has anyone succeeded in having /boot on a lvm volume, or a mdadm raid device, which grub2 can directly boot from it?

If yes please give me some advice how to do it, i want to add full grub2 support to archboot setup and the docs are quite messy. I haven't found a way to do such a setup.

I am using raid5 with grub2. And yes, documentation is rareso I probably solved it the stupid way. I couldn't create my raid on the bare drives like sda, sdb, sdc etc. as there wont be enough space for the grub2 boot loader. So I create one big partition on each drive and created a raid with sda1,sdb1 etc.. Then I was able to install the bootloader to each of those drives (sda, sdb etc.) Within the raid I have created the actual partitions; so this setup looks a little weird but totally works. My grub.cfg looks like this: set timeout=1 set default=0 insmod raid insmod raid5rec insmod mdraid insmod ext2 set root=(md0,1) menuentry "Arch Linux" { linux /boot/vmlinuz26 root=/dev/md0p1 ro initrd /boot/kernel26.img } Interesting is that I couldn't use labels here for the kernel root partition. (maybe its initcpio related and already fixed) And you might need to load those raid and mdraid modules and set the root to md0 instead of hd0 etc.. -- Pierre Schmitz, https://users.archlinux.de/~pierre
