Attempting to Recover Failed RAID 10
Posted: Mon Mar 11, 2013 10:41 am
I have a huge problem. I do not know a whole lot about RAID, but we have a 4 disk RAID 10 setup before I ever arrived here. It is on an INTEL board, which I think it software RAID so of course problems there.
My raid 10 has 1 Volume, 2 Spans, with 2 disks each in them.
Today, disk 4 of RAID stated failed, so SPAN 1 was degraded. I repalaced the drive and rebooted then suddenly Disk 5, the second of the two drives in SPAN 1 stated failed, now the volume is inaccessible. I am not sure what has happened, but I desperately need this data back. It was suggested that I attempt to use R-Studio and was told it worked well.
I installed the demo for now to see what I could see and when I open the console, I do not see the drive listed that are in the RAID 10 - the 2 good ones (Span 0) or the two failed ones (Span 1).
If I understand correctly, I would essentially use R-Studio to build a virtual RAID from these drives, copy the data to another location and then rebuild the raid, copy data back over. Is that correct? If so, how do I go about this? And why can't I see the drives? both are spinning and I find it highly unlikely the data is fully lost because just before I swapped out the initial failed drive, all the data was accessable. I was told this is probably more of a controller issue than anything. Thanks.
