Hi,
I created a a distribute stripe with 12 nodes, each with one brick. I
expected 6 pairs to be striped with the large files but what I see on
the actual brick is each file duplicated, ie. mirrored. This is the
complete opposite of what I expected. I expected half the large file
on one server and half on the second server. This is to allow for
file sizes larger than an individual brick capacity.
Is my configuration broken/misconfigured or am I completely
misunderstanding what I see happening?

They're sparse files, only actually holding the stripes assigned to them.
