Hi, i installed the latest dracut version, removed this line from the systemd.conf DefaultTimeoutStartSec=300s and I re-run mkinitrd After i rebooted and repeated the same test I described in my post on 2014-11-10. (the vm i used today was exactly the same) All worked as expected, the only thing i noticed is that the boot (in both cases) require a very long time (some minutes more than normal). The only open question now is why the yast installer is not able to install grub on both the raid members while installing. (see the duplicated bug here: https://bugzilla.novell.com/show_bug.cgi?id=811830) Thank you all!
