Tune2fs is now able to switch modes again. What is the preferred mode for a home desktop system with ext4? Is writeback still the fastest, but ordered data has more data integrity? And does delalloc only work when writeback is enabled? And does the commit=XX seconds still only work with writeback mode, ala ext3, or is it a valid option with ordered data mode? Trying to get an idea of the plethora of new options available with ext4. Keep up the good work! Gary
