PS: You had a /dev/sdd3 partition for RAID0 (/dev/sdd2 was swap).

you need to run fdisk on /dev/sdd
create a Linux raid software partition ( type : fd ) .
after the raid partition is ready simply:
Code:
mdadm /dev/md1 --manage --add /dev/sdd1
and the raid will rebuild.

to see the rebuild status
cat /proc/mdstat

you dont have to reinstall.

whats the output of
cat /proc/mdstat
and
mdadm --misc --detail /dev/md1

Myatu I am getting pretty lost here. lol.

I wonder if you would be willing to have a quick look at the server for me. I would be happy to pay for the service.

Many thanks.

Ah, look at this. I've just gone through all this, and the answer might even be more clearer in your case

How many HD's did your server originally come with? 4 I assume (kimsufi i7-4t)? Look at this from your fdisk -l output:

Code:
Disk /dev/sda: 1000.2 GB, 1000204886016 bytes
...
Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes
...
Disk /dev/sdc: 1000.2 GB, 1000204886016 bytes
...
Where did the 4th "/dev/sdd" go?

Anyway, previous post might still help someone else But in your case, one HD is due for replacement.

Myatu
17-02-2010, 20:43
Instead of "sda1" through "sda3" with smartctl, use "sda", "sdb", etc. (sda1, sda2, etc is the same HD).

To check the current status of the array, use "mdadm -D /dev/md1"; here you *do* increment the digit, ie., /dev/md2, /dev/md3, etc for other arrays. You can check how many you have with "ls /dev/md?" if you aren't sure. Alternatively, a little less descriptive output can be gained from "cat /proc/mdstat", which gives something like this if you have a degraded array:

Code:
Personalities : [raid1] [raid0] [raid6] [raid5] [raid4] [linear] [multipath] [raid10] 
md1 : active raid1 sda1[0]
      20482752 blocks [2/1] [U_]
      
md2 : active raid1 sda2[0] sdb2[1]
      711044864 blocks [2/2] [UU]
      
unused devices: 
Here you can see that "md1" has only 1 out of 2 disks working:

Code:
20482752 blocks [2/1] [U_]
Though this does not seem obvious, given that there are only two HDs in the system, this shows that sda is up ("U") and working, sdb (2nd) is down ("_").

Now, the first thing you need to do is figure out why it failed, and smartctl will tell you. Apparently the error is not on /dev/sda, so check /dev/sdb. If I had to guess, you'd see either (or both) of the following a value other than zero:

Code:
197 Current_Pending_Sector 0x0032 200 200 000 Old_age Always - 0
198 Offline_Uncorrectable 0x0030 200 200 000 Old_age Offline - 0
If that's the case, you first need to do a hard-reset of your server (from the OVH Manager). Reason being is that HD simply do get a few bad sectors with age. If this value is low, then you really shouldn't have to worry. In fact, that's why HD manufacturers set aside a few spare sectors, which will replace the bad ones. And such a replacement can only be done on a cold-restart of the HD (full power down/up).

After this, run smartctl on the "bad" HD again. Current_Pending_Sector should be zero, and Offline_Uncorrectable should have been incremented (by the previous Current_Pending_Sector). If that's NOT the case (that is, Current_Pending_Sector is not zero), do a full test on the HD with "smartcl --test=long /dev/sd". This will literally take hours, even a full day, so best to do this before you head off to sleep -- smartctl will give you an indication of approximately how long this will take. It's safe to exit SSH, since it's done by the HD firmware itself.

If there was an error, you'll find out with a subsequent "smartcl -a /dev/sd" run, for example:

Code:
# 2  Extended offline       Completed: read failure       90%      3008         157                65386
If this is the case, your HD is truly done with and will become part of http://www.youtube.com/watch?v=BJhwhN3GNdY - Send the output details to OVH support, and they should replace it.

On the other hand, if you're getting "Completed without error", you should be OK to rebuild your array. You can do this adding the HD back ON THE CORRECT PARTITION. For example, if "mdadm -D /dev/md1" shows /dev/sda1, then you use "mdadm --add /dev/md1 /dev/sdb1" (note the "/dev/sdb1"!). And so on for all the other arrays. Word of advice though: Backup, backup, backup! (Okay, so 3 words )

this one looks fine.

You must have another hard drive there to do the RAID with. Would you check the other one too?

When I do the above test this is the result.

yeah, check the state of the RAID and it's been rebuild. Look out for error logs regarding the drive that's been degraded, and if they show that there is a hardware fault, open a ticket with it (or send them to us, in the support, and we'll open a ticket for you), the engineers will change it for you, but it's important that you show them hardware fault

You can run:
# smartctl -a -d ata /dev/sda
in rescue mode for quick check

As this is Raid 1, you might just have a fault with one of the disks.
Log into the server and check the status of MD1.
It should tell you which disk has a problem.

My server went out at this morning and has been placed in rescue mode.

I have gone in via the web interface and the only things I can see is under the raid.

State of MD1 (Raid 1) degraded

I have run all tests and that is the only thing I can see.

Any ideas on what I should do, Can I repair this fault without having to do a complete reinstall. I do have offline back ups but wonder if it is possible to access the other disks as I am using all of the disks as one.

Server running CentOS 5.2

Many thanks.
