Try man dd. dd will copy the disk verbatim, so assuming they're the same this will be a quick (and really, really dirty) way to do it. If they are not the same, then you can use a dump/restore (via a pipe, no need to actually STORE things) or a tar copy (again, via a pipe). You'd have to partition first tho'. /Kevin -- Kevin J.

If both drives are of the same size, simply do: dd if=/dev/hda of=/dev/hdc This will exactly duplicate everything, including partition tables, from master on primary (hda) to master on secondary (hdc).

The resulting disk when installed in the new system does not boot, so I set the bootable patron from Fdisk and the system is fully replicated. All program files settings work. Is there any such DISKDUMP facility from hda to hdb in LINUX? There are several different ways to do this. If the partitions are the same size, the 'dd' command usually works best: dd if=/dev/hda1 of=/dev/hdb1 dd if=/dev/hda2 of=/dev/hdb2 "if" means "in file" "of" means "out file", in this case the devices you want to copy from/to. There are several other options, see the "man dd" command for more info. Another way, much better for different size partitions, is to use "cp -a /usr /mnt/disk" or "cp -av /usr /mnt/disk" Throwing the "v" in causes every file to be printed out as it is copied, possibly slowing things down a bit depending on your display speed but shows you what's going on. Keep in mind that if a directory called "/usr" doesn't exist, it will be created on your mount point. If you don't want this, cd into the directory you want to copy then do "cp -a . /mnt/disk/" You can use the "x" option to keep the cp on one file system if you are moving your system, for example if you have /usr mounted on a separate filesystem from / and don't want to copy it all at once, "cp -avx / /mnt/disk/" would copy everything residing on the / partition to /mnt/dsisk. The important thing here is that the mount points themselves will not be created.../mnt/disk/usr or /mnt/disk/mnt/disk would have to be created in order to have a working system afterward. Another thing to be careful of is "cp -a / /mnt/disk" You will recurse into /mnt/disk and end up with /mnt/disk/mnt/disk/mnt/disk... ... until the destination parttion runs out of space. The last step in either process is to mount the root filesysem somewhere and do /mnt/disk/sbin/lilo -r /mnt/disk after changing /mnt/disk/lilo.conf to update the boot line in lilo.conf. The best thing to do is make a boot floppy if you're physically changing anything...it's a bit tricky getting lilo to work on hdb if you are going to move it to hda, for example...it's better to setup a boot floppy with your new root partition then run lilo once you've booted from there. -dwild

Please Help. This is a major bottleneck for me.
many solutions:
- make an install on drive hdb, then either
1. dd if=/dev/hdb of=/dev/hdc
2. dd if=/dev/hdb of=/dev/hdc count=1 ; kernel_reread /dev/hdc ;
mke2fs /dev/hdc1 ; mount /dev/hdb1 /source ; mount /dev/hdc1 /dest ; cp -a
/source /dest
- try the oem feature
3. - burn a cd out of *latest* cooker
- boot on it telling "oem" to syslinux
!! it will destroy every data on the harddrive !!
- you now have a very automated install matrix
(duplicate it with "dd if=/dev/hdb of=/dev/hdc bs=1M count=730")
put the harddrive in the oem box, the user will now have an *very* automated
install, just asking the root password and user password.
4. (just like 3. without burning a cd, doing the first part by hand)
have a look at the /etc/oem script on the rescue and do it by hand...
cu Pixel.
comments:
1. maybe copy unnecessary things - take too long
solution - use bs=8k count=
2. kernel_reread can be found on the new rescue, source is also at end of this
mail. This solution works with one partition. Can be easily enhanced to many
primary partitions... For extended partitions, more complicated, but not much :)
3. has just been added in latest cooker. It may still have some pb. The main
current limitation is IDE only, though it can be fixed easily for special cases.
#include stdio.h
#include sys/mount.h
#include fcntl.h
void die(char *msg)
{
perror(msg);
exit(1);
}
void kernel_read(char *dev)
{
int fd;
if ((fd = open(dev, O_RDONLY)) == -1) die("can't open device");
ioctl(fd, BLKRRPART, 0);
close(fd);
}
int main(int argc, char **argv)
{
if (argc != 2) {
fprintf(stderr, "usage: kernel_read_part hard drive device\n");
exit(1);
}
kernel_read(argv[1]);
}
Re: [Cooker] How to Disk Copy a full Installation?
The best is Kickstart, but when it is not possible to use it (too different machines, distro w/o Kickstart) I do more or less the following: Prepare the copying: - Install one machine completely and make a boot disk for it - Connect the installed machine to your local network Do this for every copy copy: - Connect a second PC with blank HD to your network - Boot the machine with a rescue CD (CD of MDK 7.1, or SuSE, or some of these credit-card rescue CDs which you get on every Linux fair. - partition the harddisk with 'fdisk' and format it with 'mkfs' and 'mkswap'. - Make it known for the first machine by entering it in roots .rhosts, /etc/hosts and /etc/hosts.equiv - Get access to the network entering hostname [your hostname] ifconfig eth0 inet [your IP] netmask [your netmask] route add default gw [your gateway IP] - Test the access with 'netstat -nr', 'ping [IP of first PC]' - Make mountpoints and mount all disk partitions, so that the later root directory will be /mnt. - Copy the 'root' partition cd /mnt rsh [IP of first PC] '(tar -cvplf - /)' | tar -xvpf - - Copy the other partitions cd /mnt rsh [IP of first PC] '(cd / ; tar -cvplf - usr)' | tar -xvpf - cd /mnt/usr rsh [IP of first PC] '(cd /usr ; tar -cvplf - local)' | tar -xvpf - cd .. - Adapt the configuration files (they are in /mnt/etc/... now) and edit /mnt/etc/inittab to start in a non-graphical run mode. - Boot the PC with the boot disk of the first PC, ignore all error messages. - Edit /etc/lilo.conf end enter 'lilo' to make the PC bootable. - Configure sound, graphics, network, printers, and so on with the Maandrake tools. - Boot the PC and all should work.

Re: [Cooker] How to Disk Copy a full Installation?
What about chooisng expert install and allowing it to create an autoinstall floppy? I have to re-format and re-install cooker every time I want to do clean testing. I use the autoinstall floppy (in RH known as kickstart) about 4-5 times per day. -Chris On Thu, 13 Jul 2000, Link World wrote: I am a system OEM in Bangalore,India selling systems bundled with Mandrake Linux.
