mysql 的一個從庫報錯：
Could not execute Write_rows event on table xxx.xxxx_tmp_tj; Error writing file '/tmp/MLLGyECY' (Errcode: 28 - No space left on device), Error_code: 3; Error writing file 'mysql-bin' (errno: 28 - No space left on device), Error_code: 1026; Writing one row to the row-based binary log failed, Error_code: 1534; handler error HA_ERR_RBR_LOGGING_FAILED; the event's master log mysql-bin.003482, end_log_pos 119034357
Replicate_Ignore_Server_Ids:
df -h 查看 /tmp 目錄6.3G，應該是大事務導致需要很大的臨時空間，導致6.3G不夠用。所以報錯。
修改my.cnf, 在 [mysqld] 下面加上配置項：
tmpdir = /data/tmp
重啟mysqld.
解決問題。
官網文檔 關於 tmpdir 的說明：
The path of the directory to use for creating temporary files. It might be useful if your default /tmp directory resides on a partition that is too small to hold temporary tables. This option accepts several paths that are used in round-robin fashion. Paths should be separated by colon characters (:) on Unix and semicolon characters (;) on Windows. If the MySQL server is acting as a replication slave, you should not set --tmpdir to point to a directory on a memory-based file system or to a directory that is cleared when the server host restarts. For more information about the storage location of temporary files, see Section B.5.3.5, “Where MySQL Stores Temporary Files”. A replication slave needs some of its temporary files to survive a machine restart so that it can replicate temporary tables or LOAD DATA INFILE operations. If files in the temporary file directory are lost when the server restarts, replication fails.
