标题: linux系统硬盘检测健康状态
smartctl -i /dev/sda

正常情况下显示如下

=== START OF INFORMATION SECTION ===

SMART support is: Enabled

在这里，如果看到SMART support is: Enabled，则表示SMART已启用

如果未启用我们需要执行如下命令，启动SMART：

复制代码如下:

smartctl –smart=on –offlineauto=on –saveauto=on /dev/sda

再次查看如果变成SMART support is: Enabled，则表示SMART已开启

查看硬盘当前的健康状态使用如下命令
smartctl -H /dev/sda

显示如下

=== START OF READ SMART DATA SECTION ===
SMART overall-health self-assessment test result: PASSED

请注意result后边的结果：PASSED，这表示硬盘健康状态良好
如果这里显示Failure，那么最好立刻给服务器更换硬盘。

执行如下命令可以看到详细的参数：smartctl -A /dev/sda

显示结果如下
