hi, it's been a few weeks since rhel/centos 5.4 released and there were many discussion about this new "feature" the weekly raid partition check. we've got a lot's of server with raid1 system and i already try to configure them not to send these messages, but i'm not able ie. i already add to the SKIP_DEVS all of my swap partitions (since i read it on linux-kernel list that there can be mismatch_cnt even though i still not understand why?). but even the data partitions (ie. all of my servers all raid1 partitions) produce this error (ie. ther mismatch_cnt is never 0 at the weekend). and this cause all of my raid1 partitions are rebuild during the weekend. and i don't like it:-( so my questions: - is it a real bug in the raid1 system? - is it a real bug in my disk which runs raid (not really believe since it's dozens of servers)? - the /etc/cron.weekly/99-raid-check is wrong in rhel/centos-5.4? or what's the problem? can someone enlighten me? thanks in advance. regards.
