Ts'o: Delayed allocation and the zero-length file problemTs'o: Delayed allocation and the zero-length file problemPosted Mar 16, 2009 22:51 UTC (Mon) by masoncl (subscriber, #47138)In reply to: Ts'o: Delayed allocation and the zero-length file problem by njs Parent article: Ts'o: Delayed allocation and the zero-length file problem
That's correct. The main point behind data=ordered is to make sure that if you crash you don't have extent pointers in the file pointing to extents that haven't been written since they were allocated.
Without data=ordered, after a crash the file could have garbage in it, or bits of old files that had been deleted.
