Task center-ApsaraDB for MongoDB(MongoDB)-阿里云帮助中心

Procedure

Go to the Task Center page and select a region at the top.
View task information.

On the Task list page in Task Center, filter tasks by start time (last hour, 1 day, 7 days, 30 days, or a custom range) and by keywords such as a task ID. The top of the page summarizes tasks by status: Succeeded, Failed, Pending Intervention, Pending, Running, Terminating, Terminated, and Pending Schedule. The table lists each task's Task ID, Task type, Resource type, Resource ID, Task status, Task progress, Task time, and Actions. In the Actions column, you can click Details, Modify switchover time, or Retry.

Specification change or migration	ModifyInsSpec	sharded cluster	Modifies the specification of a mongos, Configserver, or shard node; changes the node's instance type; migrates the node to another availability zone; or deletes a read-only node from a shard.
Network change	ModifyNetwork	replica set	Updates the network configuration, which can include routing information or the virtual IP address (VIP).
Network change	ModifyNetwork	sharded cluster	Modifies network settings, such as those for VPC, public network, or classic network.
Lock instance	LockIns	replica set sharded cluster	Locks an instance.
Lock instance	LockIns	replica set sharded cluster	Locks an instance.
Unlock instance	UnlockIns	replica set sharded cluster	Unlocks an instance.
Unlock instance	UnlockIns	replica set sharded cluster	Unlocks an instance.
Add node	AddInsNode	replica set	Adds a node to a replica set instance.
Add node	AddInsNode	sharded cluster	Adds a read-only node to a shard of a sharded cluster instance.
Delete node	DeleteInsNode	replica set	Deletes a node from a replica set instance.
Add shard	AddInsShards	sharded cluster	Adds one or more shards to a sharded cluster instance.
Delete shard	DeleteInsShards	sharded cluster	Deletes a shard from a sharded cluster instance.
Clone instance	CloneIns	replica set sharded cluster	Restores an instance from a backup set, performs a point-in-time recovery (PITR), or recreates an instance from the recycle bin.

Switchover time

For maintenance tasks that involve a switchover—such as upgrades, specification changes, or restarts—you can choose when to perform the switchover:

Execute Now: The switchover runs as soon as preparations are complete.
Execute Within Maintenance Window (Recommended): The system performs the preparations first, and the switchover occurs during your configured maintenance window.

If you need to perform the switchover at a specific time outside the maintenance window, wait until the task status changes to Pending Schedule. Then, at your desired switchover time, click Change Switchover Time in the Actions column of the task list and change the option to Switch Immediately.

FAQ

Why is the "Modify switchover time" option unavailable?

The task does not affect the instance, so modifying the switchover time is not necessary.
The system is still preparing for the switchover, such as creating a new instance or migrating data. This process can take from several minutes to a few hours, depending on the data volume. After the preparations are complete, the task status changes to Pending Schedule, and the option becomes available.

Why is the task still in progress when my service and monitoring appear normal?

After the switchover, your instance is accessible. However, the system continues to perform background cleanup, such as removing the old instance. The task is marked "Succeeded" only after these operations are complete.
