Maybe restarting ovn-controller creates more helpful log messages? You can also try restart the ovn configuration on all hosts by executing vdsm-tool ovn-config OVIRT_ENGINE_IP LOCAL_OVIRTMGMT_IP on each host, this would trigger https://github.com/oVirt/ovirt-provider-ovn/blob/master/driver/scripts/se... internally. > So I would expect to see the same output for node01 to have a geneve > tunnel to node02 and vice versa. > > Me too. > On Fri, Sep 11, 2020 at 12:14 PM Dominik Holler <dholler(a)redhat.com&gt; > wrote: > >> >> >> On Fri, Sep 11, 2020 at 10:53 AM Konstantinos Betsis <k.betsis(a)gmail.com&gt; >> wrote: >> >>> Hi Dominik >>> >>> OVN is selected as the default network provider on the clusters and the >>> hosts. >>> >>> >> sounds good. >> This configuration is required already during the host is added to oVirt >> Engine, because OVN is configured during this step. >> >> >>> The "ovn-sbctl show" works on the ovirt engine and shows only two >>> hosts, 1 per DC. >>> >>> Chassis "c4b23834-aec7-4bf8-8be7-aa94a50a6144" >>> hostname: "dc01-node02" >>> Encap geneve >>> ip: "X.X.X.X" >>> options: {csum="true"} >>> Chassis "be3abcc9-7358-4040-a37b-8d8a782f239c" >>> hostname: "dc02-node1" >>> Encap geneve >>> ip: "A.A.A.A" >>> options: {csum="true"} >>> >>> >>> The new node is not listed (dc01-node1). >>> >>> When executed on the nodes the same command (ovn-sbctl show) times-out >>> on all nodes..... >>> >>> The output of the /var/log/openvswitch/ovn-conntroller.log lists on all >>> logs >>> >>> 2020-09-11T08:46:55.197Z|07361|stream_ssl|WARN|SSL_connect: unexpected >>> SSL connection close >>> >>> >>> >> Can you please compare the output of >> >> ovs-vsctl --no-wait get open . external-ids:ovn-remote >> ovs-vsctl --no-wait get open . external-ids:ovn-encap-type >> ovs-vsctl --no-wait get open . external-ids:ovn-encap-ip >> >> of the working hosts, e.g. dc01-node02, and the failing host dc01-node1? >> This should point us the relevant difference in the configuration. >> >> Please include ovirt-users list in your replay, to share the knowledge >> and experience with the community. >> >> >> >>> Thank you >>> Best regards >>> Konstantinos Betsis >>> >>> >>> On Fri, Sep 11, 2020 at 11:01 AM Dominik Holler <dholler(a)redhat.com&gt; >>> wrote: >>> >>>> >>>> >>>> On Thu, Sep 10, 2020 at 6:26 PM Konstantinos B <k.betsis(a)gmail.com&gt; >>>> wrote: >>>> >>>>> Hi all >>>>> >>>>> We have a small installation based on OVIRT 4.3. >>>>> 1 Cluster is based on Centos 7 and the other on OVIRT NG Node image. >>>>> >>>>> The environment was stable till an upgrade took place a couple of >>>>> months ago. >>>>> As such we had to re-install one of the Centos 7 node and start from >>>>> scratch. >>>>> >>>> >>>> To trigger the automatic configuration of the host, it is required to >>>> configure ovirt-provider-ovn as the default network provider for the >>>> cluster before adding the host to oVirt. >>>> >>>> >>>>> Even though the installation completed successfully and VMs are >>>>> created, the following are not working as expected: >>>>> 1. ovn geneve tunnels are not established with the other Centos 7 >>>>> node in the cluster. >>>>> 2.
