My discussions with some of the Gentoo developers there seems to be a number of them that have/had experienced data loss in the past and I think some of them have a problem that it only journals metadata.
The pre 1.1 releases had this problem. It should be a lot less common since the 1.1 release.
So far I have had good success and the problems I did encounter could be worked around or fixed.
Looks like XFS didn't make it in to the latest 2.4.19 kernel they have in testing right:
XFS will only be integrated in 2.4 after it has succesfully made it in 2.5 according to Marcello.
The merge would happen in 2.5.36 and we currently have 2.5.35 so a bit of patience please.
Also of note is that the 2.4 tree is different from the 2.5 tree in many respects. You can find a link to Christoph' checklist in the FAQ that shows what functionality is available in 2.4 and 2.5 and what needs to be done to make it fit in.
I think some of the developers feel they can't recommending XFS due to past experiences and I think they have the impression that XFS won't or is hard to patch into their mainline kernel now due to other features they want to offer.
I think that other than the metadata, their fears are unfounded but I don't know how to open a discussion with them them about how some of the problems that they experienced with early XFS up to and including 1.1 (where the 2.4.19-r7 XFS patches come from) does not reflect on the sheer amount of testing and bug fixing have occured in CVS (even if you just consider the 2.4.19 XFS kernel sync)
Perhaps I could patch a current XFS into their current (2.4.19-r9) and running the test suite? Is there anything else that might be suggested.
There are some new features in current CVS that need somoe more testing. I believe a patch with more recent XFS code is going to Andrea and you might be able to use that as well. No warranty though since it is not a full fledged release (== tested).
I suppose a good starting point would be to see which of their patches overlap with the XFS 2.4.19 or CVS code.
