I attempted to upgrade my main workstation to Fedora Core 6 this weekend.
The upgrade itself went smoothly enough – I think. The new packages appear to be installed…
There’s just the small matter of being able to boot the thing. I’ve got a Linux Software RAID system. All of the partitions are RAID 1 on SATA. I’ve got /dev/md0 as the /boot partition, and /dev/md3 as /, /dev/md6 as /home, etc. – point being, it’s all RAID, see?
I remember this being a pain back in FC3 days, but I managed to get it working by installing GRUB on the MBR of both disks. This time, no dice.
If I boot into a rescue mode from the FC6 DVD, I can run grub:
grub> find /grub/stage1
grub> device (hd1) /dev/sda
grub> root (hd1,0)
grub> setup (hd1)
This all works. Unfortunately, on boot, I find that it won’t find the kernel image.
I’ve edited grub.conf and told it that root=/dev/md3. Interestingly, on booting without the DVD, hd(0,0) is really the first SATA device, so I edited grub.conf to use fully-qualified paths to the boot graphic and kernel file – I know this got me further, as I started seeing the FC6 graphic GRUB screen when the machine started. However, I still get an error 15 (file not found) when it tries to load the kernel.
Gaaah. I hate GRUB. Why doesn’t this just work? I spent an hour twiddling with options on Saturday, but right now, I just can’t get anywhere 😦
Thanks to Kelly for the inspiration for the title of this post…
