choice as only the default file system can provide {{mmap()}}.
> In case of a non default file system {{SimpleFSDirectory}} is a good choice.
> See this bug for an example
