I am copying a 'disk image' to an NFS mounted volume. I'm using: dd if=/dev/ad0 of=Disk.img After dd completes the number of blocks indicated is what the raw disk device should be. However, when I look at the NFS mounted image, the file size is anything but the 80 GB size it should be. I have not used NFS very much in the last few years, but I don't recall such data loss as being something to worry about. The NFS transactions, while using UDP, may be 'lost', but there was some form of retry and eventually the file data would be received, or ultimately the NFS client would emit some error message. Is there some option that I have not enabled in the kernel build, or well known problem that could be the reason for this behavior. Thanks, John Clark.
