What to do if you run out of disk space
When the initial chunk of the dbspace that you are creating is a cooked file on UNIX or an NTFS file on Windows, the database server verifies that the disk space is sufficient for the initial chunk.
If the size of the chunk is greater than the available space on the disk, a message is displayed and no dbspace is created. However, the cooked file that the database server created for the initial chunk is not removed. Its size represents the space left on your file system before you created the dbspace. Remove this file to reclaim the space.
