Azure SQL Managed Instance can reach the storage limit if the total sum of sizes of the database (both user and system) reaches the instance limit. In this case the following issues might happen:
- Any operation that updates data or rebuild structures might fail because it cannot be written in the log.
- Some read-only queries might fail if they require tempdb that cannot grow.
- Automated backup might not be taken because database must perform checkpoint to flush the dirty pages to data files, and this action fails because there is no space.
How to resolve this problem is the managed instance reaches the storage limit?
