I know this has come up before, but a few quick googles hasn't answered my
questions - I'm after the max. array size that can be created under
bog-standard 32-bit intel Linux, and any issues re. partitioning.

I'm aiming to create a raid-6 over 12 x 500GB drives - am I going to
have any problems?

(I'm not parittioning the resulting md device, just the underlying sd
devices and building a single md out of  sd[a-l]4 ...)

Cheers,

Gordon
