P35-DS3R RAID1 Conflict

[Wcviper]

I have been running this system fine for a few years now. Booted today and got message that there was no system drive. When I check the RAID setup by selecting CTRL-G at boot, the system shows the two hard drives in the top right, but in the RAID drive list, the kiting shows:

RDD0:  GRAID     1- Mirror     160GB   Conflict   01

In the above it is Status=Conflict and Members=01

The menu options that I think I need to use to attempt a repair is "Solve Mirror Conflict". The problem is that I don't know which drive to select as the source when stepping through the options. There are only two drives in the system and one RAID 1 drive in the list. I can select the RAID drive with only one selection, but the next step asks for the "source" drive. If I select the wrong one, I could lose everything.

I can't boot to windows to check anything as this is my system drive.

Does the members=01 mean anything? Is that the good drive or bad drive?

I have spent hours search the web with no success. Lots of info on setting it up, nothing on fixing problems!!!

Anyone have any ideas?

Hi

I understand your dilemma there but can't think of a way to get passed it. Obvoiusly it is telling you that one of the mirror drives has failed but as you say which one?  My only idea would be to disconnect one of the drives and then restart, enter the RAID page and see if the information that it then shows can help you.

The only person who might know for certain is Pierre but I haven't seen him around on the forum for a while. I will try and contact him and see if he can be persuaded to take a look at your post.

*
OS run in RAID 1 ( mirror ) with only one disk

test with the first , if system run fine save your disk content and reinstall OS

If you cannot with the first ,  test with only the second disk

If you have always a problem install OS in a third disk and use testdisk or similar program for restore RAID disk content

Thanks for coming in and helping out on this one Pierre. Now that you've said it the solution seems so straightforward.

Thanks for your input. I disconnected each drive and tried to reboot. Each drive worked as a standalone boot drive so I went back to both drives connected and took a chance resolving the conflict then rebuilding the mirror. It worked and the system is back in operation with no lost data.

I just wish I knew why it happened in the first place so that I can keep a disaster from occurring such as a dead drive.

Appreciate the help!!!

Thank you for this, Pierre. I had the same problem, but with a 2000GB RAID-1 Mirror. Can't say how glad I am to learn that it was so easily resolved.

But now I'm absolutely certain I'm never going to use the buildt in raid on my GA-965P-DS3 rev. 3.3 anymore.. Seems like it's safer to just manually copy everything to an external drive instead.
