错误日志：

Cause: java.sql.SQLException: Can't create/write to file '/tmp/MYmZiY2i' (Errcode: 28 - No space left on device)\n; SQL []

重点内容：Errcode: 28 - No space left on device

那么这些System Error Code在Linux下分别代表什么意思呢？其实如果遇到错误日志里有这些对应的代码，使用MySQL自带的命令工具perror查看一下具体信息即可。非常简单方便。


[root@localhost ~]# perror 2
OS error code   2:  No such file or directory
[root@localhost ~]# perror 28
OS error code  28:  No space left on device
[root@localhost ~]# perror 31
OS error code  31:  Too many links
#如果你要查看一个范围的Operating system error，可以使用下面命令
[root@localhost ~]# perror `seq 0 10`
OS error code   0:  Success
OS error code   1:  Operation not permitted
OS error code   2:  No such file or directory
OS error code   3:  No such process
OS error code   4:  Interrupted system call
OS error code   5:  Input/output error
OS error code   6:  No such device or address
OS error code   7:  Argument list too long
OS error code   8:  Exec format error
OS error code   9:  Bad file descriptor
OS error code  10:  No child processes
[root@localhost ~]#
