clickhouse之readonly解决方法

1，问题描述

日志报错写入ck报错：ru.yandex.clickhouse.except.ClickHouseUnknownException: ClickHouse exception, code: 1002, host: 192.16.1.19, port: 8123; Code: 242. DB::Exception: Table is in readonly mode: replica_path=/clickhouse/tables/datap_one_rep/db_com_aaa/dwd_visit_users_log_local/2/replicas/everdata19. (TABLE_IS_READ_ONLY) (version 23.2.5.46 (official build))

2,问题排查

SELECT

table,

zookeeper_path,

replica_path

FROM clusterAllReplicas('eversec_one_rep', 'system', 'replicas')

WHERE is_readonly ;

找到readonly的节点后，登录到对应的节点上执行一下操作

例如19节点：

1,）DETACH TABLE 库名.表名；

2）SYSTEM DROP REPLICA 'ever19' FROM ZKPATH '/clickhouse/tables/ever_one_rep/db_com_pingan/表名/2';

3）ATTACH TABLE d库名.表名;

4） SYSTEM RESTORE REPLICA 库名.表名;

5）SYSTEM SYNC REPLICA 库名.表名;
