Check Details
Check requirement: For MongoDB synchronization tasks where the source is a shard, it is required to enter the corresponding mongos, config server, and mongod node information.
Check description: Incorrect entry of the mongos, config server, and mongod node information can cause data migration errors. For example, enter the mongos node information into the mongod field. Note that only one mongod node needs to be specified per shard.
Fixing Method
Ensure the correct node information is entered in each input field of the Data Transfer Service (DTS) task.
Specify only one mongod node per shard.
