How-to create a new raid group in an existing aggregate
Limitation:
- Each aggregate uses the same raid type. For example, when an aggregate was created with Raid-DP, any other raid groups created in the future will all belong Raid-DP. Even changing raid type in the aggregate, all the raid groups will be also changed at the same time.
- The name of raid groups can not be changed. It will be automatically assigned as rg0, rg1, rg2, and so on.
