Mmm... (Not related to above) read this, it will give you an idea of the problem, that not even data journalling solves, AFAIK:
Delayed allocation and the zero-length file problem http://thunk.org/tytso/blog/2009/03/12/delayed-allocation-and-the-zero-lengt...
Dont fear the fsync! http://thunk.org/tytso/blog/2009/03/15/dont-fear-the-fsync/
Neither of which helps someone running an application unless they are willing to modify the code to assure there are fsync calls after every write/close.
(I doubt you have read all the comments yet... you haven't had the time!)
And neither are particularly enlightening as to the problem at hand, namely, selecting the FS that is least vulnerable by design.
Yes, it does: the point is that you have to use an UPS, because software is not good enough, and is not in our hands as users. No filesystem choice can be safe enough. And fsck-ing a 2 TB ext3 partition is daunting!
Further, with regard tot he second article linked above, hand waiving away performance hits by referencing some obscure firefox bug doesn't say a thing about real world performance problems which would occur if EVERY app were re-written to use fsync calls always and everywhere.
No, the problem is not a FF bug, but that it brought some attention to the problem in the filesystem design. Notice that, IMO, the most interesting insights are not in the article, but in the comments. - -- Cheers, Carlos E.
