Hi again, forgot one thing... I've some PCs where those mismatches shows up, sometimes more, sometime less, sometimes nothing. All these PCs have the filesystem (ext3) directly on the RAID drive. I've one more PC, where there is a LVM layer inbetween. In this PC, which has also different HW (the others are all identical), I never saw mismatches. I can imagine the LVM takes care of handling properly the memory buffers. Can anyone confirm this?
