[ovirt-users] OVN and change of mgmt network

[Gianluca Cecchi]

Hello,
I previously had OVN running on engine (as OVN provider with northd and
northbound and southbound DBs) and hosts (with OVN controller).

After changing mgmt ip of hosts (engine has retained instead the same ip),
I executed again on them the command:

vdsm-tool ovn-config <ip_of_engine> <nel_local_ip_of_host>

Now I think I have to clean up some things, eg:

1) On engine
where I get these lines below

systemctl status ovn-northd.service -l
. . .
Sep 29 14:41:42 ovmgr1 ovsdb-server[940]: ovs|00005|reconnect|ERR|tcp:
10.4.167.40:37272: no response to inactivity probe after 5 seconds,
disconnecting
Oct 03 11:52:00 ovmgr1 ovsdb-server[940]: ovs|00006|reconnect|ERR|tcp:
10.4.167.41:52078: no response to inactivity probe after 5 seconds,
disconnecting

The two IPs are the old ones of two hosts
It seems that a restart of the services has fixed...
Can anyone confirm if I have to do anything else?

2) On hosts (there are 3 hosts with OVN on ip 10.4.192.32/33/34)
where I currently have this output

[root at ov301 ~]# ovs-vsctl show
3a38c5bb-0abf-493d-a2e6-345af8aedfe3
    Bridge br-int
        fail_mode: secure
        Port "ovn-1dce5b-0"
            Interface "ovn-1dce5b-0"
                type: geneve
                options: {csum="true", key=flow, remote_ip="10.4.192.32"}
        Port "ovn-ddecf0-0"
            Interface "ovn-ddecf0-0"
                type: geneve
                options: {csum="true", key=flow, remote_ip="10.4.192.33"}
        Port "ovn-fd413b-0"
            Interface "ovn-fd413b-0"
                type: geneve
                options: {csum="true", key=flow, remote_ip="10.4.168.74"}
        Port br-int
            Interface br-int
                type: internal
    ovs_version: "2.7.2"
[root at ov301 ~]#

The IPs of kind 10.4.192.x are ok.
But there is a left-over of an old host I initially used for tests,
corresponding to 10.4.168.74, that now doesn't exist anymore

How can I clean records for 1) and 2)?

Thanks,
Gianluca
