Well, it looks like something is wrong with where you are trying to write the dump. What is mounted on /mnt/hd/FBSD? Is anything? Is there a filesystem built on it or is it some serial access media such as tape (in naming convention I have never seen). Or is FBSD a directory? If so, you have to name a file within it eg: /mnt/hd/FBSD/root.dump I don't specifically see any problem with your dump command. It is the media where you are writing that is causing your problem. It hasn't had a filesystem built or mounted on it or something like that. By the way, you don't have to specify the /dev/name in a dump. dump -0Lauf /mnt/hd/FBSD / would be sufficient and more clear to human read. dump -0Lauf /mnt/hd/FBSD/home.dump /home would be good for /home It is hard to guess beyond this what is happening. > P.S.:ad0s3a is my root directory (/) > s3b is /home and > s3d is my swap space Don't dump swap. ////jerry > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org" _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
