|
|
I'm having troubles booting form a SCSI RAID 5 array.
When booting, it decompresses the kernel (which also resides on the array), but halfway the boot process, I get following messages:
Code: | VFS: Cannot open root device "ida/disc0/part3" or 00:00
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 00:00 |
I'm using Grub to boot, and since it is able to find the kernel image, I assume there's nothing wrong with the RAID, but mearly the part I need to pass as "root=".
I'm using /dev/ida/disc0/part3, since that is the disc/partition when I'm booting from the LiveCD. Anyone knows what I need to put there in order to be able to boot? |

Hi, I already installed Grub (indeed using the stage2 parameter), but as it is able to boot the kernel image (which panics), I assume that Grub has been installed correctly, and that It's mearly the root= parameter I need to get right in grub.conf |
