and then I said:
} you may have a old dump. The problem with the old dump is that it used
} longs in the lseek offset instead of using the off_t in the lseek offset.
}
} This will only give you the above error messages if you partition is greater
} that 2 GB.
}
} you can either get the /usr/src/sbin/dump/traverse.c from the FreeBSD 2.1.0
} distribution, or go in with an editor and change the blkn in the lseek()
} to: (off_t)blkno
the off_t was always there, I meant to say, take lines that look like:
if ((int)lseek(diskfd, ((off_t)blkno << dev_bshift), 0) < 0)
and turn them into lines that look like:
if (lseek(diskfd, ((off_t)blkno << dev_bshift), 0) == (off_t) -1)
--"earth calling" mark.
