症状
当尝试访问表test.t1时,出现以下错误:
150512 16:30:01 [ERROR] MySQL is trying to open a table handle but the .ibd file for table test/t1 does not exist. Have you deleted the .ibd fil e from the database directory under the MySQL datadir, or have you used DISCARD TABLESPACE? See http://dev.mysql.com/doc/refman/5.1/en/innodb‐troubl eshooting.html how you can resolve the problem.
原因
这个问题的原因是缺少相关表t1中的.ibd文件。这表示没有任何语句可以对表T1运行。
由错误本身以及检查该文件是否存在确认:
shell> ls ‐lahR /var/lib/mysql/ /var/lib/mysql/test: total 21G drwx‐‐‐‐‐‐ 2 mysql mysql 32K may 12 03:55 . drwxr‐xr‐x 7 mysql mysql 4,0K nov 10 2014 .. ... ‐rw‐rw‐‐‐‐ 1 mysql mysql 8,6K may 12 03:16 t.frm ‐rw‐rw‐‐‐‐ 1 mysql mysql 20M may 12 13:37 t.ibd ‐rw‐rw‐‐‐‐ 1 mysql mysql 8,5K ago 10 2014 t1.frm ‐rw‐rw‐‐‐‐ 1 mysql mysql 8,5K may 12 03:16 t2.frm ‐rw‐rw‐‐‐‐ 1 mysql mysql 128K may 12 03:16 t2.ibd
进一步查看MySQL错误日志,当错误开始出现,即truncate table在运行时,就能看到。该语句无法重建各自的.ibd文件,所以文件丢失:
140810 5:05:03 InnoDB: TRUNCATE TABLE test/t1 failed to create a new tablespace
解决方案
重建表:
Drop table: mysql> DROP TABLE test.t1; The following error may be seen in the error log afterwards, but it's basically saying the tablespace was still present in InnoDB Data Dictionary and that eventually was removed: 150513 14:49:08 InnoDB: Error: table 'test/t1' InnoDB: in InnoDB data dictionary has tables pace id 607381, InnoDB: but tablespace with that id or name does not exist. Have InnoDB: you deleted or moved .ibd files? InnoDB: This may also be a table created with CREATE TEMPORARY TABLE InnoDB: whose .ibd and .frm files MySQL automatically removed, but t he InnoDB: table still exists in the InnoDB internal data dictionary. InnoDB: Please refer to InnoDB: http://dev.mysql .com/doc/refman/5.1/en/innodb‐troubleshootingdatadict.html InnoDB: for how to resolve the issue. InnoDB: We removed now the InnoDB int ernal data dictionary entry InnoDB: of table `test`.`t1`.
- 再次Create table
- 测试表的访问来确认现在能运行 (ex: optimize table)
mysql> OPTIMIZE TABLE test.t1;
