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
