Check Details
- Check requirements: if the source database is a sharded instance, you need to disable the balancer in it before you can start migration.
- Check description: an incremental migration task will get the oplog. If the balancer is enabled,
moveChunkin the source database may cause data inconsistency in the target database.
Fix
- Log in to the source database.
- Run the following command to disable the source database balancer:
sh.stopBalancer() sh.getBalancerState() - Run the verification task again.
Yes
No
