Re: [openstack-dev] [Neutron] Mitaka-2
Hello everyone, I would like to add to that list this [1] and this [2] bug. In my opinion they should be fixed ASAP and upstreamed. Currently I'm working on that and I received feedback from L3 subteam and Assaf about implementation and proposed solutions.

Re: [openstack-dev] [Neutron] L3-HA - Solution for GW not pingable issue bug/1365461
From the performance perspective it will require additional CPU time because of the need to run that bash script. I will try to prepare it as simple as possible but probability that it will kill server when there will be spawned huge amount of routers is not so big - after the implementation we can test CPU utilization with this validation enabled.

I think that first solution looks more solid, my concern here is how does this will affect the performance?

I tooked his code and was trying to upgrade that code to support multiple scripts but I was designed separate solution for that. I would like to know what do you think about this solution. 1. Add bash script generator to neutron/agent/linux/keepalived.py 2. There will be one script per one keepalived instance per node 3. There are two possible solutions for checking is everything is working OK. Script will verify: a. That all interfaces are up - internal router interfaces in namespace, external interface taken from neutron configuration file and also br-tun/br-int interfaces. b. That GW is pingable from router NS - there is only one problem what if GW is not configured in router already - plus we could ping other network node or other server which IP is specified in some configuration. That solution will also fix this issue [2]. I would hear from you what do you think about that two possible solutions and what do you think about whole solution at all.

[openstack-dev] [infra] Blocked access to Gerrit account.
Hello everyone, Yesterday I merged my two accounts on launchpad and after that I cannot log in to my account using SSO on OpenStack gerrit. When I'm logging using my merged account I'm landing in a new account, without any reviews, commits and anything else. Additionally right now there are two available options in owner filter. When you specify lubosz.kosnik you will see two times the same option "Lubosz Kosnik <lubosz.kos...@intel.com" but that are two separate accounts. Is it possible to merge that two accounts into one or update SSO tokens to my old account? Thank you very much for any help. --- Lubosz (diltram) Kośnik __ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
Re: [openstack-dev] [neutron][L3] Wrong fail over of HA-Router
Here you have an information about that bug - it's a known issue in Keepalived v.1.2.7 https://bugs.launchpad.net/neutron/+bug/1497272 Regards, Lubosz On 01/14/2016 02:27 AM, Ikuo Kumagai wrote: Hi All Could you give me some advice for our problem? We use Neutron L3-HA. When I associate/disassociate floating-ip, the state of ha keepalived become MASTER/MASTER state. Then Because at that time,the sending of vrrp packet from MASTER to BACKUP stop for 40 seconds. I checked logs of Keepalived, there is the 40 seconds delay of between Log ( Initializing ipvs 2.6) and Log (Opening file ~). ex is below. -- Jan 14 09:51:22 stg-anlk-ctrl003 Keepalived_vrrp[1989701]: Initializing ipvs 2.6 Jan 14 09:52:02 stg-anlk-ctrl003 Keepalived_vrrp[1989701]: Opening file '/var/lib/neutron/ha_confs/666d9e40-a95c-44a1-a876-bf44ca281f3e/keepalived.conf'. -- During this time, the packet of vrrp for MASTER to BACKUP,so BACKUP changes to MASTER, and then original MASTER starts sendding vrrp packets again.
