I want to resolve the “Storage size approaching maximum storage threshold. Increase the maximum storage threshold” message for my Amazon Relational Database Service (Amazon RDS) for MySQL database instance.

Resolution

When storage auto scaling for an Amazon RDS DB instance is turned on, you might receive the following message:

"Storage size amount GB is approaching the maximum storage threshold amount GB. Increase the maximum storage threshold"

To resolve this message, increase the maximum storage threshold by at least 26 percent of the currently allocated storage of the instance. For example, an Amazon RDS instance allocates a storage size of 1999 GiB and the maximum storage threshold is 2300 GiB. For a 26 percent increase, you must increase the maximum storage threshold to 2518 GiB.

Note: If the allocated storage is too close to the maximum storage threshold, then a storage auto scaling operation might not be successful.

If the instance reaches a storage-full state before the maximum storage threshold is set higher, then you must manually increase the storage. To address the storage-full state, see How do I resolve problems that occur when Amazon RDS DB instances run out of storage?
