- 问题的具体描述
测试集群一共2台机器，每台机器分别部署了1个graphd、metad、storaged服务，创建了一个测试图空间demo2,设置10分区2副本，建图语句如下：
# Create Space
CREATE SPACE `demo2` (partition_num = 10, replica_factor = 2, charset = utf8, collate = utf8_bin, vid_type = FIXED_STRING(32));
:sleep 20;
USE `demo2`;
# Create Tag:
CREATE TAG `player` ( `name` string NULL, `age` int64 NULL) ttl_duration = 0, ttl_col = "";
CREATE TAG `team` ( `name` string NULL) ttl_duration = 0, ttl_col = "";
# Create Edge:
CREATE EDGE `follow` ( `degree` int64 NULL) ttl_duration = 0, ttl_col = "";
CREATE EDGE `serve` ( `start_year` int64 NULL, `end_year` int64 NULL) ttl_duration = 0, ttl_col = "";
:sleep 20;
# Create Index:
CREATE TAG INDEX `player_index_0` ON `player` ();
CREATE TAG INDEX `player_index_1` ON `player` ( `name`(20));
当我停掉1台其中一台机器的storaged服务，
就会导致无法查询，查询会报错，报错如下：

以上问题是什么原因，我设置2副本，理论上停掉1个storaged服务，还有另一个stroaged服务有全量数据能够提供查询，应该怎么解决。
