nixos-anywhere fails during disko-formatting-step

[tristanRW]

Today I used nixos-anywhere to format and setup a system that has the following drives.

[root@homecloud:~]# lsblk

My disko config looks like this:

I will retry the installation using a nixos installer usb, and will not have time to resolve this issue myself.
Still I hope to bring it to attention, here so it can be fixed and not happen to others in the future.
From what I can gather the mdadm disk is not yet visible to the kernel after the formatting and the problem could be solved by introducing a reboot between formatting and setting up the raid (see the "Error" after writing the two ssd's).
