# mongocli cloud-manager clusters resync

Start an initial sync for a cluster or process.

The MongoDB Agent checks whether the specified timestamp is later than the time of the last resync, and if confirmed, the MongoDB Agent:

1. Starts the initial sync on the secondary nodes in a rolling fashion

2. Waits until you ask the primary node to become the secondary with the rs.stepDown() method

3. Starts the initial sync on the primary node

Warning: Use this method with caution. During initial sync, Automation removes the entire contents of the node’s dbPath directory.
