Hi!

Well, what could be the reason? I mean, there was no hardware failure,
no crash, no reboot, no errors in the disk's SMART error log, no nothing.
What I did was that I've extracted and deleted the rather huge OpenOffice
source tree several times (sometimes with overwriting) and finally it
ended up with these undeletable files and xfs errors. Is it considered
normal for xfs to get messed up like that under such load?

Thanks,
Sab
