Hello

After reading my post I realized I had some typos. 

> 
> <chunksize> <= 1024kB/4; either 256k, 128k, 64k 
> 256k = <      = 1024k/4k

This was supposed to be 128k per the raid6 configuration


> 
> <chunk_blocks> = <chunksize(decided above)> / 4k
> 32 = 256/4 

This was supposed to be 
32 = 128k/4k

> 
> 128k = 512k / 4k
> <stripe_width_blocks> = <stripe_width> / 4k

I should have waited until I was awake to send this out.
