Thank's for your suggestion, I'ld try this as a last resort. First I have to look for some spare 16TB...
Do You really think, the stripe size of a hardware raid does matter to LVM alignment algorithms?
I peeked into /sys and /proc but I didn't find any exposure of this value to the system at all.

But anyway, thanks!
