ConquerorHi slaweq, how are you? I want to inform you I had fixed neutron problem :) If you recall I was talking about classless-static-route... The machines with the neutron-dhcp-agent ervice are missing the force_neutron parameter. I had set the force_neutron is True in ini files, even the restarting neutron-dhcp-agent services, everything works properly. The classless-static-route definition now always shows the dhcp-agent ip.08:13

eanderssonIs there a recommendation for the number of dhcp agents per network?22:29
*** jenglisch_ has joined #openstack-neutron22:30
eanderssonIs there a side-effect with running a higher number?22:30
haleybeandersson: there is no hard rule for dhcp agents, but we typically don't run more than 322:32
eanderssonWe are struggling with dhcp keeping up at the moment, and was hoping there would be a knob we could tweak22:32
haleybeandersson: keeping up?22:33
eanderssonWith the creation of new ports22:33
eanderssone.g. if we create a larger number of VMs it can take minutes for leases to get created22:34
eanderssonWe also have issues just restarting the dhcp agent22:34
haleybthat might be faster in Stein, we introduced a few changes that should help22:34
*** ijw has joined #openstack-neutron22:34
eanderssonWe are bound by a vendor driver and probably won't be able to go to Stein anytime soon :'(22:35
eanderssonWe are running the very latest version of Rocky thou (with one of the more major changes to the dhcp agent)22:35
eanderssonThere is one thing in particular that is weird22:36
haleybwe might have backported some of the changes too, just not everything, Rocky might have most22:36
eanderssonWhen we restart the dhcp agent, unless we set the RPC timeout real high, it never really finishes syncing22:36
eanderssonIt tries to sync all ports, but neutron takes too long, so it just starts over and over22:37
haleybit's going to ask for everything at startup, i've seen that failure before, you might want to increase the number of rpc workers in your neutron server22:37
eanderssonWe tried to massively scale taht22:38
eanderssonLike massively22:38
eanderssonDid not help22:38
eanderssonIt looks like the dhcp agent is just doing them one-by-one22:38
eandersson32x2 + 16x2 rpc workers is what we tried22:39
haleybthe dhcp-agent should be using 8 workers, but like i said, there might be some other things not in Rocky.  i wouldn't think any number of rpc workers over 24 is good, i can't remember our last tuning try22:40
eanderssonYea - I mean that was just to make sure it wasn't a scale issue.22:41
eanderssonIt's not actually what we are running.22:41
haleybeandersson: https://review.opendev.org/#/c/649573/ might help, don't know if you have that one, but i guess we did backport it22:42
eanderssonYea - actually got that one.22:43
eanderssonIt does not fix the startup issue, but haven't had time to do a scale test with VMs yet.22:43

*** rcernin has joined #openstack-neutron22:45
haleybeandersson: oh, and you had reviewed https://review.opendev.org/#/c/641490/ which is not in Rocky, so you're probably pretty close code-wise to Stein22:46

eanderssonCPU Load went up exponentially when upgrading from Mitaka to Rocky for us22:48
eanderssonNot quite sure where that load is coming from22:48
eanderssonWe have doubled the hardware of the control plane, and we are still seeing slightly higher average cpu usage22:48
