ovn_node02
二、问题
1.南向控制器节点名称报错
(1)报错
ovn_central文章来源:https://www.toymoban.com/news/detail-858842.html
Chassis "a01fe9cb-463f-4d2d-b3bb-810b6a923a01"
……
Chassis "37752d67-f6d8-47b7-9ce0-248eb2c1f1fc"
……
ovn_node01
……
Port "ovn-37752d-0"
……
ovn_node02
……
Port "ovn-a01fe9-0"
……
(2)原因分析
系统重启后,OVN系统ID丢失。
(3)解决方法
设置OVN系统ID,名字显示为Chassis:
ovn_node01
ovs-vsctl set open . external-ids:system-id=node01
ovs-vsctl show
ovn_node02
ovs-vsctl set open . external-ids:system-id=node02
ovs-vsctl show
ovn_central
