[Kolla Ansible] host maintenance
by Tony Liu 25 Aug '20

25 Aug '20

Hi, I wonder if it's supported by Kolla Ansible to deploy a specific host and add it into existing cluster, like replace a control host or compute host? Thanks! Tony

Cliff auto completion not working inside interactive mode
by sandeep 25 Aug '20

25 Aug '20

Hi Team, In my system, I am trying auto completion for my CLI application. *CLIFF version - cliff==3.4.0* Auto complete works fine on bash prompt. But inside the interactive shell, auto complete does not work. Below is the screenshot for the help command inside the interactive shell. [image: image.png] Now, if I type swm and press tab, it lists all the sub commands under it. But, swm s<tab> gives swm "s and further command auto completion does not work. [image: image.png] Could you please let me know what could be the problem? Is this a known issue? or Am i missing something? Thanks, Sandeep

by Fabian Zimmermann 25 Aug '20

25 Aug '20

Hi, im currently on the way to analyse some rabbitmq-issues. atm im taking a look on "unroutable messages", so I * created an Alternative Exchange and Queue: "unroutable" * created a policy to send all unroutable msgs to this exchange/queue. * wrote a script to show me the msgs placed here.. currently I get Seems like my neutron is placing msgs in these exchanges, but there is nobody listening/binding to: -- 20 Exchange: q-agent-notifier-network-delete_fanout, RoutingKey: 226 Exchange: q-agent-notifier-port-delete_fanout, RoutingKey: 88 Exchange: q-agent-notifier-port-update_fanout, RoutingKey: 388 Exchange: q-agent-notifier-security_group-update_fanout, RoutingKey: -- Is someone able to give me a hint where to look at / how to debug this?

[nova][neutron][oslo][ops] rabbit bindings issue
by Arnaud Morin 24 Aug '20

24 Aug '20

Hey all, I would like to ask the community about a rabbit issue we have from time to time. In our current architecture, we have a cluster of rabbits (3 nodes) for all our OpenStack services (mostly nova and neutron). When one node of this cluster is down, the cluster continue working (we use pause_minority strategy). But, sometimes, the third server is not able to recover automatically and need a manual intervention. After this intervention, we restart the rabbitmq-server process, which is then able to join the cluster back. At this time, the cluster looks ok, everything is fine. BUT, nothing works. Neutron and nova agents are not able to report back to servers. They appear dead. Servers seems not being able to consume messages. The exchanges, queues, bindings seems good in rabbit. What we see is that removing bindings (using rabbitmqadmin delete binding or the web interface) and recreate them again (using the same routing key) brings the service back up and running. Doing this for all queues is really painful. Our next plan is to automate it, but is there anyone in the community already saw this kind of issues? Our bug looks like the one described in [1]. Someone recommands to create an Alternate Exchange. Is there anyone already tried that? FYI, we are running rabbit 3.8.2 (with OpenStack Stein). We had the same kind of issues using older version of rabbit. Thanks for your help. [1] https://groups.google.com/forum/#!newtopic/rabbitmq-users/rabbitmq-users/zF… -- Arnaud Morin

[ovn][neutron][ussuri] DPDK support on OVN Openstack? Openstack Doc contradictive Information?
by Popoi Zen 24 Aug '20

24 Aug '20

I want to implement DPDK on my Openstack using OVN as mechanism driver. I read 2 documentation: [1] https://docs.openstack.org/neutron/ussuri/admin/ovn/dpdk.html [2] https://docs.openstack.org/neutron/ussuri/admin/config-ovs-dpdk.html In first doc [1], it is said that DPDK has been supported on OVN. But in second doc [2] it is said `The support of this feature is not yet present in ML2 OVN and ODL mechanism drivers.` Which one is true? because I have TCP checksum issue when implement DPDK on OVN same like this: https://bugs.launchpad.net/neutron/+bug/1832021. It has patched on OVS but not work on OVN. Regards,
