Looking to create a Software RAID 1 setup for your 2-disk server on Ubuntu Server 20.04?

Let's start with the basics: the official guide by Ubuntu (https://ubuntu.com/server/docs/install/storage) is outdated/wrong. And as of March 2021 it's possible that there's a bug as well with how the bios_grub partitions are created when using multiple disks.

Now on to the solution:

Select "Custom storage layout" when you reach the storage configuration step of the installer.
If the disks have existing partitions, click on each disk under AVAILABLE DEVICES and then select REFORMAT. This will (temporarily) wipe out the partitions.

Note: This is the guide for v 2.x.

For the v3, please follow this url: https://blog.csdn.net/sam_shan/article/details/80585240 Thanks @liy-cn for contributing.
