On clusterized environment, I create a file that doesn't belong in a specific DFS share path, such as Image-1_test.jpg at:

/mnt/ezdfs/var/ezdemo_site/storage/images/news/image1/234-1-eng-GB/

(which means this file was not created by creating a content via ezpublish, and therefore it is not registered in the database).
If I run the command:

sudo -u www-data php bin/php/dfscleanup.php -B -D

which is supposed to expunge these files, they are not removed.
