Hello Jason, I'm in a similar situation. What happens for you is that the tape has reached the end (my guess; I get write errors when I reach end-of-tapes), and is trying to tell you this on the tty; "fopen on /dev/tty" means that it cannot talk to a console, probably because you're running it from cron, or detached the dump process from the tty. AFAIK, you can't run dump from cron, at least not directly. (I'd like to hear from you folks! How do you make automated dumps?) Dump needs user interaction when an error or end-of-tape occurs, or it will get suspended or fail. Hence, it must be started from a console. I guess one could make a script that runs on the console and sleeps during the day...? Or maybe let cron attach the dump command to a console (better, but how,and is it possible?). What does your dump command look like? If your tape can swallow no more than 2GB, you've reached the end-of-tape. Using the B option, yuo can tell dump about the tape lenght, and get "tape-end" instead of "write-error". If you expect hardware compression, are you sure it is switched on? Probably not?
