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?

That's potentially promising. What does 'cat /proc/mdstat' show? Did you have to recover the array, or were you able to use /etc/mdadm.conf?

I'd wait for it to finish and then try rebooting normally. Post back after md1 and md3 are completed sync'ing.

Let md3 rebuild, wait for md1 to rebuild (check regularly with cat /proc/mdstat) and reboot your machine without the rescue, it should come up again.

Run 'watch cat /proc/mdstat'. :)
Thank you all, it seems to have finished - I'm rebooting.
Just curious why is the State of md3 "active", while the others are "clean"?

On the 2nd try it has booted and seems to work.

Did it give an error on the first try and if so, which one ?
You should check /var/log/messages for i/o errors and check your disks with smartctl
I have had my raid1 arrays rebuild sometime without a (for me known) reason. Even had a defective networkcard kernel panic the machine for two hours and the raids were still working afterwards ;)

Turned out, smartd kept saying, that it had no entries in smartd.conf.
I've copied smartd.rpmnew over smartd.conf, restarted it, now I have (in /var/log/messages, date+hostname removed):

Do you think it is configured okay this way?

By the "long tests" do you mean some Linux command I could run while booted in "rescue mode"?
Or do you mean inserting Seagate/WD/whatever CD?
(Because Strato.de people refuse to do the latter - I only pay EUR 29 + 59/month, locked until Dec., why would they do anything for me /sarcasm)

This does not mean necessarily mean that something is wrong. Writes are not occuring at exactly the same time, there is a short timespan where data is written to disk A but not yet to disk B. So it is possible that 2 mirrored blocks hold different data.

$ smartctl -t long /dev/sdX
No need for rescue mode.

Thank you all, it seems to have finished - I'm rebooting.
Just curious why is the State of md3 "active", while the others are "clean"?
If I remember right, clean means it is completely synced and not being written to or mounted. Active means it is or has been written to and is synced. Usually dirty means that there is un-synced data on one or the other drives.
Hi,
what is the output of 'cat /proc/mdstat' ?
A healthy raid should look something like below : [root@janeway ~]# cat /proc/mdstat Personalities : [raid1] md2 : active raid1 sdb1[0] sda1[1] 256896 blocks [2/2] [UU]
md0 : active raid1 sdd1[0] sdc1[1] 1465135936 blocks [2/2] [UU]
md3 : active raid1 sdb3[1] sda3[0] 730218432 blocks [2/2] [UU]
I have 3 RAID1 arrays (over 4 disks)

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/md0in 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?
A 'cat /proc/mdstat' should show the state of the raid mirroring. I don't see anything that would explain not booting, though. Raid1 works normally even when only one member is available and should continue to work while rebuilding. Maybe the problem that caused the mismatch has corrupted the drive the system normally boots.
