RE[6]: Ext4 as default

Member since:

If ext4's current default config is truly robust, that's great. I'm very excited about ext4. But I would be interested in how you would relate your observations to the quote, below, from Ted's blog. If you could satisfactorily resolve that discrepancy, then I would probably be satisfied. Even happy. :-)

Another solution is a set of patches to ext4 that has been queued for 2.6.30 merge window. These three patches (with git id’s bf1b69c0, f32b730a, and 8411e347) will cause a file to have any delayed allocation blocks to be allocated immediately when a file is replaced. This gets done for files which were truncated using ftruncate() or opened via O_TRUNC when the file is closed, and when a file is renamed on top of an existing file. This solves the most annoying set of problems where an existing file gets rewritten, and thanks to the delayed allocation semantics, that existing file gets replaced with a zero-length file. However, it will not solve the problem for newly created files, of course, which would have delayed allocation semantics.

The bolding, above, is mine, of course.
