经常有些计算结点被移除了,或者是暂时不想用了,但还是出现在 nova service-list 列表中,在 horizon 中还是看得到,状态是 disabled

可以通过直接在数据库中删除这个计算结点的信息来实现完全删除一个计算结点的功能
mysql> delete from compute_nodes where service_id=6;
ERROR 1451 (23000): Cannot delete or update a parent row: a foreign key constraint fails (`nova`.`compute_node_stats`,
CONSTRAINT `fk_compute_node_stats_compute_node_id` FOREIGN KEY (`compute_node_id`) REFERENCES `compute_nodes` (`id`))
有外键依赖,同时在另外一张表删除相关行
mysql> delete from compute_node_stats where compute_node_id=1;
Query OK, 18 rows affected (0.01 sec)
mysql> delete from compute_nodes where service_id=6;
Query OK, 1 row affected (0.00 sec)
mysql> delete from services where id=6;
Query OK, 5 rows affected (0.03 sec)
搞掂:
