So I've been slowly expanding my knowledge of mdadm/linux raid.

I've got a 1 terabyte array which stores mostly large media files, and
from my reading, increasing the stripe size should really help my
performance

Is there any way to do this to an existing array, or will I need to
backup the array and re-create it with a larger stripe size?

Backup the array and re-create it is currently the only way with sw
raid AFAIK..

Yep, but I think increasing the readahead should do almost the same  
without having to re-create the RAID.
See http://hep.kbfi.ee/index.php/IT/KernelTuning for instructions.
Happy new year everyone!
