<p class=MsoNormal>Hi,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>We are using RabbitMQ in a Pacemaker/corosync HA
cluster. Our current implementation is very basic: Pacemaker manages the
rabbitmq server as a resource, and we have a floating IPAddr2 resource that is
grouped with it. The single floating IP address is a requirement of our
system.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’ve been reading the mirrored queue article, and have
a few questions.<o:p></o:p></p>
<p class=MsoListParagraph style='margin-left:.75in;text-indent:-.25in;
mso-list:l1 level1 lfo2'><![if !supportLists]><span style='mso-list:Ignore'>1)<span
style='font:7.0pt "Times New Roman"'> </span></span><![endif]>Are
the master/slave broker nodes managed by Pacemaker (or some similar HA system)
to bring the nodes into service and/or restart in the case of failure? Does
the master/salve term refer to the broker nodes (i.e. A Pacemaker Stateful
resource) or only the mirrored queues?<o:p></o:p></p>
<p class=MsoListParagraph style='margin-left:.75in;text-indent:-.25in;
mso-list:l1 level1 lfo2'><![if !supportLists]><span style='mso-list:Ignore'>2)<span
style='font:7.0pt "Times New Roman"'> </span></span><![endif]>It
appears that the consumer client can connect to any broker, and if it is
consuming from a mirrored queue, it effectively is consuming from the master
node. I.e., A client can have a connection open to any broker node in the
rabbitmq cluster, but effectively is still consuming from the master node of a mirrored
queue. Is that understanding correct?<o:p></o:p></p>
<p class=MsoListParagraph style='margin-left:.75in;text-indent:-.25in;
mso-list:l1 level1 lfo2'><![if !supportLists]><span style='mso-list:Ignore'>3)<span
style='font:7.0pt "Times New Roman"'> </span></span><![endif]>Does
the server have support for floating IP addresses in 2.7.1? (The 2.4.0
behaviour seems to be that the server will only bind to an IP address at
startup. If the IP address becomes valid later, as in the floating IP
case, the server can’t see it.)<o:p></o:p></p>
<p class=MsoNormal>Thanks,<o:p></o:p></p>
