Initialization leads to Access Denied on Windows

[williamb1024]

The fsync operations performed in the code referenced below always result in an access denied result when performed on a Windows OS.

raft-wal/metadb/metadb.go

Lines 135 to 145 in cc4505d

	// And Fsync that parent dir to make sure the new new file with it's new name
	// is persisted!
	dirF, err := os.Open(dir)
	if err != nil {
	return err
	}
	err = dirF.Sync()
	closeErr := dirF.Close()
	if err != nil {
	return err
	}

Additional use of Sync on a directory:

raft-wal/fs/fs.go

Lines 117 to 127 in cc4505d

	func syncDir(dir string) error {
	f, err := os.Open(dir)
	if err != nil {
	return err
	}
	err = f.Sync()
	closeErr := f.Close()
	if err != nil {
	return err
	}
	return closeErr
