Re: Linux nvraid 0+1 question
I don't think that's quite it. Here's the scenario as I understand it. The data would look something like:
1 2 3 4 5 6
A1 A2 A3 A1 A2 A3
A4 A5 A6 A4 A5 A6
If we call the disks 1 to 6, from left to right (since my chart probably won't line-up,) the way it currently reads the data is.
1: A1, A4
2: A2, A5
3: A3, A6
It would be about twice as fast to do:
With this set up six blocks could be read simultaneously instead of three. Or is the thought that reading from the backup disks increases their chances of failure?
