Re: grub2 /boot on lvm on ubuntu - incorrect magic number

[Cameron Braid]

Is this a bug in grub2 .. i.e. should I submit a bug with the grub2 bugtracker, or should I chase this up with some LVM people ?

Cheers

I thought that the install_device argument to grub-install had to be a harddisk (to use the MBR) or a partition in which the grub image was installed.  And I thought that grub detects the abstraction based on what /boot points to.

From looking at the GRUB 1.96 sources, I get the impression that this command line should be:

$ sudo grub-install /dev/mapper/Ubuntu-hardy64

in order for grub-probe to see the abstraction as GRUB_DEV_ABSTRACTION_LVM.

I could be majorly wrong, and this may have changed between 1.96 and the version that Cameron is using, but... I'm just trying to figure out how GRUB works. :^)
