Unfortunately, my machines have been run through through the ringer, going for
prolonged periods of time of having problems, including unclean shutdowns (too
many things on plate to address issues that only happened at shutdown, with
often measured in months.
The only non-user-error dataloss I've ever experienced has been attributable
to 2 areas, neither was XFS.
1st was software raid under 11.1: 2/4 volumes unreadable after an unclean
(fortunately it was a backup volume).
and 2nd area was during use of the LSM volume manager -- most recently under
when I upgraded the kernel and volume snaps broke.
I did have a data corruption issue involving XFS with some volume snaps that
under 11.2, but they haven't been reproducible on non-LFM volumes nor on volumes
where volume snaps had not become full (and self-corrupt).
I've been using xfs since the early 2.4 timeframe and was lucky enough to have
system then, on a UPS, so that may have prevented some of the issues you are
referring to, but UPS, hasn't saved my system stability since upgrading to
SuSE 11.0, when stability took a downturn.
However, in that time frame, even with instability, XFS hasn't caused any
noticeable problems, but honestly, in the 8 years of use, if it had, I also keep
daily backups of all data + metadata using xfsdump/restore, and have only had
to resort to them for the problems mentioned above and cockpit error.

Forward this from the linux-xfs list, in hoping that decision-makers willLinda,
consider XFS as the default suse OS install choice.
In the past (2.4.x kernel) XFS had significant data loss issues in the
presence of unexpected shutdowns.
Since desktops/laptops tend to have these much more than servers, I
would not have wanted it to be the default at all during those times.
Has its' resiliency greatly increased? If not, I don't think it is a
good choice for the openSUSE default fs.
