Hi Ben: I cannot see the patch series on the patchwork. Is it due to mail server sync issue or something else? Not sure if its appropriate to try out https://github.com/blp/ovs-reviews/commits/raft-fixes since it has the patches in review in addition to some other patches?

[ovs-discuss] Raft issues while removing a node
Hi, I am facing trouble in graceful removal of node in a 3 Node RAFT setup. Node1 : $ovn-ctl --db-nb-addr=10.8.49.184 --db-nb-port=6641 --db-nb-create-insecure-remote=yes --db-nb-cluster-local-proto=tcp --db-nb-cluster-local-port=6643 --db-nb-cluster-local-addr=10.8.49.184 start_nb_ovsdb $ovn-ctl --db-sb-addr=10.8.49.184 --db-sb-port=6642 --db-sb-create-insecure-remote=yes --db-sb-cluster-local-proto=tcp --db-sb-cluster-local-port=6644 --db-sb-cluster-local-addr=10.8.49.184 start_sb_ovsdb $ovn-ctl start_northd --ovn-manage-ovsdb=no --ovn-northd-nb-db="tcp: 10.8.49.184:6641,tcp:10.8.49.181:6641,tcp:10.8.49.173:6641" --ovn-northd-sb-db="tcp:10.8.49.184:6642,tcp:10.8.49.181:6642 tcp: 10.8.49.173:6642" Node 2: $ovn-ctl --db-nb-addr=10.8.49.181 --db-nb-port=6641 --db-nb-create-insecure-remote=yes --db-nb-cluster-local-proto=tcp --db-nb-cluster-local-port=6643 --db-nb-cluster-local-addr=10.8.49.181 --db-nb-cluster-remote-addr=10.8.49.184 start_nb_ovsdb $ovn-ctl --db-sb-addr=10.8.49.181 --db-sb-port=6642 --db-sb-create-insecure-remote=yes --db-sb-cluster-local-proto=tcp --db-sb-cluster-local-port=6644 --db-sb-cluster-local-addr=10.8.49.181 --db-sb-cluster-remote-addr=10.8.49.184 start_sb_ovsdb Node 3: $ovn-ctl --db-nb-addr=10.8.49.173 --db-nb-port=6641 --db-nb-create-insecure-remote=yes --db-nb-cluster-local-proto=tcp --db-nb-cluster-local-port=6643 --db-nb-cluster-local-addr=10.8.49.173 --db-nb-cluster-remote-addr=10.8.49.184 start_nb_ovsdb $ovn-ctl --db-sb-addr=10.8.49.173 --db-sb-port=6642 --db-sb-create-insecure-remote=yes --db-sb-cluster-local-proto=tcp --db-sb-cluster-local-port=6644 --db-sb-cluster-local-addr=10.8.49.173 --db-sb-cluster-remote-addr=10.8.49.184 start_sb_ovsdb Now I forcefully stopped northd on Node 1 (Either by doing ovn-central stop service or forcefully closing the vm in which node1 is running). Now Node 3 was elected as leader from remaining nodes(verified by running $ovs-appctl -t /var/run/openvswitch/ovnnb_db.ctl cluster/status OVN_Northbound ) $ovs-appctl -t /var/run/openvswitch/ovnsb_db.ctl cluster/status OVN_Southbound ) Now i tried to remove node using unixctl on the non-leader node. $ovs-appctl -t /var/run/openvswitch/ovnsb_db.ctl cluster/kick OVN_Southbound Ideally it should remove node1 but this removed node 2 itself from the cluster and making the cluster unavailable. Could you please let us know, how to do a graceful node removal from cluster if the node becomes unavailable?
