Thanks for link. I've tried kernel linux-3.1-rc9, xfs behaves better but
still is something not right. I'm rsyncincg many files, after sometime
rsync hangs, it looks like do nothing for about 30-90 seconds and
continues copying. I did run "sync" when rsync was hanging and sync also
hangs. It looks like xfs has hiccup.
Regards,
Marcin
