在给mysql数据库备份时，报错：
mysqldump: Got error: 145: Table '.shengdaxcompre_forum_thread' is marked as c
rashed and should be repaired when using LOCK TABLES
如上错误的解决方法如下：
1、进入数据库对该表进行检测：
mysql> check tables pre_forum_thread;
+------------------------------+-------+----------+-----------------------------
--------------------------+
| Table | Op | Msg_type | Msg_text
|
+------------------------------+-------+----------+-----------------------------
--------------------------+
| shengdaxcom.pre_forum_thread | check | warning | Table is marked as crashed
|
| shengdaxcom.pre_forum_thread | check | warning | 1 client is using or hasn't
closed the table properly |
| shengdaxcom.pre_forum_thread | check | error | Size of indexfile is: 845824
Should be: 846848 |
| shengdaxcom.pre_forum_thread | check | error | Corrupt
|
+------------------------------+-------+----------+-----------------------------
--------------------------+
4 rows in set (0.06 sec)
2、使用repair解决方法：
mysql> repair tables pre_forum_thread;
+------------------------------+--------+----------+----------+
| Table | Op | Msg_type | Msg_text |
+------------------------------+--------+----------+----------+
| shengdaxcom.pre_forum_thread | repair | status | OK |
+------------------------------+--------+----------+----------+
1 row in set (0.31 sec)
再次进行dump备份就可以了。
其他参考:
只要在mysqldump的时候加上--lock-tables=false就可以解决问题。
mysqldump -u root -pMyPassword DbName --lock-tables=false > data.sql
