sapd | hi johnsom , does this change related my issue https://github.com/openstack/octavia/commit/48e85569f7e43e3dd5f09fd1ef4cb165526a92cd#diff-bca5cd1020cb0a80eee6beb9f45c8d55? | 02:21 |

sapd | my previous issue: http://paste.openstack.org/show/723774/ | 02:22 |
johnsom | sapd: It might be if you are running master/Rocky code | 02:39 |
johnsom | There was a race condition introduced with the provider driver work. | 02:39 |
johnsom | There are two patches to address those, one for create and one for updates | 02:40 |
sapd | yep. I'm running on this commit https://github.com/openstack/octavia/commit/1a807242bac4095ee2eebd6dda0520195fe5ab64 | 02:41 |
sapd | I will update source code and test again | 02:42 |

devfaz | johnsom: jet again, sorry! | 08:19 |
devfaz | rm_work: Im currently using pike, octavia 1.0.2 | 08:21 |
devfaz | What I already found is that the number of threads octavia-health is using is increasing. Currently each process is using 1800 threads and I restarted the process yesterday. Im able to reproduce this by starting some lb and wait. The amounts of threads is increasing over time. | 08:23 |

johnsom | devfaz: event streamer is only used if you are using neutron-lbaas. It will backup threads if it is enabled and the rabbit queue for it is not configured. Disabling it is the best answer. | 13:48 |

devfaz | johnsom: hmm, i still need neutron-lbaas, because heat is in pike not able to use octavia directly isnt it? So i have to check my configuration. | 19:32 |
johnsom | I know heat supports octavia, but I'm not sure which release they added it in. | 19:32 |
devfaz | rm_work: yes, the threads are increasing issue is still in master, if that what you wanted to know? | 19:33 |
rm_work | hmmm ok | 19:33 |
rm_work | devfaz: if you are running octavia master, you can do an L7 redirect and skip neutron-lbaas entirely and it will "just work" | 19:33 |
johnsom | Yes, good point | 19:34 |
devfaz | Good idea! I will try it out | 19:34 |
rm_work | on the LB in front of your neutron API, you can redirect /lbaas/ to octavia's endpoint | 19:34 |
rm_work | see: https://review.openstack.org/#/c/561049/ | 19:34 |
rm_work | https://review.openstack.org/#/c/561049/38/devstack/etc/neutron/haproxy.cfg | 19:34 |
rm_work | this is proven to work :) | 19:35 |
rm_work | BTW can we review/merge that? | 19:35 |
devfaz | :) | 19:35 |
*** yamamoto has joined #openstack-lbaas | 19:36 | |
*** AlexeyAbashkin has quit IRC | 19:37 | |
devfaz | Maybe someone is able to answer an other question. I lost some Amphore - LB mappings in the past and the database already got cleaned. Now im looking for a way to recreate the missing amphora. Most of the remaining are masters, but even an lb-failover will just recreate the master without doing any Backup-amphora recreation. Any ideas? | 19:38 |
rm_work | yeah | 19:39 |
rm_work | so what I do, is copy the master record, and just make up random uuids for the compute_id and all of the port id fields | 19:39 |
rm_work | and let it assign a new uuid for the uniqueid | 19:39 |
devfaz | Perfekt thx! | 19:39 |
rm_work | and mark that as BACKUP | 19:39 |
rm_work | and then do a failover on it | 19:39 |
rm_work | the newest code makes that much less likely to happen, so that is good | 19:40 |
rm_work | (it doesn't clean up the records so quickly) | 19:40 |
johnsom | rm_work do we have a bug on that? Do we know why? | 19:40 |
rm_work | johnsom: it's fixed | 19:40 |
rm_work | when failovers fail ... the records get wiped like instantly in the old code | 19:40 |
rm_work | because it doesn't have an expiry for the amps | 19:40 |
johnsom | Ok. I know the dual amp failure ends in something like this, which is what I am working on right now | 19:41 |
rm_work | it's a bit different | 19:41 |
rm_work | it's just the record being deleted out from under you like, instantly | 19:41 |
rm_work | happened to me a lot before | 19:41 |
*** blake has quit IRC | 19:41 | |
johnsom | Ok, yeah, I remember that now | 19:41 |
rm_work | which is why i made sure to do https://review.openstack.org/#/c/548989/ | 19:41 |
*** blake has joined #openstack-lbaas | 19:42 | |
*** yamamoto has quit IRC | 19:42 | |
xgerman_ | yeah, we also have that neutron proxy plugin which is now more than a year in development… | 19:45 |
*** blake has quit IRC | 19:47 | |
*** aojea has joined #openstack-lbaas | 19:48 | |
rm_work | xgerman_: and yet still strikes me as only necessary if you're stuck on an older version of octavia that wasn't fully API compatible <_< | 19:52 |
rm_work | for anyone who can run master / Rocky, it is *significantly* simpler and less moving parts to just do the L7 redirect | 19:52 |
rm_work | they have distinctly different uses IMO | 19:52 |
*** salmankhan has joined #openstack-lbaas | 19:53 | |
xgerman_ | well, I just did what we agreed to in Atlanta and then things got slow walked | 19:59 |
rm_work | i think we revised our thinking :P | 20:03 |
rm_work | that said, I don't think the work was wasted | 20:03 |
rm_work | for anyone stuck on pike/queens, you probably need that method | 20:04 |
rm_work | but i don't think it's something we should be advising people use going forward, if they are able to run rocky+ | 20:04 |
rm_work | basically, if Octavia<=Queens: use proxy plugin, if Octavia>=Rocky: use L7 redirect if possible | 20:05 |
rm_work | it's also possible there are cases where people can't do L7 stuff in front of neutron | 20:05 |
rm_work | in which case, they'd also need the plugin | 20:05 |
devfaz | rm_work: if I remember correctly, it should be fine to run octavia master in an pike cloud, isn't it? | 20:05 |
johnsom | yes | 20:05 |
rm_work | yep | 20:06 |
rm_work | I run octavia master on a Liberty cloud <_< | 20:06 |
johnsom | Like a crazy man | 20:06 |
rm_work | (I couldn't find a Juno or Kilo cloud to use instead) :P | 20:06 |
rm_work | I *think* it'd ork | 20:07 |
rm_work | *work | 20:07 |
devfaz | Ok, then I have enough to do tomorrow. Thanks a lot for your work and help! | 20:07 |
