POST /storage/aggregates

Automatically creates aggregates based on an optimal layout recommended by the system. Alternatively, properties can be provided to create an aggregate according to the requested specification. This request starts a job and returns a link to that job.

Required properties

Properties are not required for this API. The following properties are only required if you want to specify properties for aggregate creation:

  • name - Name of the aggregate.

  • node.name or node.uuid - Node on which the aggregate will be created.

  • block_storage.primary.disk_count - Number of disks to be used to create the aggregate.

Default values

If not specified in POST, the following default values are assigned. The remaining unspecified properties will receive system dependent default values.

  • block_storage.mirror.enabled - false

  • snaplock_type - non_snaplock

  • storage aggregate auto-provision

  • storage aggregate create

Example:

POST /api/storage/aggregates {"node": {"name": "node1"}, "name": "test", "block_storage": {"primary": {"disk_count": "10"}}}
