MySQL 在MyISAM表中DML生成: “ERROR 144 (HY000): Table ???? is marked as crashed and last (automatic?) repair failed”
适用于:
MySQL服务器版本5.0及以上
本文信息适用于所有平台。
症状
在MyISAM表使用DML (如inserts, deletes, selects,等),以下错误可能发生:
101001 14:57:57 [ERROR] ./bin/mysqld: Table ‘./test/t2′ is marked as crashed and last (automatic?) repair failed
原因
Bug 11764345 –SHOW TABLE STATUS + SMALL MYISAM_SORT_BUFFER_SIZE IN REPAIR, TABLE CRASHE
当小的myisam_sort_buffer_size与repair by sort发生,且有人运行 ‘show
table status’ 或引用表selects from information_schema tables,错误在日志中出现。当check table在运行时,表不显示损坏。
解决方案
变通方案
1. 在错误表中运行REPAIR TABLE来修复表
2. 增加变量myisam_sort_buffer_size的值来防止bug的发生
永久解决方案
