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Let's start with the basics: the official guide by Ubuntu (https://ubuntu.com/server/docs/install/storage) is outdated/wrong.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.

Download the RKN list from https://github.com/zapret-info/z-i, massage it into
a Mikrotik script that manages a firewall address list, and put it up on a web
server.  Note well that the list is gigantic---more than 80,000 entries as of
2018-04-28---so be sure to check if your router can handle it in advance (for
example, hAP Lite, with its measly 32M of memory, can’t).

On the router side, do something like

    /tool fetch url="https://sheaf.site/rkn.rsc" dst-path=rkn.rsc
    :import rkn.src
