硬碟空間滿導致mysql ibd檔案被刪後提示Tablespace is missing for table 'db_rsk/XXX"

昨天一早，開發人員反饋說一個測試環境報Tablespace is missing for table ‘db_rsk/XXX"，周末剛升級過，特地讓開發回去查了下，說指令碼中肯定沒有drop table的操作。datadir下檢查了下，發現frm檔案在的ibd檔案沒有了，bing了下，沒發現類似異常。於是先回到mysql.err往回搜尋，半天后發現上周五下午mysql出現了一次異常宕機，說是磁碟空間不足了，看日誌該檔案被損壞了，如下：

2016-11-12 11:31:00 28443 [ERROR] Error writing file ‘/usr/local/Percona-Server-5.6.30-rel76.3-Linux.x86_64.ssl101/data/tmp-demo-slow.log‘ (errno: 1 - No space left on device)

隨後後台就一直報 ibd file is missing。

找到問題了，解決就方便了，找個備份，把這張表重新匯入進去就可以了。

這說回來，mysql的容錯程度比oracle好多了，oracle異常後恢複的時候經常要resetlogs，有些時候連resetlogs也會失敗。
