Hi!
I’ve been using NixOS for 2 months now, and I have to say that I’m happy with the results so far coming from using Arch Linux. I have encounter, however, an issue after installing NixOS, and it is that NixOS was unable to mount a raid partition I created from 3 hard drivers when booting as it was assigned to /var.
On Reddit, I was told that the array needs to be automatically assemble by initramfs, but no details were given nor links to any documentation or Nix code examples. Furthermore, I dug NixOS documentation about Raid without any luck.
Running lsmod shows no sight of a raid kernel module that I can load, I think if I find one it should go into boot.kernelModules, but anyway, no sight of a raid module.
Here is my current system configuration:
# Edit this configuration file to define what should be installed on
# your system. Help is available in the configuration.nix(5) man page
# and in the NixOS manual (accessible by running ‘nixos-help’).
{ config, pkgs, ... }:
