Dataserver reaches working state but data is not synchronized

[Synex-wh]

Describe the bug

• Expanding new data nodes to achieve working state but the data is not fully synchronized, resulting in new node data holdings not meeting expectations

Analytical solution

• The data synchronization of the new expansion node depends on the notification of other nodes. After receiving the notification, it starts to pull the corresponding version data, and knows that the data is synchronized before the status update of the data node is obtained. The code is as follows:

• The actual situation has received the data pull notification, and there is no older version of the situation, but the data is really missing, only the pull data request is not initiated, the specific code modification point is as follows
