Hello there,

Its 5am and I am having trouble with something called a degraded mirror on my raid array. :thumbsup:

On boot-up the screen which denotes the status of the array (and where you can configure it by pressing F10 I think) it flashes in red type that the arrays are degraded. This is confirmed in the NVRAID manager.

I am at a complete loss. I do not even know where to start. I have tried deleting an array and then hot plugging it back in, I have messed around with the configuration to see whether there would be at least some impact and and I have changed the connections on the SATA ports from SATA1 and 2 to 3 and 4. Is it likely that something on the motherboard has gone pop?

Any help or even just messages of sympathy and condolence would be appreciated otherwise I am going to have to buy another book in which I am not sure I am going to find the answer in anyway.

Many thanks in anticipation

if im correct, there is something wrong with the RAID? Did you get to see the motherboards manufacturer name? You should check it out and see if there is anything with troubleshooting with those mirrors. Also, what kind of computer do you have.

Hi

Thanks for the reply.

The motherboard is an MSI K8N Neo4 with an NVIDIA nForce 4 chipset. I have built my own computer so it is not from a particular manufacturer.

I have actually resolved it at long last. :thumbsup: In NVRAID Manager a right click on the mirroring icon allows you (me!) to rebuild the array which is now denoted as healthy as does the RAID setup screen on boot-up.

However, I wish to avoid this happening again. Is it something generic with RAID, what actually happens for the RAID to degrade and are there any actions I can take to make it more robust or is it something I am just going to have live with?

Thanks again
