Description Eran Kuris 2017-10-02 10:30:28 UTC

Description of problem:
on the latest puddle, I saw in logs those error after fresh install:

[root@controller-1 ~]# tail -f /var/log/openvswitch/ovsdb-server-nb.log

the error exists on OVN slave nodes.

How reproducible:
100%



Steps to Reproduce:
1. Deploy Director HA 12 with OVN
2.check the log under /var/log/openvswitch/ovsdb-server-nb.log

Actual results:
error logs

Expected results:
no errors 

Additional info:

Comment 1 Numan Siddique 2017-10-03 07:05:37 UTC

The reason for these error logs is:

 - In the case of OVN HA, ovsdb-server's are started in each controller as standby and then pacemaker promotes one as master on the node where VIP  (ip-XXXXX) resource is started (because of colocation constraints set).

On all the controller nodes, ovsdb-servers are started with the option "--remote=ptcp:6641:VIP. Since the VIP is not present in the stand by nodes, the ovsdb-servers log the error messages.

Presently this is as expected. But the error logs could be annoying and I think it can be taken care in ovsdb-server to not log these error messages. Or may be don't open the socket if it's a standby server.

I would say its a low priority issue.

Comment 2 Numan Siddique 2017-10-04 13:56:51 UTC

Submitted the patch in puppet-tripleo to set 'ip_nonlocal_bind' sysctl flag so that we don't see the error messages reported here.
