Slave Fail-over in a static cluster
I have 3 master nodes and 3 slaves. I have 2 brokers in each of the 3 VM
instance, and one is a master and the other is a slave. Total 6 brokers.
The current configuration is such that M1, M2, M3 - S1, S2, S3 i.e.
Master1's slave is S2, which is in VM2. So, in case one VM goes down, the
slave will be on the other VM.
However, I notice a peculiar behavior, where the slaves assign different
masters than what they're configured to do so. What I mean is, for example,
on M1's config, I have M2, M3 and S2 in a cluster. In S2's config, I have
only M1 as a connector reference.
Let me know if this is intended, else I'll post my broker configuration.
Thanks guys! :)

Awesome as usual! I'll give it a try and see how it works out!

Hey Justin, so if I have 3 master nodes and 3 slave nodes, should I have all
the 5 nodes in each broker's static connectors, or only the masters + 1
slave (same group) would do?

Take a look at the documentation for replication [1], specifically the
"Data Replication" section. It discusses the "group-name" configuration
parameter which is what I believe you want.
You'll find there's lots of helpful things in the documentation. :)

Please keep in mind that Master 1's intended slave is Slave2. Master2's
slave is Slave 3 and Master3's slave is Slave1.

It's a replication HA. On what basis does a master and slave pair together
then?

What kind of HA have you configured (i.e. replication or shared-store)?
The cluster connection configuration doesn't define how masters and slaves
pair together.
