Default Server offline :-( please help to repair software RAID

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?

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.

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)

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.

Michel

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"?


# cat /proc/mdstat
Personalities : [linear] [raid0] [raid1]
md0 : active raid1 sda1[0] sdb1[1]
1023936 blocks [2/2] [UU]

md1 : active raid1 sda3[0] sdb3[1]
20479936 blocks [2/2] [UU]
[=================>...] resync = 86.6% (17746816/20479936)
finish=0.3min speed=131514K/sec

md2 : active raid1 sda5[0] sdb5[1]
277728192 blocks [2/2] [UU]

md3 : active raid1 sda6[0] sdb6[1]
185151360 blocks [2/2] [UU]

unused devices: <none>

..........Then after some wait:.......


# cat /proc/mdstat
