Hi all,

I got a little confused about the various chunk/stripe sizes when
using mdadm in combination with LVM.
I searched the mailing list archives and googled it but couldn't
really find a definite answer to my question.

I'm searching for the most optimal chunk/stripe sizes using mdadm and LVM.

It would seem you're one of the countless we see here with hardware,
real or imaginary, who has no workload, or is seeking a workload for his
hardware.  This is the wrong approach.

You need to approach this list with:

1.  This is my workload
2.  This is the hardware I currently have (suitable or not)
3.  How do I best setup my storage to meet my workload requirements?

You're approaching this backwards.
