<p class="MsoNormal">Hi folks,<o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Currently there are two attributes of vips/pools/members that represent a status: 'status' and 'admin_state_up'.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">The first one is used to represent deployment status and can be PENDING_CREATE, ACTIVE, PENDING_DELETE, ERROR.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">We also have admin_state_up which could be True or False.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I'd like to know your opinion on how to change 'status' attribute based on admin_state_up changes.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">For instance. If admin_state_up is updated to be False, how do you think 'status' should change?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Also, speaking of reference implementation (HAProxy), changing vip or pool admin_state_up to False effectively destroys the balancer (undeploys it), while the objects remain in ACTIVE state.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">There are two options to fix this discrepancy:<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">1) Change status of vip/pool to PENDING_CREATE if admin_state_up changes to False<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">2) Don't destroy the loadbalancer and use HAProxy capability to disable frontend and backend while leave vip/pool in ACTIVE state<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Please share your opinion.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
