Lookups (and writes of course) from clients are sent to both bricks
because AFR uses the result of the lookup to select which brick to read
from if there is a pending heal etc.
If the file is clean on both A and B, then reads are always served from
the local brick. i.e. reads on clients mounted on A will be served from
the brick in A (and likewise for B).
Hope that helps,
