Actually, after posting it I had the brilliant idea of searching the
archives a bit further.
Here is an advice I found from Krishna:
"In case you have 4 machines each with 4 drives.
you can replicate each drive of server1 with corresponding drive of
server2 using AFR.
you can replicate each drive of server3 with corresponding drive of
server4 using AFR.
So you have 8 AFRs.
You can use distribute (aka DHT) to aggregate the 8 AFRs."
So basically the idea was to divide all the servers to pairs, then AFR each
drive in the pair, and then unify/dht all the AFR's in a single volume.
Is this the only approach, or there are other ones?
Because the main downside of this approach seems to me, as the need to
update all the config files on all the participating servers and clients.
