When the Oracle ACFS file systems are created, they do not initially consume all of
the storage in the appliance. Space is preserved for additional repositories, or in some
cases, database files stored directly in Oracle ASM. You can check for available
storage space in your file systems by running the operating system command df -k
as shown in the following example.
# df -k
