XFS surely rocks, but it's missing one critical component: data=ordered
And that's one component that's just too critical to overlook for an
enterprise environment that is built on data-integrity over performance.

So that's the secret why people still use ext3, and XFS' reliance on
external hardware to ensure integrity is really misplaced.

Now, maybe when we get the data=ordered onto the VFS level, then maybe
XFS may become viable for the enterprise, and ext3 may cease to be KING.

Wow, thanks for bringing an advocacy thread onto linux-fsdevel.  Just what
we wanted.  Do you have any insight into how to "get the data=ordered
onto the VFS level"?  Because to me, that sounds like pure nonsense.

Well, conceptually it sounds like a piece of cake, technically your guess is 
as good as mine.  IIRC, akpm once mentioned something like this.

But seriously, can you think of a technical reason why it shouldn't be 
possible to abstract data=ordered mode out into the VFS?


Thanks!
