Hi!
I’m trying to setup a cross DC setup with one master and two slaves.
Servers are:
Sc0b03 => master
Pr0b03 => slave 1
Sp0b03 => slave 2
The relevante configuration is:
On Master server:
<connectors>
<connector name='sc0b03'>tcp://sc0b03:61616</connector>
<connector name='pr0b03'>tcp://pr0b03:61616</connector>
<connector name='sp0b03'>tcp://sp0b03:61616</connector>
</connectors>
<cluster-user>xxxxxx-user</cluster-user>
<cluster-password>xXxXxXxXxXxXxXxXxX</cluster-password>
<ha-policy>
<replication>
<master>
<check-for-live-server>true</check-for-live-server>
</master>
</replication>
</ha-policy>
<cluster-connections>
<cluster-connection name="my-cluster">
<connector-ref>sc0b03</connector-ref>
<static-connectors>
<connector-ref>pr0b03</connector-ref>
<connector-ref>sp0b03</connector-ref>
</static-connectors>
</cluster-connection>
</cluster-connections>
On each Slave (Sp0b03):
<connectors>
<connector name='sc0b03'>tcp://sc0b03:61616</connector>
<connector name='pr0b03'>tcp://pr0b03:61616</connector>
<connector name='sp0b03'>tcp://sp0b03:61616</connector>
</connectors>
<cluster-user>xxxxxx-user</cluster-user>
<cluster-password>xXxXxXxXxXxXxXxXxX</cluster-password>
<ha-policy>
<replication>
</replication>
</ha-policy>
<cluster-connections>
<cluster-connection name="my-cluster">
<connector-ref>sp0b03</connector-ref>
<static-connectors>
<connector-ref>sc0b03</connector-ref>
<connector-ref>pr0b03</connector-ref>
</static-connectors>
</cluster-connection>
</cluster-connections>
What happens:
Only one replication (Pr0b03) appears at console:
Cluster Info<http://mq.simfrete.com/console/>
Lives: 1
Backups: 1
HA Policy: Replicated
replicating: true
I’m sure that all servers can touch each other in port “61616” (I’ve used
telnet to test all of them), and log of servers “Pr0b03” and “Sp0b03” are
exatcly equals – respected their address diferences.
And I’m sure that if I stop “Pr0b03” then “backups” return to 0.
Relevant startuplog at Sp0b03:

Am I correct on supposing it is possible to have 2 bakckups for one master?
All tips and tricks will be welcome!
