[RDS] Mandatory OS update but no maintenance in console?

Question

Hello,

I received an email from AWS saying I have an mandatory OS update for my RDS (MariaDB) in N.Virginia.

I have checked the Maintenance & backups section in the RDS console but found no OS update. There is only "Auto minor version upgrade".

I also have checked AWS Health Dashboard but found nothing on the "Open and recent issues", "Schedulled changes", "Other notification", and "Event log". They are all zero.

I also have checked the result of the command "aws rds describe-pending-maintenance-actions" and the result was:
{
    "PendingMaintenenaceActions": []
}

I also have read the post ( https://repost.aws/questions/QUM7E7C5aaSsWZejFs2ev3zQ/rds-os-update-is-available-don-t-see-it-in-rds-dashboard ) but I'm still not sure what was going on.

Is the content of the email wrong or should I check it somewhere else?

What should I do?

Accepted Answer

Hello,

The operating system update is required for your DB instance based on it's DB engine version and DB instance class of your DB instance automatically.

If an OS update is required for your DB instance based on it's DB engine version and DB instance class, the required update appears in the AWS Management Console. For further clarification on this, please visit [Recommended actions for mandatory operating system updates](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_UpgradeDBInstance.Maintenance.html#Aurora.Maintenance.Mandatory_OS_Updates.Recommended_Actions)

Please refer to this [AWS Document ](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_UpgradeDBInstance.Maintenance.html#Aurora.Maintenance.Mandatory_OS_Updates.MySQL) to see instance types and engine versions that are eligible.

Follow the instructions in [Applying updates for a DB instance](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_UpgradeDBInstance.Maintenance.html#USER_UpgradeDBInstance.OSUpgrades).

Updates specific to MariaDB, can be found [here](https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_UpgradeDBInstance.MariaDB.html)
