mysql怎麼解決提示Got error 28 from storage engine問題
資料庫用的臨時目錄空間不夠。
解決辦法:
清空/tmp目錄,或者修改my.cnf中的tmpdir參數,指向具有足夠空間目錄
mysql怎麼解決提示Got error 28 from storage engine的問題?
解決方案:
1、在資料庫所在的linux伺服器上,用df查看磁碟使用情況。
註:df是基於文件系統總體來計算,通過文件系統中未分配空間來確定系統中已經分配空間的大小。df命令可以獲取硬碟佔用了多少空間,還剩下多少空間,它也可以顯示所有文件系統對i節點和磁碟塊的使用情況。
2、在資料庫所在的linux伺服器上,用du查看目錄大小。
註:du的英文為:disk usage,含義是磁碟空間使用情況,功能是逐級進入指定目錄的每一個子目錄並顯示該目錄佔用文件系統數據塊的情況,如果沒有指定目錄,則對當前的目錄進行統計。
3、刪除相應的大文件,或者表數據。

你應該是使用的innodb,檢查你的my.cnf或my.ini,裡面會有一個參數innodb_force_recovery,你看看他的值,默認是沒有這個參數,沒有的話,他的默認值是0,這個參數的值如果大於0,innodb會被禁止使用insert、update、delete命令,你可以嘗試將他的值設置為0,看看你的mysql是否正常,如果正常就用就行了。
mysql 錯誤 以下是錯誤日誌的內容 我使用fleaphp 弄的網站 fleaphp 提示的錯誤是 SQL 錯誤消息: “Got err
“Column count of mysql.event is wrong”,你的mysql.event表壞了,在bin目錄下運行mysql_upgrade.exe執行下修復。
下面提示存儲引擎錯誤,估計是你的表由於計算機異常重啟導致物理損壞了。
用check table xxxx檢查下表吧。
mysql federated經常報錯:Got an error writing communication packets
可以建立一個Events定時對Federated的表進行flush。具體可以見
Related to Federated Table :
Whenever a query is issued against a federated table, a single/multiple [ depends on Number = table_open_cache_instances] connection will be created from the DB instance hosting the federated table to the DB instance hosting the main table. If those single/mutiple connection on the DB instance hosting main table expires because of [wait_timeout,connect_timeout] or if those gets terminated manually , any new queries on federated table will result in “ERROR 1158 (08S01) at line 1: Got an error reading communication packets” on the DB instance hosting the federated table.
Reason : Flushing of the federated table does not happen properly from the table_open_cache_instances ,
Solution : To avoid this, the temporary solution is to manually/forcefully flush only those federated tables once before every [wait_timeout,connect_timeout] seconds. In our case we put the flush command in event_scheduler since the number of federated tables were very less and we knew exactly which federated tables were rarely getting queried with gap of more than [wait_timeout,connect_timeout] seconds. This used to affect even our MEB backup when it used execute “flush tables with READ lock”.
flush table federated_table_name; — executed every 4 hours
Key : The frequency with which it errors depends on how many table_open_cache_instances is configured on the Instance.
Since then, after putting the manual flush of federated tables with a frequence less than [wait_timeout,connect_timeout] , this issue has not showed up. Hope this helps.
