This also happens - at the end of the 8GB spool file Bacula stops writing to the tape and starts a new spool file, however this is not what I am having a problem with (at least not yet!) My issue is that while writing the spool file to tape, the tape stops and starts frequently. The spool file is 8GB, and the tape stops, rewinds, and restarts approximately 8-10 times during each despool operation. This is definitely shoe-shining, as the despool operation is supposed to happen in a single pass, with no stopping or rewinding until each despool has finished. After despooling has finished the drive is idle until the next despooling operation but this is expected. Because my spool file is 8GB, the drive should only stop writing after each 8GB of data, but it seems to stop more like every 1GB of data. I did not expect the drive to shoe-shine many times during the same despool operation. Do you have any idea why this might be happening?
