In the past when Ive had 2 disks in a RAID1 mirror Ive been able
replicated the MBR on both such that the system is capable of booting
from either in the event of a failure using the command
dpkg-reconfigure grub-pc which then allowed both disks to be selected.
I was under the impression the equivalent for EFI/GPT systems was
dpkg-reconfigure grub-efi-amd64 however this does not give any option to
select multiple disks.
How can I ensure that the system is capable of booting from either
remaining disk in the event of a failure?
Many thanks
Andrew
