Debian 10.05查看硬盘温度和smart

最近组了一个raid 1，用的小机箱，温度比较高，所以想看下硬盘的温度。在debian里面，安装smartmontools即可。

一，安装smartmontools

apt-get install -y smartmontools

二，列出硬盘

fdisk -l

三，查看硬盘信息

smartctl -a /dev/sdc

可以显示smart信息

四，利用smart快速评估硬盘健康结果

root@debian:~# smartctl -H /dev/sdb
smartctl 7.2 2020-12-30 r5155 [x86_64-linux-5.10.0-9-amd64] (local build)
Copyright (C) 2002-20, Bruce Allen, Christian Franke, www.smartmontools.org

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

smartctl -H /dev/sdb

看到最后的PASSED，表示这个硬盘近期没有问题，可以放心使用。
