| lxkong | johnsom: could you please have a look at https://review.openstack.org/#/c/599467/? The member address validation is missing for graph lb creation. | 02:31 |
| lxkong | which is urgent for us | 02:32 |
| johnsom | lxkong Ok, thanks for letting me know it is urgent. It's a bit busy for me right now. I will try to take a look soon | 02:34 |
| lxkong | johnsom: appreciate. After this is merged, I can continue to fix the batch member update function. | 02:35 |
| johnsom | Ok cool. Yeah, glad to see more validations | 02:35 |
| lxkong | BTW, for batch member update function, i found a bug here https://storyboard.openstack.org/#!/story/2003608 | 02:35 |
| johnsom | Yeah, that is an odd one. Are you working on that? | 02:41 |
| lxkong | johnsom: not yet. Currently I am dealing with our octavia related tickets in our production | 02:58 |
| lxkong | and octavia support in various orchestration tooling support, gophercloud, ansible, etc. | 02:59 |
| lxkong | johnsom: fyi, ansible support here https://github.com/ansible/ansible/issues/41829, and most of octavia functionality for gophercloud has been merged. | 03:00 |
| johnsom | yeah, I'm still working at 8pm on a nasty bug.... | 03:00 |
| johnsom | lxkong Excellent! | 03:00 |
| johnsom | Do we have that on our SDK list? | 03:00 |
| lxkong | johnsom: didn't check :-( | 03:00 |
| johnsom | Yeah, it's there | 03:01 |
| lxkong | i guess gophercloud is on the list, but ansible is not | 03:01 |
| johnsom | https://docs.openstack.org/octavia/latest/user/sdks.html | 03:01 |
| lxkong | there are still some modules i'm working on | 03:01 |
| lxkong | currently, the graph creation support | 03:01 |
| johnsom | Yeah, ansible is one of the deployment tools. It will be on that list once I write the install guide.... sigh | 03:01 |
| lxkong | after the basic modules are done, i will let you know | 03:02 |

| jiteka | Hello, I have a question regarding spare pool feature and the fact that it's not compatible with anti-affinity at the moment | 14:42 |
| jiteka | 1. Are you currently discussing possible solution to have both compatible ? | 14:42 |
| jiteka | 2. If I still decide to keep using ACTIVE_STANDBY topology with anti-affinity, and end-up in case where both MASTER and BACKUP are on the same compute, | 14:42 |
| jiteka | Is it possible to disable spare pool then failing over one of the amphora to ensure anti-affinity ? | 14:42 |
| *** yboaron_ has quit IRC | 14:43 | |
| *** dolly has quit IRC | 14:50 | |
| *** Swami has joined #openstack-lbaas | 14:50 | |
| johnsom | jiteka I believe that if you have spares pool enabled it simply will not be used for failover. Basically we didn't want to get into the scheduler business and nova doesn't handle "adding" booted instances to an anti-affinity server group. | 14:52 |
| jiteka | johnsom: spare pool is only used for new loadbalancer ? | 14:55 |
| johnsom | In active/standy topology mode, I think that is correct | 14:56 |
| johnsom | But it might be disabled there too due to the same issue adding booted instances to the server group | 14:56 |
| johnsom | It's been a while since I have looked at that code. | 14:56 |
| jiteka | johnsom: I'm gonna perform some testing on that as I want to see if I can use spare pool and still have some Ops way to remediate to VIP with degraded HA due to MASTER and BACKUP living on the same compute | 14:57 |
| johnsom | jiteka You could open a Nova RFE to update the server group anti-affinity to support live migration or some other way of adding a node to a existing server group. If we had a way to do that reliably without requiring us to become a scheduling engine it would be best. | 14:59 |
| johnsom | jiteka I think to date, we haven't had anyone that truely needed the performance of spares pool when running active/standby, so it hasn't been a focus for us. | 14:59 |
| *** celebdor has quit IRC | 15:00 | |
| johnsom | jiteka Would be good to get a story in for Octavia too, with your use case. Maybe we can get creative and go through the spares pool attempting to add them to the server group. I'm not sure if Nova will give us a useful exception that we could attempt to keep trying spare instances or not. Maybe it would just cycle through the list and force a boot anyway. | 15:05 |
