 |
|
I have root on a LVM volume and I used genkernel (which is supposed to be the greatest thing since sliced bread) to make the initramfs. After genkernel compiled the kernel I added the grub options manually (since genkernel borks up /boot/grub/grub.conf). When I try to boot into my install the kernel complains that /dev/system/root is not a valid root device despite the fact that it is. I compiled LVM built-in plus the drivers for my sata controller and my pata controller.
/boot/grub/grub.conf:
| Code: |
default 0
timeout 10
title Gentoo 2.6.27.8
root (hd0,1)
kernel /kernel-genkernel-x86_64-2.6.27.8 dolvm root=/dev/ram0 real_root=/dev/system/root vga=0x317
initrd /initramfs-genkernel-x86_64-2.6.27.8
title Windows XP Professional
rootnoverify (hd0,0)

I suspect I'm supposed to put "dolvm" on the initrd line. |

| Yes I did. When the kernel boots it says "Activating LVM volumes" then whines that /dev/system/root is not a valid block device. |

Did you make your genkernel kernel like this:
| Code: | | genkernel --lvm all |
or just the initrd with this command:
| Code: | | genkernel --lvm initrd |
i.e. did you use the "--lvm" option? |

You don't need "udev" anymore as that's on by default and you already have dolvm as a kernel param. |

I don't remember if I put the two hyphens before lvm but I did put all. I'll rebuild and make sure I put "--lvm" and not "lvm". |
