This is probably a naive question, but this thread has already proved me wrong on one naive assumption..... If the sequence is: 1. append some data to file A 2. fsync(A) 3. append some further data to A 4. some writes to other files 5. power loss Is it guaranteed that all the data written in step 1 will still be intact? The potential problem I can see is that some data from step 1 may have been written in a tail, the tail moves during step 3, and then the original tail is overwritten before the new tail (including data from before the fsync) is safely on disk.
