  Table 3 Data structure description of the volume field

  Name	Type	Mandatory	Description
  group_id	String	No	The role ID. For a cluster instance, this parameter is set to the ID of the shard group. This parameter is not transferred for replica set instances.
  size	String	Yes	The requested disk capacity. The value must be an integer multiple of 10 and greater than the current storage space. In a cluster instance, this parameter indicates the storage space of shard nodes. The value range is from 10 GB to 2000 GB. In a replica set instance, this parameter indicates the disk capacity of the DB instance to be expanded. The value range is from 10 GB to 3000 GB. In a single node instance, this parameter indicates the disk capacity of the DB instance to be expanded. The value range is from 10 GB to 1000 GB.
  node_ids	Array of strings	No	This parameter is required when the disk capacity of the read replica of a replica set instance is expanded. Only one element can be transferred in the list.
