comment RAID6 mdraid -> LVM -> EXT4 root with GRUB2?
I have also reported this to Debian now. Let's see and hope the backport is trivial and propagates far (I'd also like to see this fixed on Ubuntu 8.04, 10.04, 12.04 and Debian 6).

comment RAID6 mdraid -> LVM -> EXT4 root with GRUB2?
My /boot is indeed on VG raid6 LV root. It does initially set the /usr partition as root, but then before actually trying to load the kernel, it uses LV root again for the root. I'll try to simply edit the grub.cfg by hand and if it works, I'll consider filing a bug against the generation script.

One grammar mistake fixed, added additional information and my grub.cfg file.

comment RAID6 mdraid -> LVM -> EXT4 root with GRUB2?
Negative. The system is still bootable and operates as expected when you boot into it from the debian-installer rescue mode (or appropriately chroot into it from ~any mdraid + LVM supporting livecd for that matter). A single disk LVM setup works. An mdraid RAID1 + LVM setup works too. Managing to boot from mdraid RAID6 + LVM is the issue at hand here. I am left dumbfounded by how to debug this further - memory snapshots of the RAM of the virtual machine do not seem viable since I do not know what exactly I'm hunting for here in the status of the GRUB2 binary either.

comment RAID6 mdraid -> LVM -> EXT4 root with GRUB2?
Negative. When stating ls from the GRUB2 rescue mode, it lists, amongst other things, (raid6), the LVM volume group and (raid6-root), the logical volume containing / and /boot for me. When trying to ls (raid6-root) it outputs a newline. So it does see the mdraid, it does manage to see the LVM setup, but it just cannot read the filesystem and I have no idea why.
