I have a brand new installation that I'm trying to install Grub2 onto 6 disks, in a Linux Software Raid 5 array. I am using mdadm to build the array. I would think the correct partition to install grub2 on would be md0, but it fails to install, there. I created a /boot partition that goes to /md0p4, but it won't install there, either. I followed several forum posts and guides on how to install grub, but nothing works. I can't install it to the root of every /dev/sdx. One forum post said that Grub2 should have no issues with SW Raid. There aren't really any topics that help, here. Does anyone know anything about installing grub2 on software linux RAID 5?
