problem killing raid 5

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

I had a raid 5 array on three disks. Because of a hardware problem two disks dissapeared one after the other. I have since been trying to create a new array with them.

Between the degradation of the two disks I tryied removing one of the failed disks and re-adding it to the array. When the second disk failed I noticed the drive numbers on the broken array, and misteriously a fourth drive appeared on it. Now I have numbers 0,1 and 3, but no number 2.
mdadm tells me that number 3 is a spare.

Now I want to start all over again, but even after zeroing the superblocks on all three disks, and creation of a new array, /proc/mdstat shows the same drive numbers, while reconstructing the third drive.
What should I do ?
