Use Cloud Manager Automation to start an initial sync process on one or more MongoDB instances. This resynchronizes data stored on MongoDB nodes in clusters.
Considerations
You can only resync secondary nodes.
A node might become the primary between the time when you trigger a resync and when it runs. In this case, the MongoDB Agent waits for you to connect to the node manually and run the
rs.stepDown()command.You can only schedule one node in any given replica set to resync at a given time. While one node resyncs, the Cloud Manager disables the Resync option for all other nodes.
Trigger Initial Sync
In MongoDB Cloud Manager, go to the Processes page for your project.
If it's not already displayed, select the organization that contains your desired project from the Organizations menu in the navigation bar.
If it's not already displayed, select your desired project from the Projects menu in the navigation bar.
