I cant install Grub on a Fresh 18.04 alternate server Raid 1 installation.

I already tryed it 2 times and grub cant be installed, no matter which volume i try.

I use 2 physical volumes 4TB for Raid 1 and i created /boot /swap and /home INTO the Raid 1. The raid 1 volume is using all space because i want it mirrored complete....

  • Is there an error message when you run sudo grub-install /dev/<your-device>?

Its solved. I needed to set up a little 100MB grub-bios partition by installing on both drives.
