APPLIES TO: Azure Database for MySQL - Single Server

Important

Azure Database for MySQL - Single Server is on the retirement path. We strongly recommend for you to upgrade to Azure Database for MySQL - Flexible Server.

This article describes how you can configure an Azure Database for MySQL server storage to grow without impacting the workload.

The server reaching the storage limit, is set to read-only. If storage auto grow is enabled then for servers with less than 100 GB provisioned storage, the provisioned storage size is increased by 5 GB as soon as the free storage is below the greater of 1 GB or 10% of the provisioned storage. For servers with more than 100 GB of provisioned storage, the provisioned storage size is increased by 5% when the free storage space is below 10GB of the provisioned storage size. Maximum storage limits as specified here apply.
