Verifying the flow control configuration

When RDMA is enabled for the cluster, refer to Verifying the flow control configuration for RDMA to verify the flow control configuration on the new nodes.

Note:

Since verifying the flow control configuration requires at least three nodes, you need to determine which nodes should participate in the verification based on the number of nodes added during this expansion.

• If three or more nodes are added, only the new nodes need to be verified.
• If fewer than three nodes are added, you need to add existing nodes from the cluster to the new nodes, forming a group of three nodes for the verification. To avoid any impact on the performance of existing nodes in the cluster, and ensure accurate verification results, it is recommended to perform the verification during business idle time.
