Node cloning

Hi all,
     I don't want to turn the beowulf group into the 'how best to clone
nodes' group, but before I started moving hardware around to clone a node,
I'd take a look at rsync: http://rsync.samba.org/.

my two cents, Rich

Hi Luca

I cloned 26 hard disk to setup our cluster

I didn't use the method described in the book "How to build a beowulf - A
guide to the implementation and application of PC clusters" (authors:
Sterling, Salmon, Becker, Savarese  Ed. MIT Press)
Basically because I don't have any floppy drive or CDROM drive on all those
nodes (except for the gateway)
So what I did was:
Configure ONE slave node
Install the configured hard drive on /dev/hda
Install three hard drives on hdb, hdc, and hdd
And then use the command (this will take long, so you can do it overnight)
         cp /dev/hda /dev/hdb ; cp /dev/hda /dev/hdc ; cp /dev/hda /dev/hdd

After that you can turn off the computer, install all the hard drive on
different machines, CHANGE the names and IP's and that's it
