Hello Gianluca, Please check on the engine what hosts are registered on ovn-north: #ovn-sbctl show For each registered host you should see something like: Chassis "69b6b2a6-5afb-4908-8d66-c648cbe09ba8" hostname: "f43" Encap geneve ip: "192.168.120.43" .... I would assume you have some unwanted entries there (10.4.168.74) To get rid of this please use: # ovn-sbctl chassis-del <chassis id> // for example: ovn-sbctl chassis-del 69b6b2a6-5afb-4908-8d66-c648cbe09ba8 Please let me know if this helps. Note also that you would have to runplug/plug any vnics on any vm's you have on those two hosts. Marcin On Tue, Oct 3, 2017 at 3:41 PM, Gianluca Cecchi <gianluca.cecchi@gmail.com> wrote:
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@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@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
