kernel panic due to incorrect root partition
Hi all,
I had a SAS hard drive on a Red Hat Linux 7.3 machine and was using the kernel boot line- kernel /vmlinuz-2.4.30-ring-pae-aac-sam ro root=/dev/sda3 vga=extended panic=60 Now, I have replaced it with a SATA hard drive. When I try to boot, I get the following error messages- VFS: Please use a correct "root=" option Kernel Panic: Cannot mount root partition. Rebooting in 60 secs... During grub boot menu, I have tried editing the boot line by replacing "sda3" with "sdb3", "sdc3", "sdd3", "hda3", "hdb3", "hdc3" and "hdd3", but it didn't solve the problem. Is there a way for me to determine the root partition name? I'm running a Supermicro dual core box with Western Digital "Raptor" SATA 10k rpm hard drive. Thanks, Neelay.:scratch: |
Does your kernel have SATA support?

then run the grub binary.... I remember I got the same problem, almost the same that is... when recompiling a kernel and I dident reload lilo to my mbr... and it gave me a simplar problem "kernel panic VS: blah blah" well all I can say it try running the grub binary, it might help... |

I'm pretty sure that the kernel that came with RH7.3 did not have SATA support and that that is the cause of his problem. |

Did you build your redhat kernel with "bare.i"? |
Hi all,
thanks for your response... I have SATA support enabled, both in Linux Kernel and in BIOS. So it shouldn't be a problem. Is there a way for me to figure out what the root partition for my SATA drive is? I tried using Knoppix and Gentoo live CDs, but neither of them auto mounted my hard drive. -Neelay. |
