Off-email question: If a volume has N read replicas, how do clients
choose which one to use?
By default, it's effectively random. Technically the client also takes
into account the ip addresses of the client and server to try and
estimate how "close" it is to each fileserver, but it does so using
antiquated classful addressing techniques and usually isn't very useful.
Er, I would have thought that this would cause a group of clients
deployed near each other to all prefer the same replica, which is not
really "random". That is, though from the point of view of a single
client the choice may be random, from the point of view of managing
server load it is not. Is that incorrect?
IMHO on the windows client there is a serverprefs based on RTT. And that
is planned to go into linux client, to.
