I believe I've cloned Linux RAIDs by simply using the linux "dd" command on
the raw RAID device (/dev/md0 for example). If I remember I set up at least
one drive of the target in RAID (say /dev/md1) and simply did the "dd
if=/dev/md0 of=/dev/md1 BS-1M" thing and let it rip. Of course you can do this
in knoppix (need to sudo into root permissions first).
The new drives will also need a boot loader on track zero (I typically just use
"install_mbr /dev/sdx", also from knoppix) for it to boot. I just did one
drive because once I got it done I used the proper "mdadm" options to add the
mirror drive to it. If the new drive partition ends up being bigger than the
original (typically the case), I just use the file system's resizing tools to
grow it out to the size of the drive. In knoppix there should be the nice GUI
front ends for this ("gparted", or KDE's "Partition Manager") that makes this a
snap!
