Re: update-grub fails with multipath-tools (debian 6)

[alxgomz]

I get the very same issue trying to upgrade Lenny to squeeze with root
partition on SAN multipath'd device.

Found linux image: /boot/vmlinuz-2.6.26-2-xen-amd64
Found initrd image: /boot/initrd.img-2.6.26-2-xen-amd64
/usr/sbin/grub-probe: error: cannot find a GRUB drive for
/dev/mapper/mpath0-part1.  Check your device.map.
/usr/sbin/grub-probe: error: cannot find a GRUB drive for
/dev/mapper/mpath0-part1.  Check your device.map.

I almost have the same device.map as remi and my multipath configuration
differ a little as I have 2 HBA and 2 target devices so I have 4 underlying
devices fir each multipath device.

One of my workmate reported the Debian Installer fails at grub stage, so I
suspect this issue to be involved.

Debian ships with (GRUB) 1.98+20100804-14

Are later versions of grub supposed to fix this?
