NixOS is a Linux distribution where everything is described as code, with one exception: during installation, the disk partitioning and formatting are manual steps. **disko** aims to correct this sad 🤡 omission.
|
||
|
||
This is especially useful for unattended installations, re-installation after a system crash or for setting up more than one identical server.
|
||
|
||
## Overview
|
||
|
||
**disko** can either be used after booting from a Nixos installer, or in conjunction with [nixos-anywhere](https://github.com/numtide/nixos-anywhere) if you're installing remotely.
|
||
|
||
Before using **disko**, the specifications of the disks, partitions, type of formatting and the mount points must be defined in a Nix configuration. You can find [examples](./example) of typical configurations in the Nix community repository, and use one of these as the basis of your own configuration.
|
||
|
||
You can keep your configuration and re-use it for other installations, or for a system rebuild.
|
||
|
||
**disko** is flexible, in that it supports most of the common formatting and partitioning options, including:
|
||
|
||
- Disk layouts: GPT, MBR, and mixed.
|
||
- Partition tools: LVM, mdadm, LUKS, and more.
|
||
- Filesystems: ext4, btrfs, ZFS, bcachefs, tmpfs, and others.
|
||
|
||
It can work with these in various configurations and orders, and supports recursive layouts.
|
||
|
||
## How to use disko
|
||
|
||
Disko doesn't require installation: it can be run directly from nix-community repository. The [Quickstart Guide](./docs/quickstart.md) documents how to run Disko in its simplest form when installing NixOS.
|
||
|
||
For information on other use cases, including upgrading from an older version of **disko**, using **disko** without NixOS and downloading the module, see the [How To Guide](./docs/quickstart.md)
|
||
|
||
For more detailed options, such as command line switches, see the [Reference Guide](./docs/reference.md)
|
||
|
||
To access sample configurations for commonly-used disk layouts, refer to the [examples](./examples) provided.
|
||
|
||
## Sample Configuration and CLI command
|
||
|
||
A simple disko configuration may look like this:
|
||
|
||
```
|
||
{ disks ? [ "/dev/vdb" ], ... }: {
|
||
disk = {
|
||
vdb = {
|
||
device = builtins.elemAt disks 0;
|
||
type = "disk";
|
||
content = {
|
||
type = "table";
|
||
format = "gpt";
|
||
partitions = [
|
||
{
|
||
type = "partition";
|
||
name = "ESP";
|
||
start = "1MiB";
|
||
end = "100MiB";
|
||
bootable = true;
|
||
content = {
|
||
type = "filesystem";
|
||
format = "vfat";
|
||
mountpoint = "/boot";
|
||
};
|
||
}
|
||
{
|
||
name = "root";
|
||
type = "partition";
|
||
start = "100MiB";
|
||
end = "100%";
|
||
part-type = "primary";
|
||
bootable = true;
|
||
content = {
|
||
type = "filesystem";
|
||
format = "ext4";
|
||
mountpoint = "/";
|
||
};
|
||
}
|
||
];
|
||
};
|
||
};
|
||
};
|
||
}
|
||
```
|
||
|
||
If you'd saved this configuration in /tmp/disko-config.nix, and wanted to create a disk named /dev/nvme0n1, you would run the following command to partition, format and mount the disk.
|
||
|
||
```
|
||
$ sudo nix run github:nix-community/disko -- --mode disko /tmp/disko-config.nix --arg disks '[ "/dev/nvme0n1" ]'
|
||
```
