Check Details
Check requirements: in a MongoDB migration task, if the source database is a sharded database, you need to enter the mongos
, config server
, and mongod
node information.
Check description: the information of the mongos
, config server
, and mongod
nodes cannot be disordered; otherwise, data migration will also be disordered; for example, the mongos
node information should not be entered in the box for the mongod
node. Note that you only need to enter the information of one mongod
node for each shard.
Fix
Enter the correct node information in the DTS task configuration items.
Enter only one mongod
for each shard.
