use /dev/sda only and when its installed you write it to sdb, too

dev/sda

The solution is continue without GRUB configure and then this command in shell on root user:

grub-install.real /dev/sda1
grub-install.real /dev/sdb1
grub-install.real /dev/md2
update-grub

The similar solution https://forum.proxmox.com/threads/problem-with-grub-upgrading-pve-6-4-15.115376/
