[Solved] Install / configure GRUB on LVM

bengbers · 2014-03-28 16:33:57

I've used the Beginners' Guide to install archlinux-2014.02.01-dual on a machine that already had LVM installed.

After renaming the physical and logical volumegroups, I could mount the logical volumes rootvol and home with 'mount /dev/arch/rootvol /mnt' and 'mount /dev/arch/home /mnt/home' (instead of using mount /dev/sda3/rootvol /mnt).

The installation procedures works fine but I can't manage to install the bootloader.

Where can I find instructions on how to install the bootloader on LVM?
Are there any changes I have to apply before I can begin with the instalation off the bootloader?

Ben

I'll try to describe what I did. To me it seems that arch is installed but the only failure is the installation of grub.

With gparted I set up /dev/sda1 as MBR (ext3)

I set up LVM as follows:
vgcreate /dev/arch/sda2
lvcreate -L 30GB -n rootvol /dev/arch
lvcreate -L 3.53GB -n swap /dev/arch
lvcreate -l 100%FREE -n home /dev/arch

mkswap /dev/arch/swap
swapon /dev/arch/swap
mkfs.ext4 /dev/arch/rootvol
mkfs.ext4 /dev/arch/home

mount /dev/arch/rootvol /mnt
mkdir /mnt/home
mkdir /mnt/boot
mount /dev/arch/home /mnt/home
mount /dev/sda1 /mnt/boot

pacstrap -i /mnt base base-devel grub-bios
genfstab -p -U /mnt >> /mnt/etc/fstab

arch-chroot /mnt
create locale
create vconsole.conf
create /etc/hostname
create localzone
set hwclock

nano /etc/mkinitcpio.conf
add lvm2 to HOOKS=" ... lvm2 filesystems ...."
mkinitcpio -p linux
grub-install /dev/sda

exit
umount -R /mnt
reboot

All this without errors
After rebooting a normal grub boot-screen popped up. But after a few seconds, when trying to boot arch-linux it said something like "can' t find linux core?"
And after trying to enter the grub rescue-mode, I am now stuck in the grub-prompt.

How can I exit the grub rescue-mode?
Do you see any errors in mu attempt to create grub-config?

Did you generate the grub configuration files? It's not mentioned above.

If you missed this step then you can boot from the install media and chroot into your new installation so you can run the command to generate the config.

As slithery said, you had to run grub-mkconfig again after the chages made in mkinitcpio.conf.

Next try (now with code-tags):

Install from boot-medium (DVD)

root@archiso ~ # mount /dev/arch/rootvol /mnt
root@archiso ~ # mount /dev/arch/home /mnt/home
root@archiso ~ # mount /dev/sda1 /mnt/boot

. pacstrap, genfstab, locale, vconsole and all that stuff can be skipped

root@archiso ~ # arch-chroot /mnt /bin/bash
[root@archiso /]# nano /etc/mkinitcpio.conf

HOOKS="base udev autodetect modconf block lvm2 filesystems keyboard fsck"

[root@archiso /]# mkinitcpio -p linux

No errors, but
==> WARNING: Possibly missing firmware for module aic94xx
==> WARNING: Possibly missing firmware for module smsmdtv

[root@archiso /]# grub-install /dev/sda
[root@archiso /]# grub-mkconfig -o /boot/grub/grub.cfg

WARNING: Failed to connect to lvmetad: No such file or directory. Falling back to internal scanning | This block repeated at least 4 times

done

[root@archiso /]# passwd
[root@archiso /]# exit
root@archiso ~ # umount -R /mnt
root@archiso ~#  reboot

Succes!
Conclusion, I must have missed the line [root@archiso /]# grub-mkconfig -o /boot/grub/grub.cfg
