so i have 4x4 TB hdds which i'd like to merge. I created several folders on these hdds (movie,movie2,movie3 etc.). I then used unionfs to merge these 4 hdds under the share folder media. I filled those folder with some files. When I now try to access these files under the new created unionfs media folder I am not able to see these files . The folder is empty . Shouldn't I be able to see those files ?Where is my mistake ?
