Auto grow storage in Azure Database for MariaDB using the Azure portal

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

When a server reaches the allocated storage limit, the server is marked as read-only. However, if you enable storage auto grow, the server storage increases to accommodate the growing data. 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.
