[ovirt-users] OVS error logs after upgrade to 4.2
Hi, After upgrade to 4.2 I started getting this error from engine: /etc/cron.daily/logrotate: 2017-12-25T23:12:02Z|1|unixctl|WARN|failed to connect to /var/run/openvswitch/ovnnb_db.19883.ctl ovs-appctl: cannot connect to "/var/run/openvswitch/ovnnb_db.19883.ctl" (No such file or directory) 2017-12-25T23:12:02Z|1|unixctl|WARN|failed to connect to /var/run/openvswitch/ovnsb_db.19891.ctl ovs-appctl: cannot connect to "/var/run/openvswitch/ovnsb_db.19891.ctl" (No such file or directory) Seems harmless as i don't use OVS, but how to fix it?

By default, ovirt-4.2 installs and configure OVN (which uses OVS). You can turn it off on Engine host by running systemctl stop ovirt-provider-ovn ovn-northd openvswitch but I'd appreciate your help to understand in which log file do you see these warnings? Have you already disabled openvswitch? ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
Re: [ovirt-users] OVS error logs after upgrade to 4.2
Hi, It's not on log file, it's from automatic email sent by cron daemon. This one from logrotate. I'd like to migrate my network to OVS, but as i can't find any guide for that, it's a bit scary.

Re: [ovirt-users] OVS error logs after upgrade to 4.2
Hello Misak, This error hints that your ovn databases are not up (or at least can not be connected to). Could you please check if the following command gives any output: ps -ef|grep 'ovnsb_db\|ovnnb_db' The databases can be started (if not active) using: /usr/share/openvswitch/scripts/ovn-ctl start_ovsdb Could you please also check the content of: /var/run/openvswitch/ The filenames don't look normal (usually they do not contain any numbers as part of them), please give me some time to check this.

Re: [ovirt-users] OVS error logs after upgrade to 4.2
Hello Misak, Could you please file a bug about those error messages that you receive from OVS? You can use the log collector tool (https://www.ovirt.org/ documentation/admin-guide/chap-Utilities/#the-log-collector-tool) which gathers all the required logs for us to investigate this issue. Thanks for reporting this issue!

Re: [ovirt-users] OVS error logs after upgrade to 4.2
Hello Misak, The openvswitch team tells me this is a known ovs problem. It is fixed by patch: https://github.com/openvswitch/ovs/commit/bbf219ef584a102fde5150defab3a769a6a44981 merged in master/branch 2.8/branch 2.7. Looking at git history this is not yet released. It should be included in 2.7.4 when it's out.
