<p>有客户sql server数据库由于异常断电,导致数据库访问异常<br />
<a href="https://www.xifenfei.com/wp-content/uploads/2025/04/QQ20250422-132721.png"><img src="https://www.xifenfei.com/wp-content/uploads/2025/04/QQ20250422-132721.png" alt="QQ20250422-132721" width="734" height="432" class="alignleft size-full wp-image-11428" /></a><br />
<hr />
对其做dbcc检查发现报：检查已终止。收集事实数据时检测到错误。可能是 tempdb 空间用尽或某个系统表不一致。请检查前面的错误消息。错误<br />
<a href="https://www.xifenfei.com/wp-content/uploads/2025/04/QQ20250422-121636.png"><img src="https://www.xifenfei.com/wp-content/uploads/2025/04/QQ20250422-121636.png" alt="QQ20250422-121636" width="668" height="215" class="alignleft size-full wp-image-11429" /></a><br />
<hr />
查看sql server 日志,发现报错日志内容为:<br />
04/22/2025 10:50:26,spid58,未知,DBCC CHECKDB (SHINVA) WITH no_infomsgs executed by sa terminated abnormally due to error state 5. Elapsed time: 0 hours 0 minutes 1 seconds.<br />
04/22/2025 10:50:26,spid58,未知,The Database ID 7<c/> Page (1:147440)<c/> slot 0 for LOB data type node does not exist. This is usually caused by transactions that can read uncommitted data on a data page. Run DBCC CHECKTABLE.<br />
04/22/2025 10:50:26,spid58,未知,错误: 7105，严重性: 22，状态: 9。<br />
对于这种情况,尝试重建LDF,和REPAIR_ALLOW_DATA_LOSS方案都失败,最终确认通过逻辑迁移的方式完成恢复,然后再次尝试dbcc一切正常,完成本次恢复任务<br />
