Region CentralRegion is not a valid region name for cloud envvars. Valid choices are RegionOne. Please note that region names are case sensitive. 13:36:49 oh, that's an old issue 13:37:06 you need to unset the environment variables 13:37:09 just run "unset OS_REGION_NAME" 13:37:10 neutron --os-region-name=RegionOne net-create net1, it works 13:37:35 yes 13:37:53 it tried 13:38:03 InternalServerError: Request Failed: internal server error while processing your request. 13:38:40 File "/usr/local/lib/python2.7/dist-packages/neutronclient/v2_0/client.py", line 365, in post 13:38:59 have you added the pod? and all pods exists 13:39:09 yes, all the pods are added 13:39:34 one region or two region 13:39:49 two region 13:40:32 then need to dig into the log file to see why 13:40:39 did the second region register to the keystone 13:41:10 Hello, joe. Sorry for lating, i am recently writing a paper for a conference in order to graduate, the conference dead time is near. i will give the completed code to jiawei for testing and upload it. 13:41:34 to xiongqiu, how about the spec? 13:41:55 i will finish the spec 13:42:07 to joehuang, yes 13:42:35 i will check logs to find the error 13:42:46 so openstack --os-region-name=RegionOne endpoint list works? 13:42:52 yes, please. 13:43:01 Other topics? 13:43:18 to joehuang, it works 13:43:26 also 13:44:08 if i create a net successfully, will neutron create corresponding ports? 13:44:17 no 13:44:26 ok, i see 13:44:47 only if you boot a VM in Nova, or explicitly create a port 13:45:25 how about dhcp_port? 13:45:42 will it also created when booting a VM? 13:45:47 dhcp port is created when you create the subnet 13:45:57 not network 13:46:11 no, i create a subnet, but there is no dhcp_port 13:46:17 and if enable_dhcp is true when creating subnet 13:46:42 you mean no dhcp port in local neutron? 13:47:18 yes, at first, i tried to install tricircle and octavia together with devstack 13:47:59 octavia will create a subnet, but it fails since there is no dhcp_port 13:48:19 i tried to install octavia manually 13:48:34 after create a subnet, still no dhcp_port 13:48:40 octavia will send command to regionone, I think. Unless you install ocatavia in central region 13:49:41 need to figure out which region ocatavia belongs to, and where the request it issued to 13:49:57 i see 13:50:42 by default, only tricircle api/xjob and central neutron server in central region in devstack installation 13:50:56 so ocatavia by default will be installed in regionone 13:51:31 yes, if lb talks to local neutron, it can create the subnet, but dhcp agent will fail to create the dhcp port because the ip is not allocated in central neutron 13:51:52 oh, i see 13:53:01 yes, the local neutron has been configured with tricircle local plugin, the dhcp port behavior is different the default 13:53:43 so i will check logs and try to create nets and subnets first, then install octavia manually. And go on testing 13:53:55 ok, to ronghui, look forward to the spec of qos 13:54:11 i think you can just configure LB to talk to central neutron 13:54:32 OR we need LB to talk to local neutron? 13:54:33 you can register ocatavia in central region, manually register 13:54:49 remove the old endpoint which resides in the regionone 13:55:38 yes, zhiyuan's proposal may also work 13:55:55 need to find the neutron url configuration in ocatavia 13:56:12 and change it, reboot ocatvia service 13:56:40 but one second 13:56:52 I am afraid it'll fail 13:57:09 because ocatavia now will boot LB service via Nova 13:58:11 I am not sure whether ocatavia can work with different region services, nova/glance in regionone, neutron in centralregion 13:58:22 if LB does need to talk to local neutron, then we need to create the network and subnet in central neutron first 13:59:08 I suggest Yipei to study that in detail 13:59:19 time is up 13:59:25 ok 13:59:28 and pass the subnet ID in central neutron to LB, when LB tries to query the subnet, the subnet will be created in local plugin 13:59:37 thank you for attending the meeting 13:59:57 #endmeeting
