redcavalierHi, I've been running into a neutron bug since upgrading to the latest Ocata in September and I've been trying to figure out the cause for a while now.01:18
redcavalierFirst I must say we use L3-high availability between 2 network-only nodes01:19

redcavalierRandomly, for no apparent reasons, when we create a floating ip, the floating ip and iptables rules are created in the namespace, but there's no port created in the namespace to link it to the instance01:21

redcavalierOut of curiosity, is it the l3 agent that creates a port for a vm in the namespace, or the openvswitch/linuxbridge agent?03:24

*** imfearless has joined #openstack03:37
SamYapleredcavalier: the port in the namespace with the l3-controller in the router namespace is for the router and thats iptables so, there is a little dance to get iptables rules applied03:38

redcavalierSamYaple, sorry, I might not have been clear. I'm talking on a network node in it's namespace. I'm running in an issue where and instance's interface inside the namespace is not created.03:57
*** AnilV4 has joined #openstack03:57
*** fragatina has joined #openstack03:57
*** fragatina has quit IRC03:58
*** fragatina has joined #openstack03:58
SamYapleredcavalier: there is no instance interface on the network node03:59
redcavalierSamYaple, you're right. I'm explaining this poorly04:00
*** shintaro has joined #openstack04:00
*** salv-orlando has quit IRC04:00
redcavalierSamYaple, so, when I add a floating ip to an instance, it doesn't show up in the list when I do ip netns *namespace* ip a. Its iptables rules are there though.04:01
*** catintheroof has joined #openstack04:01
SamYapleredcavalier: so the floating ip wont be a *new* interface, it will be a /32 on the routers interface04:02
SamYapleand you are saying thats not showing up?04:02
redcavalierexactly04:02
*** germs1 has quit IRC04:02
SamYaplelegacy router? (no dvr, no ha)?04:02
redcavalierthis happens randomly though. Like, it can work for a week, and then suddenly fail04:02
redcavalierHA04:02
SamYapleif its HA, are you sure its not in one of the other network namespaces? (it should onyl live in one)04:03
*** spzala has joined #openstack04:03
redcavalierSamYaple, all floating IPs should be in the same one. If it pops up in the inactive one, there'S still a problem.04:03
SamYapleoh you are saying some are still there?04:04
redcavalieryes, what happens is that we are able to set up floating ips for like 2 or 3 weeks and then, suddenly, new floating ips stop showing up in the namespace04:04
SamYapleso a few questions, when this happens you have other working floating ip address in that router-namespace? does detaching and reattaching the ip help?04:05
SamYaplefirst question answered04:05
redcavalierDespite iptables being set properly and openstack believing everything is alright04:05
redcavalierdetaching and reattaching does not help04:05
*** catintheroof has quit IRC04:05
redcavalierto have it work, we've had to reboot both network nodes04:06
SamYaplecertainly sounds like a bug. i would dig into the keepalived logs (assuming no errors in neutron-l3-agent logs)04:06
SamYaplesounds like a keepalived issue04:06
redcavalieralright. To be honest, it'S been happening since we updated Ocata at the end of september04:06
SamYaplein l3-ha i belive keepalived handles all of that04:06
SamYapleso when this happens next time, try killing all the keepalived processes and restarting the l3 agents04:07
redcavalierin what file are the keepalived logs located by default?04:07
redcavalierok04:07
*** spzala has quit IRC04:07
SamYaplehmmm good question04:07
*** woodard has quit IRC04:07
SamYaplei belive /var/log/neutron/*04:07
SamYaplebut im not sure they are logged by default04:07
SamYaplei dont use l3-ha and havent in a while04:08
redcavalierI don't remember seeing a keepalived log file04:08
SamYapleps aux | grep keepalived04:08
SamYaplethat might tell you where its logging04:08
SamYaplei cant remember if keepalived can log to a file directly, or requires syslog04:08
SamYapleif its syslog, then you should have that somewhere04:08
SamYapleredcavalier: when moving to ocata, did keepalived version change?04:09
redcavalierSamYaple, good question. let me check the yum logs04:09
*** jdwidari has quit IRC04:10
redcavalieralso, the process doesn'T indicate any logs04:10
SamYaplein anycase, if killing keepalived and restarting l3-agents (to regen keeplived process) fixes it, i think its safe to say keepalived is having issues04:10
SamYapleat that point you would just need to track down *why*04:10
*** rideh has quit IRC04:10
SamYaplebut all openstack can do is inform keepalived of the update, it assumes keepalived is oging to handle it form there04:11
redcavalierI see04:11
redcavalierdoesn'T openstack also generate the keepalived configuration?04:12
*** rideh has joined #openstack04:12
SamYapleyes, but i doubt the keepalived config is broken04:13
SamYapleits probably a nohup thats not working or something04:13
SamYapleyou can verify that now that you have a direction to look04:13
redcavalierok. and yes, there was indeed an update of keepalived04:13
SamYapleso its eitehr a new bug in keepalived, or a bug in neutron configuring the new keepalived04:13
*** davidbowlby-afk has quit IRC04:13
SamYaplepossibly it needs a new option or something04:14
SamYaplemore debuging and info is required04:14
*** vks1 has joined #openstack04:14
redcavalieryea, I'll see what I can find. Is it documented how to have keepalived log somewhere when its config is managed by openstack?04:15
*** ldl has joined #openstack04:15
ldlHi, friends, who can help me with this?04:15
ldlhttps://ask.openstack.org/en/question/110857/after-use-admin-change-the-normal-users-password-i-can-not-use-the-new-password-to-login/04:15
*** fragatina has quit IRC04:16
SamYapleredcavalier: its keepalived, so the config and cli is the only thing that its going to read. neutron might havea way to append args or something04:16
SamYapleredcavalier: but probably not documented well if it exists04:16
SamYaplethe core configuration would not be configurable given neutrons history04:16
SamYapleredcavalier: source code doesnt lie, if its an option, itll be in github.com/openstack/neutron/neutron/conf04:17
redcavalierSamYaple, so basically, if it'S not there, there's not much I can do beside coding it myself04:18
*** dparkes has quit IRC04:18
*** imfearless has quit IRC04:18
SamYapleredcavalier: lol lets identify the problem before we start talking about the limitations of neutron :P04:18
*** thorst has joined #openstack04:19
redcavalierhey, I'm just trying to give myself log to work from :p04:19
SamYapleyou probably dont need to change anything, its possibly a bug in neutron, its probably an issue with keepalived04:19
SamYapleredcavalier: you could always *downgrade* keepalived, run with that for a bit04:19
*** gkadam has joined #openstack04:19
SamYaplebut to get any type of resolution on this you need to be able to reproduce it and identify the cause04:20
*** dbecker has quit IRC04:20
SamYaplereproducing it should help with that04:20
redcavalierSamYaple, yea, I'll try to convince my boss with downgrading.04:20
SamYaple(wait for it to happen again and then try killing keepalived first)04:20
SamYaplefor all we know thats not going to fix it04:21

SamYapleGuest: no, the message is pretty clear and not openstack specfic at all. you cannot connect to port 5000 at 104.239.150.2904:44
SamYapleits because nothing is running there, or there is a firewall issue04:44
GuestSamYample: alright do you know how do we find our keystone auth url if we wanted to ?04:46
SamYapleGuest: figure out where keystone is running, at what ip and what port, then use that04:46

kevin_bthe rest i really cant share23:01
SamYaplemeh its all i need23:01
SamYapleok so, last question before advice23:01
SamYaplewhat version of openstack?23:01
kevin_bSadly Juno.. working on upgrades23:02
kevin_bbasically the same problem if someone restarts the agent, know that's fixed in newer revs, but this looks to be an ovs level issue23:02
SamYaplecool. so are you *sure* its a storm and not just alot of arp requests?23:02
kevin_btakes 5+ minutes to recover23:03
SamYapleyea. thats not a storm. thats just alot of requests23:03
SamYapleyou want to turn on l2_pop and arp_responder23:03
SamYapleshould resolve your issues23:03
kevin_bfor vlan based vm's ?23:04
kevin_bGRE based ones have always been fine in this config23:04
SamYapleoh i see. i read vxlan23:04
SamYaplehmmm. let me think23:04
kevin_bvm->ovs->vlan->bond0->world23:05
kevin_bif it helps23:05
kevin_bbond0 is lacp23:05
SamYapleyou definetely should have l2_pop and arp_responder onfor any tunnel networks. they were specifically written for ovs. but back to the issue23:05
kevin_bthanks for thinking on it. I ran out of ideas23:07
*** yamamoto has joined #openstack23:07
SamYapleok more questions23:07
SamYapledoes it act like this when you restart *any* node, or just the comptues? or just the controllers?23:08
*** smccarthy has quit IRC23:10
*** yamahata has quit IRC23:10
kevin_bif ovs is restarted on any host with a direct to vlan vm it impacts the whole network23:10
*** drbroiler has quit IRC23:10
SamYapleso the compute nodes23:11
kevin_byep23:11
SamYapleok... bababaaa23:11
SamYapledoes restarting neutron-openswitch-agent on the compute also cause the issue?23:11
kevin_byes, mostly because on juno though. supposedly fixed in newer versions23:12
SamYapleright because back then it regened all the rules23:12
SamYaplei rememebr that23:12
*** yamamoto has quit IRC23:12
SamYaplei suspect that might be the entirety of the issue here23:12
SamYaplei havent had ovs issues like that in a couple of years23:13
*** ginsul has quit IRC23:13
SamYaplemy best advice would be to migrate vms before you do maintenance on the computes23:13
*** ginsul has joined #openstack23:13
SamYaplebut thats my general advice anyway23:13
*** gnufied has quit IRC23:13
SamYaplekevin_b: you have the option of pulling in the 4.4 kernel in 14.04 which has newer better ovs if you think its an ovs issue23:14
kevin_bThat's another one i've been beating on... newer kernels. they are staying on 3.13 because it's "tested" :(23:14
SamYaplewell 4.4 is the lts kernel23:15
SamYapleits "tested" in the same way23:15
SamYapleand it has support until 14.04 EOLs23:15
kevin_bby tested i mean tested in our setup.23:15
kevin_b3.13 is also supported until 14.04 EOLS, so it's hard to convince them to change23:15
SamYaplei get your point23:15
SamYapleif you can do this on a test node, showing either diffeernt behaviour (it doesnt break everythign when a node reboots) or the same then youll have more info23:16
kevin_bso is it basically because the flow table is gone that the vlan's flood?23:16
kevin_byep i'll see if i can get that tested.23:16
SamYaplekevin_b: thats what my suspicion is, yes23:17
SamYaplei mean that is behaviour ive seen before23:17
*** ginsul has quit IRC23:17
kevin_bi see there's an option to the init script to keep flows may have to test that and see if it stops the mess at least on planned restarts23:17
kevin_bprobably not much we can do on reboots23:18
SamYaplekevin_b: you might try disabling neutron-openvswitch-agent and rebooting23:18
SamYapleif on reboot the "storm" doesnt happen, then you have your answer23:18
kevin_bi didn't think flow tables survived a reboot23:19
SamYapletis my point23:19
SamYapleif you suspect its an issue with OVS, this will prove/disprove that23:20
kevin_bahh23:20
kevin_bif we reboot and leave physical interfaces offline, let openvswitch-agent and ovs start, wait 15-20 minutes and bring the external interface up the problem doesn't happen23:21
kevin_bif that makes any sense23:21
SamYapleyoure really testing my memory here, but if i *recall* correctly, the issue was with the way it laid down the flow rules, it doesnt do it all atomically, so there are times when the flows are partitially there (even mometarily) which caused issues23:23
SamYaplefixed with drop all rules later23:23
kevin_bso without the drop all rules it's like having a dumb hub in there23:23
SamYapleagain, if my memory isnt letting me down yes23:24
kevin_bhmm maybe we can script something to force the drop all rules in before agent startup23:24
kevin_bhave to think on that one23:24
SamYaplenah its just going to clear the rule before it lays down its own23:25
*** penick has quit IRC23:25
SamYapleso youll end up in the same situation23:25
kevin_band when ovs is restarted but not the agent, the agent notices and wipes and restarts the same way23:26
kevin_bso restarting either makes for a mess23:26
kevin_bwhat i think we need to try is an ovs restart WITHOUT the agent running.23:27
SamYapleupgradingis the solution! :/23:27
*** thorst has joined #openstack23:27
kevin_byep painfully aware23:27
SamYapleyea possibly chanigng the orderingwill help you here23:27
kevin_bok thanks for the help. gave me some ideas to try next round of debugging23:27
SamYaplegood luck!23:28
kevin_bin the end it's because the agent isn't atomic. The next test on my list is disabling the agent, and just restarting ovs23:29
SamYaplei said dont quote me!23:29
SamYaple:)23:29
kevin_bit'll probably be fine without the agent making a mess23:29
SamYapleyou should be happy to know though that i havent had less issues in a long time. at least since liberty23:29
SamYaples/less/these23:29
kevin_bdont worry  i wont.. they'd probably have a cow if they knew i was asking on IRC ;)23:30
SamYaple"hey i talked the guys that wrote this software and they said...."23:30
SamYaplewhats wrong with that23:30
kevin_bheck i've been doing this since the days of diablo so....23:30
SamYaplenice! diablo was my first cluster23:30
SamYaplei still worked on an essex cluster until last year23:31
SamYaplei mean "worked" we would just tell them to upgrade23:31
kevin_bthat site until it was decommed was the most stable. It was just linux bridges to vlan :P23:31
SamYaplei happen to love OVS23:33
SamYapleeven with its issues23:33
SamYapledo not like linux bridge. even with its (mostly) lack of issues23:33
kevin_byeah, i'm still using linux bridges on my home stuff, but wonder if it is worth going to ovs23:33
SamYapleovs can do alot of realyl cool stuff that LB never ever will be able too23:33
SamYapleforbetter or worse ;)23:33
SamYapleis it "worth" it? probably not23:34
SamYapleis it "cool" and are there alot of cool things to play with? absolutely23:34
SamYaplefor your home cluster that is23:34
kevin_bmy first ovs experience was with a commercial app on top of ovs 1.x23:34
SamYapleim sorry for your loss23:34
kevin_bnicira23:34
kevin_bor something like that23:34
kevin_bbeen so long ago23:34
SamYapleoh im well aware. i was at rackspace when that happened23:34
kevin_byep Nicira23:35
SamYapleindeed.23:35
kevin_bthing could never scale so we moved on quick23:35
SamYaplewent to private cloud and had to use 1.10.2 (which is a dev release BTW) for a long time after23:35
SamYaplethen it had such a bad name that no one wanted to use it23:36
kevin_bmegaflows made a big difference way back then23:36
SamYaplebut i still love my ovs23:36
kevin_bWell thanks again. Gave me some ideas to take back to debugging.23:37
SamYaple+123:37
kevin_bi really want to find a solution that doesn't mean turning off interfaces to reboot :( and unplanned reboots are whole nother thing23:37
SamYaplekevin_b: might i suggest disabling neutron-*-agent again?23:38
SamYaplemanualyl starting it when youre ready23:38
SamYaplewould prevent thisissue unexpectedly happening23:38
*** thorst has quit IRC23:38
kevin_byeah i think that was the current plan.. a sleep in the agent startup or something goofy.23:39
SamYaplenow lets talk about rabbitmq clustering and galera issues!23:39
kevin_bbut what doesn't make sense is no flood if we start ovs+agent with interfaces down, but then bring them up. I'd think if it was the agent it would happen when the agent could finally connect out and get the network config..23:40
kevin_banyway.. sorry forthe babbling23:40
SamYaplewell that does make sense actually23:40
SamYapleif you are willing to lay the blame on neutron23:40
SamYaplebecause with the interfaces down you can safely lay downthe rules23:40
kevin_bWe have those too. Pretty much had to toss of ceilometer cause it was killing rabbit. It'll need its own rabbit cluster. and nasty deadlock in galera in active/active/active configs :(23:41
kevin_bthe base rules, but non of the info in neutron db?23:41
kevin_bnone23:42
SamYaplekevin_b: im 95% sureall the deadlockissues aresolved my mitaka23:42
SamYaplethere was 1 in nova and 1 in neutron in liberty23:42
SamYapletheremight stillbe one in neutron23:42
SamYaplebut for all other services active/active til your heart is content23:42
kevin_bwe have a race condition we are fighting in cinder too.. weeeee23:42
SamYapleand switch to rabbitmq autoclusterer23:42
SamYaplekevin_b: cinder-volume with shared backend?23:42
kevin_b3 api hosts for cinder, with haproxy round robin.. makes a mess23:43
kevin_bif someone does something stupid like submit a bunch of attaches in a row23:43
SamYaplewhats your cinder backend?23:44
kevin_bfor the same volume. That ends up being a manual database cleanup :(23:44
kevin_bsolidfire23:44
SamYapleah yea. lots of those issues are resolved by mitaka timeframe too23:44
kevin_byeah they chose to go to one api server managed in ha software, i said WTH didn't you just do active/passive/passive in haproxy23:45
*** cyborg-one has joined #openstack23:45
SamYapleyup thats the way you fix that :/23:46
kevin_banyway. So things make a lot more sense. Time to write and email while it's in my head. Need to get agent logs from a host started with interfaces down and see what gets layed down23:46
SamYaplegood luck again:)23:46
kevin_byep it's late here time to call it a night.23:47
kevin_bThanks a lot23:47
