<p class=MsoNormal>Hi all,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’m new to this list and fairly new to pacemaker and
have just spent a couple of days trying unsuccessfully to solve a configuration
challenge.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have seen a relevant post on this list from around four
years ago but it doesn’t seem to have helped – here’s what I
want to do.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have 389 directory server running on two Centos servers.
It’s configured for MMR and my plan is to use one replica as the primary
LDAP server, failing over to the secondary only if there’s a problem.
This is to avoid frequent writes to both replicas causing high levels of
bi-directional replication traffic. SO I’m looking for failover rather
than load balancing.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>This works fine using a traditional load balancer configured
appropriately for weighting and stickiness with a simple heartbeat to the LDAP
server but I’d like to see if I can use Pacemaker instead using a
floating IP across the two LDAP servers and appropriate monitoring to control
switch over.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’ve configured a floating IP resource OK but am
struggling with the question of how to monitor the 389 server.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>If I create a resource using lsb:dirsrv then I find that the
server is started up on the primary cluster node but not on the second –
which is understandable but not what I need.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>What I would like to be able to achieve is to have the 389
instances monitored but not controlled such that the floating IP address switches
across when required but without stopping or starting the 389 instances.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Right now I’m not sure whether I should be using the
dirsrv resource or looking for some kind of simple ‘LDAP ping’
resource that could be used.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Any advice would be hugely appreciated.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Kind regards,<o:p></o:p></p>