| jiteka | johnsom: unfortunately right now live-migration is not an option as we rely on flavor with vCPU pinning and NUMA, and nova-scheduler is not aware of NUMA topology and vCPU pinning when live-migrating on a targeted host leading to overlap vCPU and degraded performance | 15:08 |
| johnsom | Gotcha | 15:08 |
| johnsom | Fnacy | 15:08 |
| johnsom | Fancy | 15:08 |
| johnsom | So when you allocate a vCPU you actually mean it... ha | 15:09 |
| jiteka | johnsom: that's why performing regular audit on amphora fleet to solve LB not fullfilling anti-affinity would do the trick | 15:09 |
| jiteka | johnsom: will do some testing in devstack and in our pre-prod environment then see my options | 15:10 |
| jiteka | johnsom: thanks for the precision :) | 15:11 |
| xgerman_ | jiteka: what you want sounds like soft-anti-affinity | 15:11 |
| jiteka | xgerman_: I saw that option but I don't really understand the difference between "soft" and "normal" anti-affinity | 15:11 |
| xgerman_ | we “could” add a case if you specify soft that we use the spare pool for failover knowing you might end up on the same server | 15:11 |
| johnsom | They are nova terms. xgerman_ is probably describing them as I type this.... | 15:12 |
| jiteka | xgerman_: I had the feeling that soft-anti-affinity is a best effort as it will try to ensure anti-affinity without failing the build with NoValidHost exception if there is no available hypervisor that would be compliant with that filter | 15:12 |
| xgerman_ | yeah, and we *could* enhance Octavia to use spare pool if you specify soft — since then you signal you tolerate being on the same “server" | 15:13 |
| johnsom | Yeah, soft anti-affinity is "best effort" to not co-locate the amps on the same host, but if there is no other option in the cloud, go ahead and schedule the nova instance to the same compute host. | 15:14 |
| xgerman_ | yep, which would make using spare pool legit | 15:14 |
| xgerman_ | though probably not what jiteka wants ;-) | 15:15 |
| jiteka | xgerman_: indeed, it's not exactly what I have in mind as HA and ensuring that losing an hypervisor won't end-up with a VIP going down because both amphora were running here, sounds to me like good Ops practice | 15:16 |
| rm_work | cgoncalves: ah thanks :P missed dolly I guess | 15:17 |
| jiteka | xgerman_: ideally having some LB flavor and choosing between, expendable LB that tolerate same host and downtime VS Critical LB that need to stay reachable at any time | 15:17 |
| jiteka | xgerman_: would be better | 15:17 |
| xgerman_ | well, that plays with our Stein goal of flavors ;-) | 15:18 |
| rm_work | yeah that basically sounds like not having any anti-affinity | 15:19 |
| rm_work | because it will basically just be random | 15:19 |
| rm_work | which is ... exactly as good as not having it at all | 15:19 |
| jiteka | is it possible to have 2 different octavia provider ? (with different configuration) | 15:20 |
| jiteka | I mean 2 loadbalancing provider | 15:20 |
| rm_work | sure | 15:20 |
| rm_work | i believe so | 15:21 |
| jiteka | which both would be octavia but with 2 separated control plane | 15:21 |
| rm_work | oh hmmm | 15:21 |
| rm_work | i'm ... not actually positive how that'd work | 15:21 |
| rm_work | i guess i'm thinking about flavors | 15:22 |
| jiteka | rm_work: was thinking about that when you don't have flavor but it solve the same problem | 15:22 |
| johnsom | Yeah, might just be worth waiting for flavors. I think you will run into DB problems trying to run two Octavia amphora based provider drivers | 15:24 |

| rm_work | yeah, i think really it's fine to have no spares pool if your cloud isn't SUPER slow | 17:19 |
| rm_work | ~1m boot time should be achievable and then whatever | 17:20 |
| rm_work | yeah, 1m to create a LB isn't GREAT but it's not horrible | 17:20 |
| rm_work | and rebuilding a backup at ~1m is fine | 17:20 |
| rm_work | though, AZ-anti-affinity is :P:P | 17:20 |
| rm_work | actually i had intended to do host internally as well | 17:21 |
| rm_work | <_< | 17:21 |
| rm_work | but it's a little more complex, and probably no one would want to actually include THAT low level in octavia | 17:21 |
