foo rund um die Installation

ZFS

Neben

  boot.supportedFilesystems = [ "zfs" ];

muss wohl auch noch

  networking.hostId = "ac174b52";

angegeben werden. Das ist für solaris porting layer spl.

running unstable

  boot.zfs.enableUnstable = true;

nixos mit zfs (uefi)

1. Folgende Zeile, der configuration.nix des livesystems hinzufuegen:

boot.supportedFilesystems = [ "zfs" ];

2. nixos-rebuild switch

3. nano /etc/nixos/configuration.nix 3.1 configuration.nix hinzufuegen:

        boot.supportedFilesystems = [ "zfs" ];

4. nixos-rebuild switch

5. modprobe zfs

6. Partitionierung mit gdisk von sda:

  6.1 sda1 100MB boot partition mit code ef00
  6.2 sda2 restliche Platte eine Partition fstyp solaris /home (bf05)

7. zpool create -o ashift=12 -o altroot=/mnt rpool /dev/sda2

8. zfs create -o mountpoint=none rpool/root

9. zfs create -o mountpoint=legacy rpool/root/nixos

10. zfs create -o mountpoint=legacy rpool/home

11. zfs set compression=lz4 rpool/home

12. mount -t zfs rpool/root/nixos /mnt

13. mkdir /mnt/home

14. mount -t zfs rpool/home /mnt/home

15. mkfs.vfat /dev/sda1

16. mkdir mnt/boot

17. mount /dev/disk/by-id/"festplattenname"-part1 /mnt/boot

18. nixos-generate-config --root /mnt

19. nano /mnt/etc/nixos/hardware-configuration.nix

    19.1 sollte enthalten:

 fileSystems."/" =
   { device = "rpool/root/nixos";
     fsType = "zfs";
   };

 fileSystems."/home" =
   { device = "rpool/home";
     fsType = "zfs";
   };

 fileSystems."/boot" =
   { device = "/dev/disk/by-uuid/...";
     fsType = "vfat";
   };

20. nano /mnt/etc/nixos/configuration.nix

   20.1 das einfuegen:
         boot.supportedFilesystems = [ "zfs" ];
         networking.hostId = "ac174b52";

21. nixos-install

Durchführung einer erfolgreichen Installation mit ZFS mit nativer Verschlüsslung

etwa beispielsweise für UEFI

Herunterladen des Abbildes (iso) von NixOS unstable (18.03)

Erstellen eines Speichers (USB-Stick) von dem gestartet werden kann

Starten vom erstellten Speicher für die Installation von NixOS

Änderung der Konfiguration für die Verwendung von ZFS in der (zentralen) Datei zur Verwaltung von NixOS (für den laufenden Betrieb)

nano /etc/nixos/configuration.nix

{ config, pkgs, ... }:

{
  imports = [ <nixpkgs/nixos/modules/installer/cd-dvd/installation-cd-graphical-kde.nix> ];

	boot.zfs.enableUnstable = true;
	boot.supportedFilesystems = [ "zfs" ];

}

Anwenden der geänderten Konfigutation von NixOS (für den laufenden Betrieb)

nixos-rebuild switch

Hinzufügen des Moduls vom Kernel für die Verwendung von ZFS (für den laufenden Betrieb)

modprobe zfs

Partitionieren des Massenspeichers des Ziels der Installation

• von /dev/sda
• beispielsweise mit gdisk oder fdisk

Üblicher Weise ist der Massenspeicher /dev/sda. Aber der Massenspeicher kann auch /dev/sdb oder anderes nachfolgendes Gerät sein, etwa wenn der Speicher von dem die Installation gestartet wurde /dev/sda ist.

Partitionieren eines Teils für das Booten (efi)

/dev/sda1 100MB code: ef00 (Boot-Partition)

Partitionieren eines Teils (restlichen) für alle anderen Daten (außer für das Booten (efi)) mit ZFS

/dev/sda2 restliche Platte fstyp: solaris /home mit code: bf05 erhältlich (Pool)

Vollständig encrypted Pool anlegen (zroot kann auch anders benannt werden, ashift=12 für 4k Blocksize)

zpool create -o ashift=12 -o altroot="/mnt" -O encryption=aes-256-gcm -O keyformat=passphrase zroot /dev/sda2

Erstellen der Datasets für ZFS

zfs create -o mountpoint=none zroot/root

zfs create -o mountpoint=legacy -o sync=disabled zroot/root/tmp

zfs create -o mountpoint=legacy zroot/root/nixos

zfs create -o mountpoint=legacy zroot/root/home

zfs set compression=lz4 zroot/root/home

Einhängen vom Dataset für ZFS, wo das Betriebssystem NixOS abgelegt sein soll, als Teil vom Ziel der Installation

mount -t zfs zroot/root/nixos /mnt

Unter /mnt die Ordner home, tmp und boot anlegen

mkdir /mnt/{home,tmp,boot}

Dateisystem (vfat) für die Boot-Partition /dev/sda1 festlegen und Mount von /dev/sda1 nach /mnt/boot

mkfs.vfat /dev/sda1

mount /dev/sda1 /mnt/boot/

Die restlichen Verzeichnisse mounten

mount -t zfs zroot/root/home /mnt/home/

mount -t zfs zroot/root/tmp /mnt/tmp/

NixOs hardware-configuration.nix erzeugen

nixos-generate-config --root /mnt

Diese sollte so ähnlich aussehen

cat /mnt/etc/nixos/hardware-configuration.nix

      fileSystems."/" =
      { device = "zpool/root/nixos";
        fsType = "zfs";
      };

    fileSystems."/home" =
      { device = "zpool/root/home";
        fsType = "zfs";
      };

    fileSystems."/tmp" =
      { device = "zpool/root/tmp";
        fsType = "zfs";
      };

    fileSystems."/boot" =
      { device = "/dev/disk/by-uuid/...";
        fsType = "vfat";
      };

Zum Schluss die configuration.nix im neuen System anpassen unter /mnt/etc/nixos/configuration.nix

nano /mnt/etc/nixos/configuration.nix

folgende Zeilen einfügen (Reihenfolge entscheidend)

    boot.zfs.enableUnstable = true;
    boot.supportedFilesystems = [ "zfs" ];
    networking.hostId = "ac174b52";

Gegebenenfalls in dieser Datei die Zeile powerManagement auskommentieren

Starten des Durchführens der Installation

nixos-install

Durchführung einer Installation mit ZFS mit nativer Verschlüsslung als Spiegel

Herunterladen des Abbildes (iso) von NixOS unstable (18.03)

Erstellen eines Speichers (USB-Stick) von dem gestartet werden kann

Starten vom erstellten Speicher für die Installation von NixOS

Änderung der Konfiguration für die Verwendung von ZFS in der (zentralen) Datei zur Verwaltung von NixOS (für den laufenden Betrieb)

}

Anwenden der geänderten Konfigutation von NixOS (für den laufenden Betrieb)

nixos-rebuild switch

Hinzufügen des Moduls vom Kernel für die Verwendung von ZFS (für den laufenden Betrieb)

Prüfen, on das Modul vom Kernel für die Verwendung von ZFS geladen ist

kmod list | grep zfs

modprobe zfs
