[CentOS] Server offline :-( please help to repair software RAID

Thu Apr 28 19:07:26 UTC 2011
Alexander Farber <alexander.farber at gmail.com>

Hello,

since weeks I was ignoring this warning at my CentOS 5.6/64 bit machine -

    /etc/cron.weekly/99-raid-check:
    WARNING: mismatch_cnt is not 0 on /dev/md0

in the hope that the software RAID will slowly repair itself.

I also had executed "echo 100000 > /proc/sys/dev/raid/speed_limit_max"
on the advice from the mailing list.

But now my web server is offline - I had to boot it remotely with rescue system.

Does anybody please have an advice what commands to run
and do you think it is a RAID problem at all?
