Thanks for the reply. I must have been thinking of ufsdump from solaris... I'm having another difficulty with dump on FreeBSD 4.2 though: the "nodump" flag is being ignored. Since I can't dump directories, and I need to dump /home/foo, I set `chflag nodump` to /home/*, and then removed "nodump" for /home/foo. Doing the same dump command I issue below simply ignores the nodump flags and tries to dump the whole /home fs. The same thing happens for different dump levels, and with '-h 1' or without the -h flag. Is the "nodump" flag a documented, but un-implemented feature? Thanks again, Brent On Mon, Oct 21, 2002 at 10:12:24PM -0400, Lowell Gilbert wrote: > Brent Kearney <brent@kearneys.ca> writes: > > > Hello, I'm trying the following on FreeBSD 4.2: > > > > dump -0 -h 0 -u -a -f /dev/nsa0 /home/foo > > > > And the dump is dying with the message: > > > > DUMP: Dumping /home/shared to /dev/nsa0 > > DUMP: bad sblock magic number > > DUMP: The ENTIRE dump is aborted. > > > > /home/foo is not a mount point, but I seem to remember FreeBSD's dump > > being able to dump subdirectories. > > The man page seems to say otherwise, so you're on your own there. > Luckily, you have the source. > > > I can dump /home (which is a mount > > point) without any errors, so its not a problem with /dev/nsa0.
