Disks

The first thing a partitioning table needs is to declare one or more disks that will be used to partition. Each disk declared in the partitioning table has the name sd followed by a letter, starting at a, namely: 1st disk sda, 2nd disk sdb and so on. A disk is one of two types, either MSDOS or LVM, and provides a total disk size available. LVM disks cannot have any physical partitions, however can be used in logical volumes (refer to adv-partitioning-logical-grp-vol).

The example below describes 1 disk of 20GB when using YAML.

installation:
  partitioning:
    disks:
    - name: sda
      type: msdos
      size: 20480

If you are using JSON:

{
  "installation": {
    "partitioning": {
      "disks": [
        {
          "name": "sda",
          "type": "msdos",
          "size": 20480
        }
      ]
    }
  }
}

Example

The following example describes 2 disks of 20GB each when using YAML.

---
installation:
  partitioning:
    disks:
    - name: sda
      type: msdos
      size: 20480
    - name: sdb
      type: msdos
      size: 20480

If you are using JSON:

{
  "installation": {
    "partitioning": {
      "disks": [
        {
          "name": "sda",
          "type": "msdos",
          "size": 20480
        },
        {
          "name": "sdb",
          "type": "msdos",
          "size": 20480
        }
      ]
    }
  }
}
