Description of problem: when the system-id changes, the table chassis_private doesn't clean the old information Version-Release number of selected component (if applicable): # rpm -qa|grep ovn ovn2.13-host-20.06.2-1.el8fdp.x86_64 ovn2.13-20.06.2-1.el8fdp.x86_64 ovn2.13-central-20.06.2-1.el8fdp.x86_64 How reproducible: always Steps to Reproduce: at first,set the env as below: #ovn-sbctl show Chassis hv0 hostname: dell-per730-57.rhts.eng.pek2.redhat.com Encap geneve ip: "20.0.10.26" options: {csum="true"} Chassis hv1 ----------------this name is hv1 hostname: dell-per730-19.rhts.eng.pek2.redhat.com Encap geneve ip: "20.0.10.25" options: {csum="true"} then config the ls and ports. change the system-id: ovs-vsctl set open . external_ids:system-id=local then, #ovn-sbctl show Chassis hv0 hostname: dell-per730-57.rhts.eng.pek2.redhat.com Encap geneve ip: "20.0.10.26" options: {csum="true"} Chassis local ----------------now the name is local hostname: dell-per730-19.rhts.eng.pek2.redhat.com Encap geneve ip: "20.0.10.25" options: {csum="true"} then check the chassis_private table,there are three items: # ovn-sbctl list chassis_private _uuid : b612ba1c-5434-4864-be37-02fa68a056e1 chassis : fd1b04b6-972c-4dce-b24e-7a0ac31dcf94 external_ids : {} name : hv0 nb_cfg : 102 _uuid : 70346152-cece-44b9-b39c-dbf0f5845e35 chassis : d3831b51-8ddd-4b4c-8844-0a225e738f36 external_ids : {} name : hv1 ---------------this item should be cleanup nb_cfg : 0 _uuid : 58628c1f-b623-4a98-af4f-821a9d101aba chassis : d3831b51-8ddd-4b4c-8844-0a225e738f36 external_ids : {} name : local nb_cfg : 102 but we can see the table chassis clean the old item: # ovn-sbctl list chassis _uuid : d3831b51-8ddd-4b4c-8844-0a225e738f36 encaps : [bc8869d2-130a-4754-ac51-52dd05576c1e] external_ids : {datapath-type="", iface-types="erspan,geneve,gre,internal,ip6erspan,ip6gre,lisp,patch,stt,system,tap,vxlan", is-interconn="false", ovn-bridge-mappings="", ovn-chassis-mac-mappings="", ovn-cms-options="", ovn-monitor-all="false"} hostname : dell-per730-19.rhts.eng.pek2.redhat.com name : local nb_cfg : 0 other_config : {datapath-type="", iface-types="erspan,geneve,gre,internal,ip6erspan,ip6gre,lisp,patch,stt,system,tap,vxlan", is-interconn="false", ovn-bridge-mappings="", ovn-chassis-mac-mappings="", ovn-cms-options="", ovn-monitor-all="false"} transport_zones : [] vtep_logical_switches: [] _uuid : fd1b04b6-972c-4dce-b24e-7a0ac31dcf94 encaps : [2bd0a98d-71f0-45eb-9537-33dc7f80634f] external_ids : {datapath-type="", iface-types="erspan,geneve,gre,internal,ip6erspan,ip6gre,lisp,patch,stt,system,tap,vxlan", is-interconn="false", ovn-bridge-mappings="", ovn-chassis-mac-mappings="", ovn-cms-options="", ovn-monitor-all="false"} hostname : dell-per730-57.rhts.eng.pek2.redhat.com name : hv0 nb_cfg : 0 other_config : {datapath-type="", iface-types="erspan,geneve,gre,internal,ip6erspan,ip6gre,lisp,patch,stt,system,tap,vxlan", is-interconn="false", ovn-bridge-mappings="", ovn-chassis-mac-mappings="", ovn-cms-options="", ovn-monitor-all="false"} transport_zones : [] vtep_logical_switches: [] Actual results: the old item is in the table Expected results: the old item should be cleanup Additional info:
