Thanks for your prompt reply, I went to your website already, almost all is in german.
From the slides I can see that shared-root can do the job for me. Next week will be good, but I have few time left for my project., but This weekend is already dead line for me.
Thanks for your help

Hi Daniel,
we are going to provide the HowTo and the required software to build up a GFS
shared root cluster within the next week. You will find everything you need
at http://www.open-sharedroot.org
The main part of the process is to build an initrd that mounts the shared
root. This is quite a complex thing to do. Therefore, we developed some
scripts to do the job. Keep looking at the website ...
Yes, you can use RHEL4 Update2 with open-sharedroot.
Regards,
Mark
