Why does my database instance suddenly change to read-only and cannot be operated?

To ensure the normal operation of your business, when the space is nearly used up, please upgrade your database instance specifications or purchase hard disk space in time. If you can only select and drop your database, but can’t manipulate (insert, update or delete) data, it means your instance is locked. This can be triggered when your instance size exceeds the maximum allowable storage size of the instance specification.When your instance is locked, you only have permissions to select, show view and drop table.Under such circumstances, it is recommended you upgrade instance specification as soon as possible or purchase extra space independently. You can also drop some useless tables to release more space. The system will automatically unlock your instance once free storage space is sufficient.
