一台mysql 服务器，机器意外重启后，N个表报错，想必你已经知道库的引擎是myisam 的了，太悲催，太蛋碎了，先看看报错信息：

mysql> desc PARTITION_KEYS;
ERROR 130 (HY000): Incorrect file format 'PARTITION_KEYS'
mysql> check table PARTITION_KEYS;
+-------------------------+-------+----------+----------------------------------------+
| Table                   | Op    | Msg_type | Msg_text                               |
