If nodes do not meet service requirements, add new nodes to improve storage and usage efficiency.
On the displayed Modify Cluster page, set New Node Quantity as required. You must add at least one node and can add a maximum of 32 nodes. The Node Specifications and Node Storage settings of newly added nodes are the same as those specified during cluster creation. If Disk Encryption is selected during cluster creation, then the same Disk Encryption setting applies to newly added nodes and the key adopted during cluster creation applies.
