使用CnosDB删除VNode后写入数据失败，VNode未自动创建

环境信息 #

• CnosDB版本：ea47f4eb81cee966648f95d4ad34044e8a6f28d3
• 集群配置：2个数据节点，3个元节点

操作过程 #

1. 首次写入数据成功 #

curl -XPOST -u "root:" "http://127.0.0.1:8902/api/v1/write?db=public" -d "ma,ta=a fa=1"
select * from ma;
+----------------------------+----+-----+
| time | ta | fa |
+----------------------------+----+-----+
| 2023-04-27T10:14:25.373394 | a | 1.0 |
+----------------------------+----+-----+

2. 删除唯一VNode #

DROP VNODE 6;
select * from ma;
Query took 0.021 seconds.

3. 第二次写入失败，VNode未自动创建 #

curl -XPOST -u "root:" "http://127.0.0.1:8902/api/v1/write?db=public" -d "ma,ta=a fa=1"
select * from ma;
Query took 0.020 seconds.

4. 写入另一数据节点同样失败 #

curl -XPOST -u "root:" "http://127.0.0.1:8912/api/v1/write?db=public" -d "ma,ta=a fa=1"
# 在8902和8912节点分别执行查询
select * from ma;
Query took 0.020 seconds.

预期行为 #

无论CnosDB的VNode是否被删除，数据写入都不应受到影响，系统应自动重建所需VNode以完成写入操作。
