| johnsom | I guess we already had an etherpad. I can update their links page with our page: | 16:00 |

| rm_work | johnsom: did we fix the nova-hv-down issue? assuming running on master, and an amp's HV is down and stays down, can we failover the LB currently? | 19:06 |
| rm_work | i don't remember if we did a fix, or if someone is still working on making it better, or both | 19:06 |
| johnsom | rm_work That is part of the failover flow fix I'm working on | 19:14 |
| rm_work | k | 19:15 |
| rm_work | i thought we might have also put in a hotfix or something that'd workaround the issue somewhat... | 19:15 |
| johnsom | There is an open nova bug for it (and one for storage) | 19:15 |

| colin- | quick question, in a normal loadbalancer failover flow, why does the BACKUP not takeover MASTER during the period of time it is the only existing amp? (no spares pool, ~1m boot times) | 20:33 |
| johnsom | It does, but note, the DB is what the SETTING is, not the current state. | 20:33 |
| colin- | ohhh | 20:34 |
| colin- | cisco used to do this with their HA, Active/Standby vs Primary/Secondary | 20:34 |
| colin- | that tripped me up for years | 20:34 |
| *** pcaruana has joined #openstack-lbaas | 20:34 | |
| colin- | got it. thx | 20:34 |
| johnsom | Yeah, it seems to catch most folks. We discussed changing the column name, but pretty much nothing would solve it.... | 20:34 |
| colin- | in this sense 'role' is actually most appropriate i think. 'status' or something more ephemeral would be what i was thinking of | 20:35 |
| colin- | (who currently has the VIP) | 20:35 |
| johnsom | Right. Plus the amps can failover much faster than we would update the DB.... They are autonomous at that layer of the HA pie | 20:36 |

| rm_work | I had a system that caused them to actually update ;D | 21:07 |
| rm_work | so in my deployment at GD, those columns were updated to always be accurate | 21:07 |
| * rm_work shrugs | 21:07 | |
| rm_work | we could still do that I think | 21:07 |
| rm_work | if we wanted | 21:08 |
| rm_work | it's just informational, so we could do best-effort updates for it | 21:08 |
| rm_work | but that might be more confusing if it worked "most of the time" than just not doing it at all | 21:08 |
| rm_work | hmm actually i think i know a way to make it always update, theoretically | 21:08 |
| johnsom | Right, I think the confusion and effort would out-weight the benefit. | 21:08 |
| rm_work | I just don't know how it would impact some of our other flow stuff | 21:08 |
| rm_work | the issue was that keepalived didn't really have a way to query to ask if it was currently acting as master or not | 21:09 |
| rm_work | and also the case of split-brain where both can access the controller | 21:09 |
| rm_work | because we COULD track it ourselves using the notify scripts to drop a flag somewhere and then adding that amp status to the UDP health message | 21:10 |
| johnsom | Plus if something is really borked and it's switching like every second, are we just making the cloud bork worse.... | 21:10 |
| rm_work | but I feel like then it'd be much more common to have weird states (hopefully but not guaranteed to be temporarily) where there's two MASTER or BACKUP | 21:10 |
| rm_work | and how that would affect other long-failover stuff... | 21:11 |
| rm_work | i've given it a bit of thought, and there's no COMPLETELY clean way to do it, AFAICT, though there's some options that might be worth the tradeoffs, maybe | 21:11 |
| johnsom | Personally, I perfectly happy to say "It's autonomous, it changes on it's own in reaction to failures." | 21:12 |
| johnsom | We could also call it "Quantum HA", it exists in both states, all of the time. | 21:12 |
| johnsom | lol | 21:13 |
