kernel - Server drops to dracut debug shell after upgrading from Fedora 14 to 15 -
I have upgraded to Fedora 15 using the upgrade now. Specifically, I did
sudo yum update sudo yum install preupgrade sudo preupgrade-cli "Fedora 15 (Lovelock)" when to me Therefore, I have entered:
sudo reboot and waiting to complete the upgrade. My server now fails to reboot, leaving debug shell:
Debug is leaving shell shell: can not use TTI; Typing job control off: Typing in 'dmesg' gives me the following information (I have left everything but have the last two rows):
[8.574475] Dracula: Autosambling MD Red [29.531556] Draft Warning: No root device found "Block: / dev / disk / by-uuid / 812eb062-d765-4065-be34-4a2cf4160064" The system is installed on two S-ATAII HDs (RAID 1) and I can boot into the system by selecting the old Fedora 14 kernel (2.6.35.14-95.fc14.x86_64) in GRUB.

I will check what options you are sending from the kernel to GRUB. Specifically, what is the root = string on each of your kernel options? You can see what should be by typing UUID : mdadm --examine / dev / sda1 < / Pre> (It should work with dracut shell, if it is not, you might want to recreate your initrd ?) You can also try to pass the MD device name as a kernel boot option, so replace the grub option with some of the rows: kernel vmlinuz-2.6.42 ro root = / dev / md127
