grep grub2-install /path/to/anaconda/logs/program.log
I forget if it accepts two devices on a line, or if it takes separate
commands. But
grub2-install /dev/sdX
grub2-install /dev/sdY
That will work on BIOS.
On UEFI this is totally fakaked right now as neither GRUB upstream nor
distros have a proper user friendly solution for this at all. CentOS
7's installer offers an improper user friendly solution which allows
you to RAID 1 the EFI System partitions with md raid.
On UEFI, I do a post-install alteration to make it something more
standard with the way upstream ought to be doing it. That means two
grub.cfg's: a generic one on the ESPs that merely forwards to
/boot/grub2/grub.cfg. That makes the ESP contents generic and never
modified again. And then the real grub.cfg is /boot/grub2/grub.cfg
which can of course then be on raid1 or raid 5 or whatever, and this
is the file that gets updated when there are kernel updates.
