Command: grub2-install --recheck /dev/sda Results: Installing for i386-pc platform. grub2-install: warning: this GPT partition label contains no BIOS Boot Partition; embedding won't be possible. grub2-install: error: embedding is not possible, but this is required for RAID and LVM install.
To install grub2 for BIOS booting on GPT disk you need to do what error message tells you - create small BIOS Boot partition where grub2 core.img (analog of grub legacy stage1.5) is stored. This partition should not have any filesystem or be part of Linux MD RAID. It is small; 1MB is more than enough today; 10MB is likely enough for any foreseeable future. You can create this partition using parted or gdisk. You would need to have BIOS Boot partition on every disk you want to install bootloader. grub2 will have to be installed separately on each disk then. It makes sense to install bootloader on every disk that is part of RAID where /boot/grub2 is located, as long as BIOS can boot from each disk.
Command: grub2-install --recheck /dev/md0
That is going to work only if your Linux MD RAID is recognized by BIOS, which means it is actually fake RAID, not software RAID. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
