Hi Mark, 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 Daniel <div>On 1/24/06, Mark Hlawatschek <<a href="mailto:hlawatschek@atix.de">hlawatschek@atix.de</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">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 <a href="http://www.open-sharedroot.org">http://www.open-sharedroot.org</a> 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.
