request body

  1. Mandatory properties. These properties must be specified for each logical disk and have no default values.
  • size_gb - Size (Integer) of the logical disk to be created in GiB. MAX may be specified if the logical disk should use all of the remaining space available. This can be used only when backing physical disks are specified (see below).
  • raid_level - RAID level for the logical disk. Ironic supports the following RAID levels: 0, 1, 2, 5, 6, 1+0, 5+0, 6+0.
  1. Optional properties. These properties have default values and they may be overridden in the specification of any logical disk.
  • volume_name - Name of the volume. Should be unique within the Node. If not specified, volume name will be auto-generated.
  • is_root_volume - Set to true if this is the root volume. At most one logical disk can have this set to true; the other logical disks must have this set to false. The root device hint will be saved, if the driver is capable of retrieving it. This is false by default.
  1. Backing physical disk hints. These hints are specified for each logical disk to let Ironic find the desired disks for RAID configuration. This is machine-independent information. This serves the use-case where the operator doesn’t want to provide individual details for each bare metal node.
  • share_physical_disks - Set to true if this logical disk can share physical disks with other logical disks. The default value is false.
  • disk_type - hdd or ssd. If this is not specified, disk type will not be a criterion to find backing physical disks.
  • interface_type - sata or scsi or sas. If this is not specified, interface type will not be a criterion to find backing physical disks.
  • number_of_physical_disks - Integer, number of disks to use for the logical disk. Defaults to minimum number of disks required for the particular RAID level.
  1. Backing physical disks. These are the actual machine-dependent information. This is suitable for environments where the operator wants to automate the selection of physical disks with a 3rd-party tool based on a wider range of attributes (eg. S.M.A.R.T. status, physical location). The values for these properties are hardware dependent.
  • controller - The name of the controller as read by the driver.
  • physical_disks - A list of physical disks to use as read by the driver.

json sample 报文样例

sda和sdb做raid5做系统盘：

{
  "logical_disks": [{
    "size_gb": 100,
    "raid_level": "5",
    "controller": "test",
    "physical_disks": ["sda", "sdb"],
    "is_root_volume": true
   }]
}

sda和sdb做raid0+1，做系统盘，sdc、sdd和sde做raid5：

{
  "logical_disks":
    [
      {
        "size_gb": 50,
        "raid_level": "1+0",
        "controller": "RAID.Integrated.1-1",
        "is_root_volume": true,
        "physical_disks": [
                           "sda",
                           "sdb"
                          ]
      },
      {
        "size_gb": 100,
        "raid_level": "5",

                           "sde"
                          ]
