On 4.6 ovs-vswitchd is managed by systemd. ovs-vswitchd is set to Restart=on-failure According to https://www.freedesktop.org/software/systemd/man/systemd.service.html#Restart= "on-failure" will not restart on clean exit code, so it won't restart on pkill it looks like the ovs-vswitchd.service is in RHCOS, so we need to modify it to be Restart="always" in RCHOS? And the fact that ovs-vswitched on 4.6+ is now a service unit so not a good idea to use Process kill (pkill) which also implies that ovs-vswitched should be used with systemctl now. That being said, we still need to investigate why flows lost on < 4.6 during post pkill This will still block verification though on 4.6 due to https://bugzilla.redhat.com/show_bug.cgi?id=1854801 *** This bug has been marked as a duplicate of bug 1852618 *** |
