mysql> repair table sudops_options;
+--------------------------------+--------+----------+------------------------------------------------------+
| Table                          | Op     | Msg_type | Msg_text                                             |

repair之后再次check下表状态：

mysql> check table sudops_options;
+--------------------------------+-------+----------+----------+
| Table                          | Op    | Msg_type | Msg_text |
+--------------------------------+-------+----------+----------+
| sudops_com.sudops_options      | check | status   | OK       |
+--------------------------------+-------+----------+----------+
1 row in set (0.03 sec)

可以看到已经OK了 ：）

再次看下mysql的 errlog：
