I'm not sure is it available when %pre script runs, but anaconda does that somehow during the partitioning section so I guess it's possible. In the worst case scenario I would add reboot at the end of creation of raid config in the %pre script - so that it would reboot if change in config occured. I know that its rather a nasty hack, not a proper solution, but please keep in mind that anaconda has some limits. <div> Good luck! </div>Paul Malinowski <div> </div><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;"> <div style="font-family: arial,helvetica,sans-serif; font-size: 10pt;">----- Original Message ---- From: John Summerfield <debian@herakles.homelinux.org> To: Discussion list about Kickstart <kickstart-list@redhat.com> Sent: Thursday, 2 October, 2008 2:22:48 Subject: Re: Forcing a disk rescan after %pre Dag Wieers wrote: > Hi, > > We are integrating some pre-install scripts.

I'm a little puzzled. Years ago (RHL 7.x I think) I used to initialise disks in %pre with various incantations of dd and fdisk (one can pipe commands into fdisk). That worked fine, and I'm pretty sure I created new partitions. fdisk forces partition tables to be reread. Of course, it's possible anaconda has been broken since then:-) -- Cheers John -- spambait <a ymailto="mailto:1aaaaaaa@coco.merseine.nu" href="mailto:1aaaaaaa@coco.merseine.nu">1aaaaaaa@coco.merseine.nu</a> <a ymailto="mailto:Z1aaaaaaa@coco.merseine.nu" href="mailto:Z1aaaaaaa@coco.merseine.nu">Z1aaaaaaa@coco.merseine.nu</a> -- Advice <a href="http://webfoot.com/advice/email.top.php" target="_blank">http://webfoot.com/advice/email.top.php</a> <a href="http://www.catb.org/%7Eesr/faqs/smart-questions.html" target="_blank">http://www.catb.org/~esr/faqs/smart-questions.html</a> <a href="http://support.microsoft.com/kb/555375" target="_blank">http://support.microsoft.com/kb/555375</a> You cannot reply off-list:-) _______________________________________________ Kickstart-list mailing list <a ymailto="mailto:Kickstart-list@redhat.com" href="mailto:Kickstart-list@redhat.com">Kickstart-list@redhat.com</a> <a href="https://www.redhat.com/mailman/listinfo/kickstart-list" target="_blank">https://www.redhat.com/mailman/listinfo/kickstart-list</a> </div></div></div> </body></html>
