Oceanbase-failed to merge partition

与数据交流的路上2026-04-23 10:36

一、背景

收到了oceanabse的报警，查看错误码发现这种为重试，一般无需关注，如果后续持续告警需要关注

bash 复制代码

日志级别：WDIAG，关键字=failed to merge partition，错误码=4023

二、排查与处理

本着学习的精神，我们也看下是否自动成功

1.查看对应时间的合并记录

通过合并历史查看，可以确定 merge 已经在下次成功了

bash 复制代码

SELECT tenant_id, ls_id, tablet_id, type,        start_time, finish_time,        execute_time,        comments FROM GV$OB_TABLET_COMPACTION_HISTORY WHERE tenant_id = 1002   AND start_time between "2026-04-22 07:37:00" and "2026-04-22 07:45:00" ORDER BY start_time DESC LIMIT 200;

三、其他补充查询

1.Memstore 内存使用

sql 复制代码

SELECT svr_ip, tenant_id,
       round(active_span   /1024/1024/1024, 2) AS active_gb,
       round(freeze_trigger/1024/1024/1024, 2) AS freeze_trigger_gb,
       round(memstore_used /1024/1024/1024, 2) AS memstore_used_gb,
       round(memstore_limit/1024/1024/1024, 2) AS memstore_limit_gb,
       freeze_cnt
FROM GV$OB_MEMSTORE
WHERE tenant_id = 1002;

2.compaction 整体进度

sql 复制代码

SELECT tenant_id, type, zone, status,
       total_tablet_count,
       unfinished_tablet_count,
       start_time,
       estimated_finish_time,
       comments
FROM GV$OB_COMPACTION_PROGRESS
WHERE tenant_id = 1002;

3.tablet级别compaction 进度

sql 复制代码

SELECT tenant_id, ls_id, tablet_id, type, status,
       create_time, start_time, estimated_finish_time
FROM GV$OB_TABLET_COMPACTION_PROGRESS
WHERE tenant_id = 1002;
