Hi Team,
Use mongorestore to restore the backup data of replica set cluster A to replica set cluster B.the user configuration information of the two clusters is the same.
When using mongorestore for the first time to restore in cluster B, after the user/role information is restored, subsequent operations will prompt that there is no permission, but there is no current problem when mongorestore is executed repeatedly.
