• A、The deleted file is still open by the application.The system must be rebooted before'df' will show the reduction in the filesystem.
• B、The deleted file is still open by the application.The application must be stoppedbefore 'df' will show the reduction in the filesystem.
• C、The filesystem is still marked as full in the /etc/fs.status file.The system must be rebooted before 'df' will show the reduction in the filesystem.
• D、The filesystem is still marked as full in the /etc/fs.status file.The application must be stopped before 'df' will show the reduction in the filesystem.
