Space Management

The Oracle ACFS file systems are automatically created when you create a shared repository, or when you create a database on Oracle Database Appliance.

However, the file systems do not initially consume all of the storage in the appliance which preserves space for additional repositories, or in some cases, database files stored directly in Oracle ASM. In Oracle Database Appliance software releases 12.1.2.2 and earlier, the Oracle ACFS file systems do not automatically extend if they run low on space, even if storage space is still available in the shared storage pool. You can check for available storage space in your file systems by running the operating system command df -h as shown in the following example.

df -h

To extend the size of one of your file systems to accommodate growth in your data, you must manually expand the pool.
