How to Fix MongoDB Error Code - 13388 - StaleConfig

MongoDB is a popular NoSQL database that offers high performance, scalability, and flexibility. However, like any software, it can encounter errors that need to be resolved. One such error is MongoDB Error Code - 13388, also known as StaleConfig. In this article, we will explore what this error means and how to fix it.

Understanding MongoDB Error Code - 13388 - StaleConfig

When you encounter MongoDB Error Code - 13388, it means that the configuration data on your MongoDB cluster has become stale or outdated. This error typically occurs when there is a mismatch between the configuration data stored on the config servers and the actual state of the cluster.

The StaleConfig error can lead to various issues, such as incorrect shard distribution, unbalanced data distribution, or even data loss. It is crucial to address this error promptly to ensure the stability and reliability of your MongoDB deployment.

Fixing MongoDB Error Code - 13388 - StaleConfig

Here are some steps you can take to fix the StaleConfig error:

Step 1: Identify the Affected Shards

The first step is to identify the shards that are affected by the StaleConfig error. You can do this by connecting to your MongoDB cluster and running the following command:

use config
db.shards.find({ "stale" : true })

This command will return a list of shards that have stale configuration data.

Step 2: Update the Configuration Data

Once you have identified the affected shards, you need to update the configuration data to resolve the StaleConfig error. MongoDB provides a built-in command called "cleanupOrphaned" that can help with this. Run the following command for each affected shard:

use admin
db.runCommand({ cleanupOrphaned: "shardsvr" })

This command will update the configuration data for the specified shard and remove any stale or orphaned data.

Step 3: Verify the Fix

After updating the configuration data, it is essential to verify that the StaleConfig error has been resolved. You can do this by running the following command:

use config
db.shards.find({ "stale" : true })

If the command returns an empty result, it means that the StaleConfig error has been fixed, and the configuration data is up to date.

Conclusion

MongoDB Error Code - 13388, or StaleConfig, can cause issues with the configuration data on your MongoDB cluster. By following the steps outlined in this article, you can resolve this error and ensure the stability and reliability of your MongoDB deployment.
