And this, again, fits in the discussion of RAID-6 error check and, potentially, repair. Ideally the log should tell which (RAID) address has a mismatch and, in case of RAID-6, if a specific device could be faulty at that position. This would be already quite a huge step forward in improving the overall reliability of the RAID sub-system. Side note: in F11 there is this cron.weekly raid-check, but nothing is reported (per email to root) in case of mismatch. Is there any plan to add a such a facility?
