[Gluster-users] Replicated with bricks of different sizes

[Adam Tygart]

As a short-term placeholder it should be fine. However, we all know
how things designated short-term can tend to become less so.

The real problem would occur when the smaller server gets filled up.
In theory, gluster would drop into a read-only mode. In theory, there
is no difference between practice in theory. In practice, there often
is.
