Hi everybody, I wanted to share the solution to a problem I had today...

I had one of my computers unable to boot, after a software upgrade followed by reboot. Dracut was complaining about things, the message looked something like

no root device "block:/dev/mapper/volgroup-lv_root" found

then dropped to some very useless shell. I followed the advice on this page about changing grub params, but it never got me anywhere. Using a bootable USB key with fedora, I couldn't even mount the boot partition, in my case /dev/sda1. The error was something like "partition busy or already mounted". That's what finally let me to my solution. Somebody else with the same problem online used this command (in my case run from the USB key fedora)

dmraid -r -E

and the computer just magically rebooted fine! Presumably a yum upgrade on dmraid was the cause of the problem, and it had nothing to do with dracut... My machine does have RAID disks, this solution is obviously only relevant to people with RAID. I thought I'd share this in case other people had the same problem.

How do you remove rhgb and quiet with grub2? /boot/grub2/grub.cfg is automatically generated. How do you get it out of the automatically generated file?Jrincayc 03:30, 23 November 2011 (UTC)

I figured out that the rhgb and quiet are now stored in /etc/default/grub, but I am not sure how to regenerate /boot/grub2/grub.cfg after /etc/default/grub is changed. Jrincayc 17:07, 24 November 2011 (UTC)
