lifelessmestery: around? or anyone really - the commit e5cdad90f97d3a54a493eca19e7a3ff643426de1 breaks gre tunnel synchronisation for tripleo deploys02:55
lifelessjamespd: hi!02:55
lifelesswe haven't tracked it all the way down, but the symptoms are very clear02:55
lifelessit appears the agent just doesn't get tunnel updates anymore02:55
lifelessI'm *guessing* its something to do with the use of the integration bridge mac as the tunnel endpoint, but *haaaandwave*02:56

lifelessWe've put a patch in place to revert that in the images we build so that our checks can run again02:58
lifelessbut, we'd like to revert it in neutron - you can check whatever re-attempt is used via 'check experimental' to get tripleo jobs run on it02:58
lifelessjamespd: any thoughts?03:00
jamespdsorry, that is a bit out of my wheel-house.03:00
jamespdI was hoping for something a little less gre/trippleo, which I pretty much know nothing about.03:00

lifelessah03:00
lifelessso it'll hit vxlan too AFAICT03:00
lifelessits really about the ovs agent03:00

mesterylifeless: Looking at the revert commit now.03:03
lifelessmestery: thanks03:03
mesterylifeless: I'm not sure why that would cause those issues, but I'm happy to approve the revert now until we figure out why.03:03
lifelessmestery: we've got full debug logs referenced from the bugs03:03
lifelesserm bug03:03
lifelessmestery: they'll stay around for whatever time infra keeps them ? 30 days?03:04
lifelessmestery: thank you!03:04
lifelessmestery: the thing that stood out to me is that the rpc agent setup depends on the br-int *state*03:04
lifelessmestery: and the rpc agent setup is moved *after* br-int configuration03:04
mesterylifeless: Yes, that seems like an oversight.03:04

lifelessmestery: whereas before it was before. Nothing *obviously* harmful in there, but its the only theory we have.03:05
* mestery nods in approval.03:05
lifelessmestery: we had a failure rate of 95+% and reverting this patch did 3 passes in a row03:05
lifelessso we're pretty confident03:05
mesteryYikes! Sorry about that lifeless.03:06
lifelessmestery: not your fault - our jobs are still in experimental, due to lots of reasons03:06
mesteryI've had travel issues today (cancelled flights), now leaving current location very early tomorrow.03:06
lifelessmestery: but anytime you want to know multi-node and/or tripleo status, run 'check experimental'03:06
lifelessand you'll get some multi-node gre testing03:06
mesterylifeless: Good to know03:06

salv-orlandorevert the revert commit09:42
salv-orlandoit has been done before09:42

salv-orlandokevinbenton: anyway restoring that patch is not super urgent, so I would wait for your other fix to go in (101447) and then let the other merge.09:54
kevinbentonsalv-orlando: i suppose that would work too. was just being lazy to avoid the conflic resolution09:55
salv-orlandothat’s ok. I was more worried about tripleO gate freaking out09:56
*** xuhanp has quit IRC09:56
salv-orlando tripleO team says their gate is quite without that patch, so that’s why I reverted even if I could hardly understand the reason. It’s a simple patch that can be restored at any time, as you’ve done now.09:56
*** devvesa_ has left #openstack-neutron09:59

*** devvesa_ has joined #openstack-neutron10:00
*** dguitarbite has joined #openstack-neutron10:00
kevinbentonsalv-orlando: the problem is that if i put my fix in first, then the revert will have conflict resolution as well10:00
salv-orlandonope, I will review 101447 and put 101463 in wip until 101447 is merged?10:00
salv-orlandokevinbenton: come on, conflict resolution there will be trivial ;)10:01
kevinbentonsalv-orlando: well 101447 is dependent on 101463, so you will be waiting a long time :-)10:01
kevinbentonsalv-orlando: that’s what I meant about reversing the order. my fix now conflicts with the state of master so i reverted the revert and made my fix dependent on that10:03

ihrachyshkabut... I may not get how those implicit yields work in SQL library12:56
rkukuraihrachyshka: I’m not positive, but have been led to believe that the current sqlachemy backends do not do this implicit yielding. I think that is the root cause of the transaction deadlocks12:56

*** dguitarbite has joined #openstack-neutron12:58

*** zmielna has joined #openstack-neutron13:00
rkukuraihrachyshka: If the sqlalchemy backend does not implicitly yield while waiting for a response, and that response is waiting for a row lock to be released, and some other green thread has the row locked, sqlalchemy not implicitly yielding causes deadlock because the other green thread with the row locked cannot make progress and release the lock.13:00

