[jira] [Commented] (IOTDB-3548) [cluster]can not create timeseries when start 3C2D（or stop a datanode of 3C3D）
[ https://issues.apache.org/jira/browse/IOTDB-3548?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17557843#comment-17557843 ]
FengQingxin commented on IOTDB-3548:
------------------------------------
三节点三副本：
schema_replication_factor=3
data_replication_factor=3
停掉一个datanode之后就不再支持查询和写入

> Reproduce steps：
> 1. Modify config file as 3C3D:
> schema_replication_factor=3
> data_replication_factor=1
> 2. Start 3C
> 3.Start 2D
> 4. using iotdb-cli to execute below sql:
> set storage group to root.sg;
> create timeseries root.sg.d.s1 with datatype=INT32,encoding=RLE,compression=snappy;
> create timeseries root.sg.d.s2 with datatype=INT32,encoding=RLE,compression=snappy;
> create timeseries root.sg.d.s3 with datatype=INT32,encoding=RLE,compression=snappy;
> insert into root.sg.d(time,s1,s2,s3) values(1,1,2,3);
> insert into root.sg.d(time,s1,s2,s3) values(2,1,2,3);
> 5.Got below error msg:
