gsagie | from the agenda i guess they are not going to work on OVN in the mid-cycle sprint :| | 15:18 |
gsagie | or i got it wrong? | 15:19 |
russellb | gsagie: i don't think anyone who's working on OVN went | 15:19 |
gsagie | russellb : regarding your question in the mailing list, i will reply there but there are various DB's which support OVSDB features as far as i could see, for example: Redis, Cassandra, Aerospike, Voldemort (Some have publish/subscribe at a seperate project but still..) | 15:21 |
* russellb nods | 15:21 | |
russellb | just didn't know if you wanted to look at one in particular in some detail | 15:21 |
russellb | i was also thinking about etc | 15:21 |
russellb | err, etcd | 15:21 |
russellb | that seems hip these days :-p | 15:22 |
gsagie | etcd/zookeeper/consul.io and such are very good for consistency but i am not sure regarding the size of data | 15:22 |
russellb | i'm not sure either | 15:22 |
russellb | OVN data isn't large, at least | 15:22 |
russellb | small records, but lots of clients | 15:23 |
gsagie | yes | 15:23 |
gsagie | but they are certinly good options depending on the data size | 15:25 |
russellb | admin port state support got merged for OVN, so i'm doing the networking-ovn part now | 15:25 |
russellb | one test failure under control at least, heh | 15:25 |
gsagie | ok cool :) good job | 15:25 |
russellb | gsagie: ben merged my first approach, he didn't seem to care about trying to disable the port with openflow | 15:28 |
russellb | seems good enough for now so i'm just moving on | 15:28 |
gsagie | yeah i saw, doesnt matter from the networking-ovn side anyway | 15:28 |
gsagie | want me to do it? | 15:29 |
gsagie | nvm, i will only be able to take it on sunday | 15:29 |
russellb | networking-ovn side? nah, i'll get it done today. | 15:30 |
russellb | it's refreshing compared to digging through weird failures ... feels more productive :) | 15:30 |

russellb | s3wong: my devstack hangs on creating a network, as well | 19:05 |
russellb | don't know what's happening yet | 19:05 |
s3wong | russellb: Oh good, so not just me then :-) | 19:08 |
openstackgerrit | Russell Bryant proposed openstack/networking-ovn: Add support for port admin_state_up https://review.openstack.org/195703 | 19:08 |
russellb | s3wong: yeah :) | 19:08 |
russellb | s3wong: weird that it doesn't happen in CI | 19:08 |
russellb | s3wong: did you try Ubuntu? | 19:08 |
s3wong | russellb: Neutron default works, so it seems to be related to OVN for sure | 19:08 |
russellb | right | 19:09 |
russellb | i'm using Fedora 22 | 19:09 |
russellb | but CI uses Ubuntu | 19:09 |
s3wong | russellb: yes, the first OS I tried was Ubuntu 14.04 | 19:09 |
russellb | s3wong: OK thanks | 19:10 |
s3wong | russellb: to give a more proper timeline, it started happening for me since weekend | 19:12 |

* russellb tries to find the right thing to install | 19:15 | |
russellb | ah, the python debuginfo package i think. | 19:17 |

*** arosen has joined #openstack-neutron-ovn | 19:59 | |
russellb | otherwiseguy: o/ | 20:24 |
russellb | otherwiseguy: i'm having a fun ovsdb related issue ... in short, when you run devstack with OVN, neutron-server hangs when you try to create a network (devstack itself hangs when it tries to do initial network setup) | 20:25 |
russellb | i've traced it down to: neutron.agent.ovsdb.impl_idl.Transaction.commit() where it calls self.results.get() | 20:25 |
russellb | that's where it gets stuck | 20:26 |
russellb | any ideas? | 20:26 |
russellb | arosen: i guess you're not seeing this on your dev system? | 20:32 |
russellb | someone else, s3wong, said he got this consistently on several different systems (ubuntu, fedora, aws linux) | 20:32 |
russellb | and it happens on my f22 devstack i spun up today | 20:32 |
russellb | ... well, i reverted neutron back to pre-vancouver, which i know worked, and i still see it, so it's something else | 20:41 |
arosen | you need to set API_WORKERS=0 in local.conf | 20:41 |
russellb | what changed? devstack? | 20:41 |
arosen | there is a patch on review that fixes this but it hasn't merged yet. | 20:41 |
arosen | Maybe you only have one processor in your vm so it defaults to 1 for you? | 20:42 |
arosen | i'm not sure. | 20:42 |
russellb | 4 vCPU VM | 20:42 |
arosen | or if you apply: https://review.openstack.org/#/c/192279/ | 20:42 |
arosen | it could be a weird race I'm not sure to be honest. | 20:42 |
arosen | It's a problem how neutron-server forks off multiple api workers before we connect to ovsdb i beleive. | 20:42 |
russellb | ok, i'll try API_WORKERS=0 | 20:43 |
russellb | my favorite thing ever is how long stack.sh takes to run | 20:45 |
arosen | :) | 20:46 |
otherwiseguy | russellb: yeah, api_workers needs to be zero for now. I've got some patches that fix it. Doing the last iteration (hopefully) on them today/tomorrow. | 20:55 |
otherwiseguy | russellb: it's still *way* faster than packstack. :) | 20:56 |
otherwiseguy | (devstack, that is) | 20:56 |
russellb | argh, sure enough that did it | 21:15 |
arosen | yay :) | 21:16 |
russellb | i knew about otherwiseguy's patches, but i didn't connect this issue with that | 21:16 |
russellb | but yay for it being known | 21:16 |
otherwiseguy | It is known. | 21:16 |
