Why should I be reading FreeBSD man pages when this is a Linux list? I 
am using the terms stripe size and chunk size in the sense I understand 
them, which is I believe the Linux sense. If you and FreeBSD choose to 
use the terms differently, so be it, but please don't pull me up about 
my use of terms when you're the one using the wrong ones in this context.

I'll concede, only all the major filesystems you'd ever use in a 
production environment.

Not a problem, the same mechanisms by which filesystems can be aware of 
RAID means filesystems are aware of LVM and LVM is aware of RAID.

There's absolutely no need for that. Please leave, and take your 
condescension, ignorance and offensiveness with you.
