SmartMonTools是一款开源的硬盘检测工具，包括smartctl和smatd两个文件，可以帮助用户快速的监测硬盘的健康状况，并且可以在发生故障前进行预警，支持SMART的硬盘。

使用方法

1、启动监控进程

# /etc/init.d/smartd start

启动 smartd： [ 确定 ]

2、检查硬盘是否支持SMART 1993年以后出厂的硬盘基本上都支持SMART技术，使用如下命令可以来查看：

# smartctl -i /dev/hdb

smartctl version 5.33 [i686-turbo-linux-gnu] Copyright (C) 2002-4 Bruce Allen

=== START OF INFORMATION SECTION ===

Device Model: ST3160212A

Serial Number: 5LS2EDKN

Firmware Version: 3.AAE

User Capacity: 160,041,885,696 bytes

Device is: Not in smartctl database [for details use: -P showall]

ATA Version is: 7

ATA Standard is: Exact ATA specification draft version not indicated

Local Time is: Mon Sep 17 02:13:37 2007 CST

SMART support is: Available - device has SMART capability.

SMART support is: Enabled

在上面的信息可以看到，该硬盘是支持SMART技术，且当前是开启的。如果SMART support is: Disabled表示SMART未启用，执行如下命令，启动SMART：

smartctl --smart=on --offlineauto=on --saveauto=on /dev/hdb

3、检查硬盘健康状态

# smartctl -H /dev/hdb

=== 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。SMART只能报告磁盘已经不再健康，但是报警后还能继续运行多久是不确定的，通常，SMART报警参数是有预留的，磁盘报警后，不会当场坏掉，一般能坚持一段时间，有的硬盘SMART报警后还继续跑了好几年，有的硬盘SMART报错后几天就坏了，千万不要存在侥幸心理。执行如下命令可以看到详细的参数：

# smartctl -A /dev/hdb

202 TA_Increase_Count 0x0032 100 253 000 Old_age Always - 0

FLAG是标记，标准数值(VALUE)应当小于或等於关键值(THRESH)。WHEN_FAILED 代表错误信息，上面显示的WHEN_FAILED纵行是空行，说明硬盘没有故障。如果WHEN_FAILED显示数字，表明硬盘磁道可能有比较大的坏道。

4、对硬盘进行检测 手工对硬盘进行测试的方法有以下四种：

smartctl -t short 后台检测硬盘，消耗时间短

smartctl -t long 后台检测硬盘，消耗时间长

smartctl -C -t short 前台检测硬盘，消耗时间短

smartctl -C -t long 前台检测硬盘，消耗时间长

例如，在后台对硬盘进行详细的检查，命令如下：

# smartctl -t long /dev/hdb

=== START OF OFFLINE IMMEDIATE AND SELF-TEST SECTION ===

Sending command: "Execute SMART Extended self-test routine immediately in off-line mode".

Drive command "Execute SMART Extended self-test routine immediately in off-line mode" successful.

Testing has begun.

Please wait 54 minutes for test to complete.

Test will complete after Mon Sep 17 03:53:32 2007

Use smartctl -X to abort test.

上面的信息显示54分钟后将完成检查，同时可以使用 smartctl -X 终止检查。终止硬盘检查命令的使用方法是：

# smartctl -X /dev/hdb

5、查看硬盘日志 使用“smartctl -l logtype ”可以查看硬盘的日志，日志又分为多种类型，如selftest、error等等。例如查看硬盘检测的日志，如下：

# smartctl -l selftest /dev/hdb
