Re: [ovs-dev] [ovn] ha-chassis-group false positive failover

Hi Vladislav, (Sorry I didn't notice your update until now when reading the discussion of your OVN patch) I think a simple solution is to update the hardcoded 60s probe in OVS to 0, for the pre-created punix mgmt controller. We could make it configurable, but it may not make much sense since it

Hi, I’ve sent the first part (OF probing disable) - https://patchwork.ozlabs.org/project/ovn/patch/20230608141555.1339905-1-odiv...@gmail.com/ Regarding configuration on the OVS side, I see it’s not working like I wrote before, I’ve deceived myself :) I’ve written some code in ovn-controller,

Re: [ovs-dev] [ovn] ha-chassis-group false positive failover

And as a follow-up, I see sometimes next error message in ovn-controller log, though there is a configured much higher limit in seconds for inactivity probe value for the chassis: ovs|04426|rconn|ERR|unix:/run/openvswitch/br-int.mgmt: no response to inactivity probe after 8 seconds,

[ovs-dev] [ovn] ha-chassis-group false positive failover

Hi all, I’m facing a false positive failover in the event of openflow connection got dropped after inactivity probe timeout due to high load of ovn-controller handling huge amount of ovsdb updates. I wonder wether its a bug or I have to tune any specifics. See ovn-controller logs:
