You're right, now that I look again. I missed the differences between the connections. > $ grep -r rconn ovs-vswitchd.log | grep 6653 > 2016-04-22T08:48:52.725Z|00022|rconn|INFO|s2<->tcp:127.0.0.1:6653: > connecting... > 2016-04-22T08:48:52.726Z|00023|rconn|WARN|s2<->tcp:127.0.0.1:6653: connection > failed (Connection refused) > 2016-04-22T08:48:52.726Z|00024|rconn|INFO|s2<->tcp:127.0.0.1:6653: waiting 1 > seconds before reconnect > 2016-04-22T08:48:52.726Z|00029|rconn|INFO|s1<->tcp:127.0.0.1:6653: > connecting... > 2016-04-22T08:48:52.726Z|00030|rconn|WARN|s1<->tcp:127.0.0.1:6653: connection > failed (Connection refused) > 2016-04-22T08:48:52.726Z|00031|rconn|INFO|s1<->tcp:127.0.0.1:6653: waiting 1 > seconds before reconnect > 2016-04-22T08:48:52.811Z|00032|rconn|WARN|s2<->tcp:127.0.0.1:6653: connection > failed (Connection refused) > 2016-04-22T08:48:52.811Z|00033|rconn|WARN|s1<->tcp:127.0.0.1:6653: connection > failed (Connection refused) > 2016-04-22T08:48:53.317Z|00070|rconn|INFO|s1<->tcp:10.25.2.14:6653: > connecting... > 2016-04-22T08:48:53.330Z|00075|rconn|INFO|s1<->tcp:10.25.2.14:6653: connected > 2016-04-22T08:48:53.449Z|00085|rconn|INFO|s2<->tcp:10.25.2.13:6653: > connecting... > 2016-04-22T08:48:53.459Z|00090|rconn|INFO|s2<->tcp:10.25.2.13:6653: connected > 2016-04-22T08:48:56.690Z|00184|rconn|INFO|s1<->tcp:10.25.2.12:6653: > connecting... > 2016-04-22T08:48:56.706Z|00189|rconn|INFO|s1<->tcp:10.25.2.12:6653: connected > 2016-04-22T08:48:56.854Z|00199|rconn|INFO|s1<->tcp:10.25.2.13:6653: > connecting... > 2016-04-22T08:48:56.865Z|00204|rconn|INFO|s1<->tcp:10.25.2.13:6653: connected > 2016-04-22T08:48:57.039Z|00214|rconn|INFO|s2<->tcp:10.25.2.12:6653: > connecting... > 2016-04-22T08:48:57.049Z|00219|rconn|INFO|s2<->tcp:10.25.2.12:6653: connected > 2016-04-22T08:48:57.184Z|00229|rconn|INFO|s2<->tcp:10.25.2.14:6653: > connecting... > 2016-04-22T08:48:57.199Z|00234|rconn|INFO|s2<->tcp:10.25.2.14:6653: connected > > There is only 6x "connected", so i believe that was no reconnection. 2 > bridges with 3 controllers each. > 1) Around time 08:48:53 14 became master s1 and 13 for s2 > 2) After time 08:48:56 i setup 2 more controllers for both s1 (12,13) and > s2(12,14). > > How do i know if i see "vconn|DBG|tcp:10.25.2.14:6653: received: > OFPT_ROLE_REQUEST (OF1.3) " if it is a request towards s1 or s2? You can't tell. This hasn't been an issue for me before, so probably, as one outcome here, we should improve the logging. I can think of two different ways to hunt down what you're seeing. One way would be for you to explain to me some simple way to reproduce it. If I can have that, I'm willing to spend some time trying to find or explain the problem. The other way would be to suggest some places that you can add additional logging to OVS, which would help to explain what is going on. That will probably take more back-and-forth and trial and error, but it wouldn't require that I be able to reproduce the problem here. What's your preference? _______________________________________________ discuss mailing list discuss@openvswitch.org http://openvswitch.org/mailman/listinfo/discuss
