Hi Yun: For changing inactivity probe which is 5 sec default, you need to create connection entry both for sb and nb db. ovn-nbctl -- --id=@conn_uuid create Connection \ target="<ptcp/ssl>\:<your-pord>\:<vip-ip>" \ inactivity_probe=<value> -- set NB_Global . connections=@conn_uuid
ovn-nbctl set connection . inactivity_probe=<value> will then work! To tune the election timer for raft on say nb db, you can tune with below command: ovs-appctl -t /var/run/openvswitch/ovnnb_db.ctl cluster/change-election-timer OVN_Northbound <value> You can run similar settings for sb db for tuning the value On Wed, Feb 5, 2020 at 4:00 AM taoyunupt <taoyun...@126.com> wrote: > Hi,Numan, > I happend the problem that there are frequently elections > in RAFT cluster members .
