 SigmaSquadron | Hi all. Is there a way to create a partitionless LUKS device with Disko? All of the examples in the repo are putting the LUKS volume inside a GPT partition table, but since the LUKS volume will take up my entire disk, I would prefer to avoid partitioning the disk and only use LVM which takes the LUKS volumes as PVs. | 14:53:42 |
| SigmaSquadron | Redacted or Malformed Event | 14:57:18 |
| SigmaSquadron | I've tried using the following configuration, but it fails since it's missing the partition table type:
{
disko.devices.disk."nvme0" = {
type = "disk";
device = "/dev/disk/by-id/nvme-ID";
content = {
luks = {
size = "100%";
content = {
type = "luks2";
name = "luks-0";
passwordFile = "/tmp/disko/luks/nvme0.key";
askPassword = false;
extraFormatArgs = [
"--cipher=aes-xts-plain64"
"--hash=sha512"
"--key-size=512"
"--iter-time=5000"
"--header=/dev/disk/by-id/usb-ID-part2"
];
extraOpenArgs = [
"--header=/dev/disk/by-id/usb-ID-part2"
];
settings = {
header = "/dev/disk/by-id/usb-ID-part2";
preLVM = true;
allowDiscards = true;
};
initrdUnlock = true;
content = {
type = "lvm_pv";
vg = "NixOS";
};
};
};
};
};
}

is luks2 a valid type? shouldn't it be just luks? | 15:05:09 |
| SigmaSquadron | Right, but even switching to just luks, the same error occurs, since it’s searching for the type in lib/types/table.nix | 15:06:28 |

Right, but even switching to just luks, the same error occurs, since it’s searching for the type in lib/types/table.nix hmmm it looks like disko supports luks as a content type for disk. one sec, let me poke at it | 15:08:04 |

oh you're just missing type entirely. that's what's happening here (the disko test i just made for bare luks worked fine). try this:
{
disko.devices.disk."nvme0" = {
type = "disk";
device = "/dev/disk/by-id/nvme-ID";
content = {
type = "luks";
name = "luks-0";
passwordFile = "/tmp/disko/luks/nvme0.key";
askPassword = false;
extraFormatArgs = [
"--cipher=aes-xts-plain64"
"--hash=sha512"
"--key-size=512"
"--iter-time=5000"
"--header=/dev/disk/by-id/usb-ID-part2"
];
extraOpenArgs = [
"--header=/dev/disk/by-id/usb-ID-part2"
];
settings = {
header = "/dev/disk/by-id/usb-ID-part2";
preLVM = true;
allowDiscards = true;
};
initrdUnlock = true;
content = {
type = "lvm_pv";
vg = "NixOS";
};
};
};
}

| SigmaSquadron | That did indeed work. Thank you! | 15:23:20 |

 Mic92 | raitobezarius: I had to solve a similar issue with disko-install now where disk at install time are different from boot | 05:10:34 |
| Mic92 | Disko-install let's you re-assign disks: https://github.com/nix-community/disko/blob/master/docs/disko-install.md | 05:12:50 |
| Mic92 | Otherwise Disko's image creation Skript will also work. | 05:17:45 |

| tcurdt | so, I have run disko ... now I want to try a nixos-install --flake .
for that it seems like I have to add the disko config.
is that really required? | 21:08:44 |
 bumperboat | The disko module configures the mount points (and lvm, luks, etc) in the nixosConfiguration. Otherwise you'll have to do it twice I'd think | 22:09:14 |
