Hi folks, after some investigation I find out how actually to unpack initrd files and get the content. I search the internet and find this site. https://bugzilla.redhat.com/show_bug.cgi?id=996245 So in my opinion dmraid must be included in the /etc/dracut.conf file or the files in/etc/dracut.conf.d/. #snip Peter Trenholme 2013-08-12 16:48:58 EDT Well, that didn't work: dm and dmraid were there, but mdraid was not included. I tried adding it: $ grep -v '#' /etc/dracut.conf | grep -v '^[[:space:]]*$' add_dracutmodules+="dm dmraid" add_drivers+="mdraid" hostonly="yes" mdadmconf="yes" lvmconf="no" #end snip But I can't find any line with this content in the configuration files. The content of the SuSE files are in dracut_conf_file_1 and dracut_conf_file_2 Could that be the reason for the error? Greetings Gert
