I'm also seeing this using Bacula 2.0.1 on RHEL-4 with a jukebox holding two LTO-3 drives. It's an intermittent problem that I haven't been able to reproduce reliably, so I haven't opened a bug report on it yet. > Usually these errors happen in two situations: Let me add a third: when a job terminates with a "Fatal" error (those with a job status code of 'f'), rather than the more common "Error" error (those with a job status of 'E'). Here's my situation: I'm backing up both servers and laptops using the same hardware and software, but with different tape pools. The servers never encounter this failure condition; it happens to the laptops about once every week or two. After watching the situation for a while, it seems that the failure pattern is that these file mismatch errors always occur after a fatal client error, which in turn is caused when a job begins, writes some data to tape, and is then unable to continue because the client machine has been shut down or taken off the network. > When the tape is not properly "finished" by Bacula, for example because > of a catalog, SD or DIR crash, or when you restart your Bacula server > while jobs are running.
