There are 2 major types of MCE errors, a notice or warning error, and a fatal execption. The warning will be logged by a Machine Check Event logged notice in your system logs, and can be later viewed via some Linux utilities. A fatal MCE will cause the machine to stop responding and the details of the MCE will be printed out to the systems console.What causes MCE errors?There most common reason for MCE events to occur are:1.Memory errors or Error Correction Code (ECC) problems2.Inadequate cooling / processor over-heating3.System bus errors4.Cache errors in the processor or hardware##一般来说当有错误提示时需要优先注意内存问题但由于现在内存控制器是集成在cpu里所以有个别情况是由CPU问题引起的##Installmcelog-1.0_pre3_p20120918.tar.gzMcelog安装#tar -zxvf mcelog-1.0_pre3_p20120918.tar.gz 解压出来#cd andikleen-mcelog-0f5d023 进入解压出来的文件夹#make#make install 编译和安装Mcelog相关文件/dev/mcelog 设备文件/var/log/mcelog messages日志文件/etc/mcelog/mcelog.conf配置文件/var/run/mcelog.pid默认故障日志只记录在/var/log/mcelog并不记录到系统日志中。如果需要在系统日志中也体现需修改/etc/mcelog/mcelog.conf文件将前面#去掉并保存。Mcelog相关设置1.mcelog的随系统启动查看boot下的config文件可以看到mce模块随机启动2.配置mcelog后台运行#mcelog --daemon3.查看mcelog日志文件由于各厂家服务器内存槽位设计可能不同这边关于错误中的cpu0 bank5内存槽位定位不做讨论。
