[Solved] Grub-mkconfig says No Volume Groups found

Hi all,

I recently installed Ubuntu 12.04 in my other hard drive, and when I tried to update grub in the harddisk containing Arch (both harddisks are internal), I got the below error/warning.

[root@archblacky blacky]# grub-mkconfig -o /boot/grub/grub.cfg
Generating grub.cfg ...
Found linux image: /boot/vmlinuz-linux
Found initrd image: /boot/initramfs-linux.img
  /dev/mapper/control: open failed: No such device
  Failure to communicate with kernel device-mapper driver.
  Check that device-mapper is available in the kernel.
  No volume groups found
Found Microsoft Windows XP Professional on /dev/sda2
Found Ubuntu 12.04 LTS (12.04) on /dev/sdb1
done

What does this mean? Should I be worried? or should I install something?

I've not yet rebooted, afraid that I may not be able to reboot.

Thanks for your inputs!

Actually you're OK with your grub configuration, it already found ArchLinux, Windows XP and ubuntu 12.04 on the first partition of your secondary hard drive.

You don't need volume groups identification if you don't handle LVM, but if you wish to get rid of that message just load the device mapper module:

modprobe dm-mod

I don't want to start any additional modules so, if the above message is not an issue then I'm fine with this.

Thanks for the quick reply!

[Update] I rebooted my system and there were no issues, so I'm marking this as Solved now.
