First of all, we are currently only supporting 4K filesystem block size, so
for now you should use this. I don't really have a hard and fast answer for
what would behave best for small files, since at SGI striped file systems
usually go together with big I/O. But I would try 8K for now.

p.s. how goes the mkfs issue?
