Example2 Adding cluster nodes (multiple data disks)

This example shows you how to add a node with multiple data disks to a cluster.

1. Set DataDisks in InstanceAdvancedSettings to set the mounting information for multiple data disks. The backend will match data disks with data disk IDs based on their types and sizes and mount them to the corresponding paths.
2. Set DataDisks in RunInstancePara. This parameter will be passed through to the CVM to indicate the purchase of multiple data disks.
3. MountTarget in InstanceAdvancedSettings is disused.