*** zmielna has left #openstack-neutron13:01

*** vivek-ebay has joined #openstack-neutron13:02
rkukuraIf it could switch threads, the thread with the row locked would eventually release the lock.13:02
ihrachyshkarkukura: well... I consider those extra locks as quick hacks. Yes, they fix some unknown issues by serialising some suspicious transaction, but that doesn't solve the problem globally13:02
enikanorov_locks around transactions look ugly to me... although it helps sometimes13:02

zzellerkukura, kyle proposes you look at https://review.openstack.org/99356 which proposes the reuse mechanism in the dhcp agent, if you could give your feedback ?21:23
rkukurazzelle: I have not had time to look at this.21:24
zzellerkukura, no problem21:24
rkukuraI’ll try to, but don’t want to make promises I can’t keep.21:25
zzellerkukura, if u have time could you also look at https://review.openstack.org/99356 which is quite the same proposal for l3 agent ... but i have the feeling the proposal design is not an improvement ...21:25
rkukurazzelle: I’m not seeing how I’m going to have time for anything before mid July :(21:26
zzellerkukura, outch, seems like a long todolist :s21:27
zzellerkukura, one final (small !) question about type_vlan/flat ...21:28
rkukurazzelle: small questions are good21:28
lifelesskevinbenton: pong21:28
zzelleyou had the TODO: Validate that each physical_network name is neither empty nor too long.21:29
openstackgerritDoug Wiegley proposed a change to openstack/neutron: LBaaS new object model logging no-op driver  https://review.openstack.org/10108421:29
zzellerkukura, am i wrong how such check must done on the OVS/modular L2 agent instead of the ML2 plugin ?21:29
zzelles/how/or/21:29
kevinbentonlifeless: trying to verify the updated fix for the neutron patch21:30
kevinbentonlifeless: now i just get this in the ovs agent log… http://logs.openstack.org/47/101447/3/experimental-tripleo/check-tripleo-overcloud-precise/a0f4649/logs/overcloud-NovaCompute0-veoyg6zjvdbv_logs/neutron-openvswitch-agent.txt.gz21:30
zzellerkukura, indeed type driver only uses physnet aliases21:30
*** lukego has quit IRC21:32
kevinbentonlifeless: and i’m not sure what would cause that21:33
rkukurazzelle: I think this TODO was to make sure the name fit in: physical_network = sa.Column(sa.String(64), nullable=False, primary_key=True)21:33
zzellerkukura, ok21:33
rkukurazzelle: That’s a server-side check. I don’t think the agent would care about the lenght of the names, but maybe about the names of the bridges they map to.21:33
*** suresh12 has joined #openstack-neutron21:34
*** padkrish_ has quit IRC21:34
*** padkrish has joined #openstack-neutron21:35
zzellecurrently it seems there is no bridge name length check ... i was about to add it when i see your comment ... so i check the TODO is not linked21:35
*** dvorkinista has quit IRC21:36
rkukurazzelle: Checking the length of the bridge name in the agent makes sense.21:36
lifelesskevinbenton: looks like a config issue; the tarball for the node has /etc in it21:36
*** dvorkinista has joined #openstack-neutron21:37
kevinbentonlifeless: ok. I’m in a meeting atm so I just launched another check. If it fails again with the same error I will look into it21:37
zzellerkukura, we already add (newbie) troubles ... if OVS bridge names are too long, the trouble is difficult to identify21:38

kevinbentonzzelle: I think I had brought up on a previous version detecting patch port capabilities rather than making it configurable22:39
*** sbalukoff has quit IRC22:39
kevinbentonzzelle: is that too painful to do in this patch?22:39
kevinbentonzzelle: maybe a follow-up patch...22:39
*** morganfainberg is now known as morganfainberg_Z22:41
zzellekevinbenton, in previous patchsets the capability was checked during startup ...22:42
zzellekevinbenton, but https://review.openstack.org/96525 removed runtime checks for vxlan and after discussion with kyle, it seems better to prefer static config22:42
zzellekevinbenton, moreover most deployments now support patch ports22:43
*** jecarey has joined #openstack-neutron22:43
zzelle(default config)22:43
kevinbentonzzelle: well the vxlan one makes sense because that’s big behavior change22:45
*** VijayB_ has joined #openstack-neutron22:45
kevinbentonzzelle: but this doesn’t really change the end result with regards to connectivity22:45
kevinbentonzzelle: it’s just an optimization, right?22:45
zzellekevinbenton, indeed22:46
kevinbentonzzelle: i wouldn’t worry about it in this patch though if Kyle was leaning away from detection22:46
zzellekevinbenton, it increases network performance on "old" kernels and reduces sudo latency !22:46
kevinbentonzzelle: right, it sounds like there is no reason someone would disable it if their kernel supports it22:47
kevinbentonzzelle: and no reason they would enable it if their kernel doesn’t22:47
zzellekevinbenton, if kernel does not support patch ports you change multiple default values22:47
zzellekevinbenton, initially the improvement was removing veth mtu22:48
