Description Miguel Angel Ajo 2019-02-05 22:09:08 UTC

Description of problem:

We see this on the ovs-vswitchd.logs of the hosts:

can be fixed by:

sudo ovs-vsctl set-fail-mode br-ex standalone
sudo ovs-vsctl del-controller br-ex

also all other bridge mapped bridges, this loop here looks like a good place to do it:

Can't verify before getting the fix of https://bugzilla.redhat.com/show_bug.cgi?id=1700302

Comment 16 Eran Kuris 2019-10-30 09:04:22 UTC

cant verify- depends on https://bugzilla.redhat.com/show_bug.cgi?id=1694572

Comment 19 Jakub Libosvar 2019-11-26 13:38:38 UTC

Closing as bug 1694572 won't make it to OSP14 before EOL.
