What issues should be expected if running multiple AFR instances on
the same storage bricks?
For example, 3 nodes; each node has a storage volume and two clients
connecting to the other 2
nodes; with an AFR volume across the nodes:

volume brick1
type storage/posix
...
end-volume
volume client1
type protocol/client
...
end-volume
volume client2
...
end-volume
volume afr
