I don't know the answer, but let me know when you figure it out. ;) I'd
guess the first option would be best, since only one master will be receiving
the writes as well, since you'll be using mirror mode.
1) On each replica, create a single syncrepl stanza that points to the
load balancer VIP.
2) On each replica, creates two syncrepl stanzas, each one pointing to
a different master.
I'm inclined to agree; if you're going to have some mechanism set up (as
you must for mirrormode) to ensure that writes only go to one server, I
believe it would make the most sense to use that same mechanism for
replica determination. If your writes are (mis)directed, it'd make sense
for your replicas to be similarly (mis)directed.
