I don't recall the details, but when I first set up tape spanning I ran into problems with system settings for shared memory segment size. This limited the maximum spanning chunk to some tiny amount and caused the number of chunks to go into the hundreds. As each chunk is a separate tape file, and the tape drive stops and restarts between each tape file, the result was just like a drive that was shoe-shining rather than streaming. Check your system and amanda logs for messages regarding shared mem. -- Jon H.
