ltomasbo | apuimedo, I tried your script to create the port, and I'm still seeing the bug: https://bugs.launchpad.net/neutron/+bug/1696051 | 07:25 |
openstack | Launchpad bug 1696051 in neutron "Missing binding details for bulk port creation requests" [Undecided,New] | 07:25 |
ltomasbo | apuimedo, http://paste.openstack.org/show/622281/ | 07:25 |
ltomasbo | even though if I later do a port show, those details are there: | 07:25 |
ltomasbo | | binding_vif_details | datapath_type='system', ovs_hybrid_plug='True', port_filter='True' | | 07:25 |
ltomasbo | | binding_vif_type | ovs | 07:25 |
ltomasbo | apuimedo, good thing is that those ports are being recovered upon controller reboot | 07:28 |
*** aojea has quit IRC | 07:30 | |
*** egonzalez has joined #openstack-kuryr | 07:44 | |
apuimedo | ltomasbo: ah! You meant about the creation answer? | 07:53 |
apuimedo | Well, it doesn't matter, immediately after they have the details | 07:54 |
ltomasbo | apuimedo, yes | 07:54 |
apuimedo | don't they? | 07:54 |
ltomasbo | sure, but you need to do another get then | 07:54 |
ltomasbo | apuimedo, it just annoyed me that if you do a normal creation of a port, it has that information | 07:55 |
ltomasbo | but if you do a bulk creation of a single port, then it is not there | 07:55 |
*** gilfoyle has joined #openstack-kuryr | 07:56 | |
ltomasbo | and we had to add a workaround due to that: https://github.com/openstack/kuryr-kubernetes/blob/master/kuryr_kubernetes/controller/drivers/neutron_vif.py#L59-L66 | 07:56 |
apuimedo | ltomasbo: about that workaround... Probably a second get is faster than the single port creation | 07:58 |
ltomasbo | yes, but not sure if we will always have that information in the second get or we may end up in a race | 07:59 |
ltomasbo | anyhow, I can do a while with sleep 1 or so, with a few tries | 07:59 |
apuimedo | ltomasbo: mmmm | 07:59 |
apuimedo | I think it's better to check if there is a race or not | 07:59 |
apuimedo | ltomasbo: however, what worries me is the cni timeouts I was seeing yesterday on baremetal that make PLEG put the node as not ready | 08:00 |
apuimedo | since livelace-link also reported it | 08:00 |
*** gilfoyle has quit IRC | 08:01 | |
ltomasbo | yes, that is a hard problem | 08:01 |
ltomasbo | apuimedo, do you know if it is only openshift, or does it happen to with k8s? | 08:01 |
livelace | Hello guys, I'm going to understand the PLEG problem at the weekend too | 08:03 |
livelace | Last time, when I enabled all debugs, the PLEG problem was gone and I couldn't reproduce it, it happens at the beginning of my deployments | 08:06 |
apuimedo | livelace: I'm struggling with it in a 26 node deployemnt | 08:07 |
apuimedo | *deployment | 08:07 |
apuimedo | 2-3 nodes start going notready then ready and others go notready | 08:07 |
livelace | After some time/some special fluctuations they may gone, but may stay | 08:07 |
*** oikiki has quit IRC | 08:07 | |
apuimedo | livelace: did you see cni timeouts in your kubelet logs? | 08:07 |
livelace | apuimedo, I'm not sure that it is cni timeouts, because PLEG appears without cni timeouts too | 08:08 |
livelace | I guess it happens during interface binding to the Neutron ports | 08:09 |
apuimedo | livelace: I always got the impression that docker runtime PLEG, once it sees some issues loses all trustworthiness | 08:09 |
apuimedo | xD | 08:09 |
livelace | During this time | 08:09 |
livelace | Folks from https://github.com/kubernetes/kubernetes/issues/45419 met the PLEG problem with another network solutions (weave,calico) too | 08:10 |
livelace | I think kubelet/origin-node donesn't like network switching timeouts, or other such things | 08:11 |

*** limao has joined #openstack-kuryr | 08:12 | |
apuimedo | livelace: I agree | 08:13 |
ltomasbo | so, do you have in mind any workaround until this is discovered/fixed? | 08:17 |

livelace | ltomasbo, If question was for me - I don't know, as I told - PLEG problem may be gone, need to find patterns of this behavior | 08:24 |

dmellado | awesome, I knew this was going to be broken | 08:36 |
dmellado | janonymous: could you paste your patch? | 08:37 |

dmellado | as I expected, it seems the migration to zuulv3 disn't go well | 08:45 |
dulek | dmellado: As everyone expected? ;) | 08:45 |
dmellado | let's see what that patch has to say after janonymous' trial patch xD | 08:46 |
dmellado | dulek: totally xD | 08:46 |
apuimedo | dmellado: it went well. I get very suspicious if upgrades don't break | 08:47 |
*** wangbo has joined #openstack-kuryr | 08:47 | |

dmellado | if you check my patch there, which just adds a 'foo' it seems that it's going so far | 09:34 |
dmellado | will wait for it to end | 09:34 |
