Hello;
I've a fully functional basic install ( kernel 2.6.17 on a Netra T105 (stripped, working like a charm) on a Netra T105
I'm so happy with the result and also to save some time I would to like it to clone it to another 5 Netra 105 with the exact config.
I' ve also connected a T130 on the "Mother-Netra" with free slots.

My idea would be to put the HD of the other Netra's in the T130 and the try to clone te SDA1 to SDA6 ( 1 HD ) to the new sun labeled HD ( exact the same HD). What would be the following step after creating and mounting the partitions?

If that could succeed I could emerge a mailserver onto the first, squid on the other, webserver,.....

Has somebody an idea how it could be done??
Thanks in Advance.

eventhorizon,

If you can put the two drives into the same machine that you can use dd to make a compete image of one drive on the other.
Neither drive needs to have anything mounted - the target drive need not even be formatted as *everything* will be copied, including empty space.

The command is
Code:
 dd if=/dev/sd<?> of=/dev/sd<?>
be sure to get the input and output files the right way round as there is no safety net.

The dd trick is okay, but I should mention that it is exceptionally important to create a backup (safety net) of anything you do in case of Murphy's Law rearing it's ugly head.

Toward that end, try:

Besides, doing a dd from a live filesystem is likely to introduce problems into the target fs. The safer way to use "dd" is to boot from a Gentoo livecd and then copy from inactive drive to inactive drive.

With programs like g4l, you now have an image you can go back to. Safer and better efficiency all around.

Cheers
