<p class=MsoNormal>Hi all, could you advise please?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’m trying to configure a floating IP with an active/active
deployment of 389 directory server. I don’t want pacemaker to manage LDAP but
just to monitor and switch the IP as required to provide resilience. I’ve seen
some other similar threads and based my solution on those.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’ve amended the ocf for slapd to work with 389 DS and this
tests out OK (dirsrv).<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’ve then created my resources as below:<o:p></o:p></p>
