I lost a software striped (I know it was a bad idea) raid of three 1TB external drives. I have a 2TB external that I want to use to replace two of the drives lost and use another 1TB to get a 3TB pool using a union filesystem. However when I tried to recover the system none of the video (or any other file for that matter) would play. The file sizes are correct what do I need to do in order to gain access to my files again? Is it a argument that I need to feed to the snapraid fix?
