I created lame test case to catch the bug. Numbers: Filesystem, Method, Performance, Percentage of data loss ext3, (1), 0,50, 1% (one file is partial) ext3, (2), 0,44, 0% (one temporary file is partial) ext3, (3), 0,37, 0% (one temporary file is partial) ext4, (1), 0,50, 102% (all files are zeroed, including my scripts) ext4, (2), 0,44, 101% (all files are zeroed, including one .tmp file) ext4, (3), 0,29, 0% (ext4 is, actually, slower than ext3).
BTW: I see no way to call fsync() in bash, so I used "sync" command instead in method (3). > Finally, I'll note that Fedora folks haven't really been complaining about this, so far as I know. I am Fedora user.
