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

NixOs mit nativ encrypted zfs (uefi)

1. Download NixOs 18.03

2. Bootfähigen USB erstellen

3. Installation von NixOs starten

4. Mit nano in /etc/nixos/configuration.nix

   $ nano /etx/nixos/configuration.nix

folgendes einfügen (Reihenfolge entscheidend):

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

5. Laden der Packages

   $ nixos-rebuild switch

6. ZFS in den Kernel laden

   $ modprobe zfs

7. Partitionierung von /dev/sda mit gdisk oder fdisk:

   /dev/sda1 100MB code: ef00 (Boot-Partition)
   /dev/sda2 restliche Platte fstyp: solaris /home mit code: bf05 erhältlich (Pool)

8. 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

9.

   $ 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/home
   $ zfs create -o mountpoint=legacy zroot/root/nixos
   $ zfs set compression=lz4 zpool/pool/home 

10. Mount zroot/root/nixos nach /mnt

   $ mount -t zfs zroot/root/nixos /mnt

11. Unter /mnt die Ordner home, tmp und boot anlegen

   $ mkdir /mnt/{home,tmp,boot}

12. 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/

13. Die restlichen Verzeichnisse mounten

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

14. NixOs hardware-configuration.nix erzeugen

   $ nixos-generate-config  --root /mnt

Diese sollte so ähnlich aussehen:

     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";
     };

15. 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";

(15.1 Gegebenenfalls in dieser Datei die Zeile powerManagement auskommentieren)

16. nixos-install
