<p class="MsoNormal">Hi all<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Here pool was created successfully but my load-balancer stuck in PENDING_UPDATE state in both Neutron & Octavia databases.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When I tried to delete pool I got error saying that pool can not be deleted because respective load-balancer is in immutable state. Ok fine.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">After some time ( after around 1 hr) load-balancer in Neutron DB had become ACTIVE state , but in Octavia DB still in PENDING_UPDATE state.<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This is a bug right ? This bug a raised as load-balancer-state is not in synch in Neutron DB and Octavia DB. <o:p></o:p></p>
<p class="MsoNormal">This in synch is coming because load-balancer state becomes ACTIVE from PENDING_UPDATE automatically. Is this expected behavior ?
<o:p></o:p></p>
<p class="MsoNormal">How can we make load-balancer state should be in synch in both the DBs.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
