oansonI suspect this is a failure to connect to the OVS DB daemon.08:57
oansonCould you please verify that OVS DB server is up? Perhaps: ps aux | grep ovs08:57
*** hshan has joined #openstack-dragonflow08:57
hshanoanson, i'm back, do you see the fullstack log I sent just now08:58
oansonYes.08:58
oanson I suspect this is a failure to connect to the OVS DB daemon.08:58
oansonuld you please verify that OVS DB server is up? Perhaps: ps aux | grep ovs08:59
oansonCould*09:00
hshanyes, I think ovsdb server is up09:00
oansonOne sec. Let me connect to my environment.09:00
hshanI also think this problem is related with the db connection09:01
oansonYou see a line similar to: root     28802  0.0  0.1  46628  4924 ?        S<   Apr18   0:54 ovsdb-server /etc/openvswitch/conf.db -vconsole:emer -vsyslog:err -vfile:info --remote=punix:/var/run/openvswitch/db.sock --private-key=db:Open_vSwitch,SSL,private_key --certificate=db:Open_vSwitch,SSL,certificate --bootstrap-ca-cert=db:Open_vSwitch,SSL,ca_cert --no-chdir --log-file=/var/log/openvswitch/ovsdb-server.log --pidfile=/09:01
oansonvar/run/openvswitch/ovsdb-server.pid --detach --monitor ?09:01
oansonWhat about the output of: sudo netstat -t -l -p -n | grep 6640 (and then sudo netstat -t -l -p -n | grep ovsdb-server)?09:02
hshanI have a ovsdb-server running same with your's09:03
oansonAnd the netstat output?09:04
hshanno output, it seems 6640 is not listen09:04
oansonAnd if you grep for ovsdb-server?09:05
hshanboth netstat commands don't output09:06
oansonSo the ovsdb-server isn't listening at all.09:06
oansonI guess this could be resolved by restarting it: service openvswitch restart (fedora) or service openvswitch-switch restart (ubuntu)09:06
hshanbefore this problem, I got following error:09:07
hshanovs-vsctl: unix:/usr/local/var/run/openvswitch/db.sock: database connection failed (No such file or directory)09:07
oansonAny idea how this could have happened? Did you run two at the same time and close one?09:07
oansonHmm... What's the output of ovsdb-server --version ?09:07
hshanI have to change '/usr/local/var/run/openvswitch' to 'var/run/openvswitch'09:07
hshanovsdb-server (Open vSwitch) 2.5.109:08
hshanCompiled Apr  5 2016 15:30:4909:08
oansonIt should have the correct path by default, unless there was an error in installation.09:08
hshanit's pretty new09:08
oansonIt should be >= 2.5.90.09:08
hshanoh, I need to update to >= 2.5.90 ?09:09
oansondevstack installs it for you. It installs from git, so it should be bleeding edge.09:09
oansonWhen did you do devstack on this machine?09:10
hshanfeipeng make a devstack image a month ago, all of us use this image09:11
hshan*made09:11
oansonYou clone a VM image with devstack already running?09:11
oansonOr with openstack already running?09:12
hshanno, the image just contains all the package devstack needed, we still need to do stack.sh09:13
oansonThat's all right - stack should download the latest versions of dragonflow and ovs09:15
hshanokay, I'll do stack.sh again09:15
oansonI think that's the right thing to do.09:16
hshandoes idl rely on some new features of OVS?09:16
oansonYou may need to uninstall the old OVS first09:16
hshanok09:16
oansonI don't think so, but we rely on the bleeding edge for a few features. (I think e.g. connection tracking, IIRC)09:16
hshando you know which db.sock should be used ?  /usr/local/var/run/openvswitch/db.sock or /var/run/openvswitch/db.sock09:18
oansonThe second one. Both server and clients should use it automatically. (Except dragonflow, which currently connects via IP)09:18
hshanok, thx09:20
